Sojourner #039: Redeeming the Time - Field Watches for the Kingdom Worker

"Look carefully then how you walk, not as unwise but as wise, making the best use of the time, because the days are evil." (Ephesians 5:15-16)

Series: Field-Tested

Time. Ever passing, never pausing, given not gained, and rushing on like the rivers - whispering in the wind of a thousand empires, their banners fallen and names long forgotten, still marching forward, commanded by the One who holds all hours in His hands (Daniel 2:21; Psalm 31:15). Stewarded well, time can be used as a weapon for the wise (Ephesians 5:15-16), a tool for the faithful (Colossians 4:5), and a reminder that the day is drawing near (Romans 13:11-12).

Yet, the world today burns time like the fuel of a dying kingdom - scrolling, streaming, and consuming, melting under the weight of their own delusions - believing the sands of time will never slip through their hands (Ecclesiastes 1:2-3). Though, the people of God know better. They understand the nature of time, knowing it is carved by the hands of the King, given freely in measure according to grace (Acts 17:26-27) - each second a chance, each hour a choice. Not of fate, nor of fleeting will - but by His power (Proverbs 16:9). The days are evil, we know that best - we know ourselves (Ephesians 5:16; Romans 7:18-19). The gift of time is not best used for comfort and gain, but for His Kingdom (Matthew 6:33).

In the field, where the rhythms of the world are often unpredictable and unreliable at best, time is one of the most valuable resources the missionary has, second only to the Gospel they carry (2 Timothy 4:2). On the ground in northern Nigeria, in the border heat of Cúcuta, and amid the passing shadows of Riyadh, a reliable watch is more than a tool - it is an ally, marking the passage of time with quiet reservation, ever committed to its cause. Faithful. Unyielding.

This article is meant to serve as an actionable guide for redeeming the time we’ve been given (Ephesians 5:16), to help select practical, durable, and faithful watches for those laboring for the Kingdom - for the sake of His name among the nations (Malachi 1:11). 

So whether you spend your time in armored convoys or at an office desk, dodging hostile checkpoints or deciphering endless spreadsheets, it is our ambition to help you steward your time for His glory and for the good of His people (1 Peter 4:10), as you run with endurance the race set before you, making the best use of your time - for the days are evil (Ephesians 5:16).

I. Why Time Matters in the Mission Field

Let’s be clear, accurate timekeeping is not just about efficiency - it is about faithfulness. Selecting a field-ready watch first requires that you understand what it is for. A watch is a tool, but it is much more than that - it is a reminder to steward the hours God gives in rhythms of grace, to honor those you encounter by caring enough to be on time and maintain good discipline in places where infrastructure is sincerely lacking.

A Mission-Ready Watch Will Help You:

• Stay grounded when tech fails (because it always will).

• Keep rhythm when schedules shift (because they always do).

• Maintain good discipline in places where structure is scarce.

• Minister faithfully across multiple time zones or languages.

II. What Makes A Watch Mission-Ready?

Not all watches are equal in the field. Not all watches are built to the standard necessary for hard use by hard people in hard places. There are a ton of terrible options out there that can seriously damage your credibility, compromise your cover, and even derail your mission. Some watches may look the part but fail under fire, while others may tick too loud or die too fast to be usable. 

The wrong watch isn’t just an inconvenience, it is actually a liability. If you cannot keep a reliable measure of time on the ground, in places where life expectancy is often measured in minutes, someone will suffer - and it won’t just be you. 

This Is What To Look For:

• Durability: Water resistance, shock protection, and scratch-resistant materials.

• Legibility: Clear, high-contrast dials or backlit displays, strong lume (more on that in a minute).

• Low Profile: Avoid “luxury” watches or flashy designs in sensitive areas - watch theft can be a major issue.

• No Dependence on Charging: Solar, quartz, or automatic movements are preferred.

• Practical Features: Alarms, timers, dual time zones (GMT), GPS, or rotating bezel.

III. Choosing The Right Watch For The Mission Field

Not every watch fits every application. The situation you find yourself in, and where, has a great deal to do with the equipment you select. Furthermore, selecting a watch for Kingdom work isn't just about style. Let's hit that again.

Choosing a watch for the field is not just about style. It is about function, reliability, and the ability to serve without distraction. Context matters. Ask yourself questions that help you choose the right watch for the mission.

Five Good Questions To Ask:

1. What Is Your Operational Context / Area Of Operations?

• Urban / Cross-Cultural Ministry: Choose a low-profile, culturally sensitive watch (Arabic dial, classic analog, not flashy).

• Rural / Jungle / Off-Grid Work: Go for rugged, shock-resistant, solar-powered / automatic movement watches that don’t rely on electricity.

• Maritime / River / Coastal Areas: You’ll need something with at least 100m water resistance, ideally 200m (like a dive watch).

• Security / Medical / Night Ops: Consider watches with always-visible lume (like tritium) and a simple dial for quick time reading.

Match environmental needs to watch features to the best of your ability. Your situation dictates your equipment, always.

2. Will You Be Near Electricity or Batteries?

• Yes: Quartz watches (battery-powered) are affordable and reliable, but you still need a backup - “one is none, two is one.” As silly as it is, it’s true.

• No: Go with solar-powered or automatic watches that don’t need battery changes for years (or ever). A Quartz battery will always die when you need it most - if you do go that route, be meticulous about changing the batteries on a yearly schedule.

3. Do You Need to Keep a Schedule?

• If your mission depends on strict timekeeping (discipleship meetings, medical rotations, prayer hours, strict operational schedule), look for things like:

• Multiple alarms, timers and stopwatches

• World time or dual time zones (GMT feature)

4. Do You Need to Stay Discreet?

• In closed countries or hostile regions, avoid watches that draw attention or signal wealth - not only does it hurt your credibility, but watch theft is a rising issue in many developing nations and major cities around the world.

• Stick with plastic/resin cases, black or neutral tones, no polished metal. Think about what attracts attention to you, and what does not. Context matters.

Pro-Tip: "Blend in. Never outshine your context. Consider your application." (Contractor [GWOT] / Police Officer, Retired - United States, Anonymous)

5. Will It Survive Your Mission?

• Can I read it in the dark? (how strong is the lume?)

• Will it handle water and dust? (50/100m minimum)

• Can I replace the strap if it breaks? (NATO, rubber, metal, leather?)

• If it dies, can I find parts or a replacement? (batteries, glass, etc)

Bonus: Have a Backup Watch

Even the best gear fails at times. Bring a second watch (like the $15 Casio F-91W) so that timekeeping doesn’t stop if your main watch goes down - action is always better than reaction.

IV. A Word About GPS Watches: Use With Caution

The Appeal:

GPS smartwatches like Garmin, Suunto, or Apple Watch offer advanced tools: maps, health tracking, coordinates, and communication. They are also the most popular watch made today, even in most tactical settings. They're incredibly tempting, and convenient - especially for solo or deep-field work where you spend large amounts of time off-grid, and in urban environments where most people are wearing them. They can be a viable option, but understand:

The Risk:

In closed countries or sensitive regions, GPS data can (and likely will) be used to monitor your movement. Smartwatches often ping location data via Bluetooth, Wi-Fi, or cellular, even when background apps are disabled. Why is that a big deal? Allow us to explain:

In Some Cases:

• Authorities can use metadata to reconstruct your movements (building a pattern of life and exposing your location to hostile elements).

• Seized gear, or even a Bluetooth scan can expose your contacts (and endanger local partners, as well as your friends and family).

Recommendations:

• Avoid GPS or cellular-enabled smartwatches in restricted or surveillance-heavy regions.

• Use standalone watches (no syncing or apps) to maintain field integrity - they’re cooler anyway. If GPS is truly necessary, then use a dedicated GPS device that can be turned fully off between uses - and always remove the battery after use, if possible.

Pro-Tip: “When I work abroad in rural villages with no street signs or cell service, I carry two watches - one of which is a GPS watch. To minimize tracking risks, I keep the GPS watch turned off, and I never connect it to Bluetooth and phone pairing. If you use it right it can be a very effective tool, you just have to be smart about it.” (Operations Advisor - Central America, Anonymous) 

“Be wise as serpents and innocent as doves.” - Matthew 10:16

V. Watches Built for the Mission Field: Our Recommendations

Mission work demands tools that won’t fail when you can’t afford them to. Whether you're coordinating relief efforts in the tropics, hiking to remote villages, or praying with underground church leaders in restricted zones, a reliable watch is vital. These selections aren’t luxury items. They’re field-tested options for those working in rugged, unpredictable, and often hostile environments - for the Kingdom.

Digital Tool Watches:

Editor's Note: Yes, there are several Casio options here. What can we say? They make good watches. The selections in this section (and throughout this list) are watches that we actually use. Take that for what it is worth.

1. Timex Ironman

• Why it works: Inexpensive, lightweight, and packed with functions (stopwatch, countdown timer, three programable alarms, indiglo backlight) with no need to charge. Classic design.

• Tactical advantage: Multiple alarms help structure daily rhythms - prayer, teaching, meetings. Reliable even in blackout conditions. Blends in everywhere, not “tactical.”

• Field scenario: Organizing a VBS or medical clinic schedule in a rural area with no cell service and a need to be on time.

2. Casio World Time (AE1200 / “Casio Royale”)

• Why it works: Low-profile, ultra-affordable, and packed with global utility. 31 time zones, 5 alarms, stopwatch, countdown timer, 10-year battery, and LED backlight - all for under $30.

• Tactical advantage: Ideal for missionaries working across regions or supporting teams abroad. Keeps you synced with home base, field partners, and sending churches without needing a smartphone.

• Field scenario: You’re coordinating short-term teams across borders and time zones while maintaining contact with national partners and churches back home. It’s pre-dawn in your village, mid-morning at HQ, and evening where your next flight lands.

3. Casio G-Shock (DW5600 / GA2100 / GW-M5610)

• Why it works: Virtually indestructible. Shock, mud, and water-resistant. Solar-powered options mean total independence from batteries.

• Tactical advantage: Built for chaotic, high-impact environments - disaster zones, war-torn areas, or jungle terrain. Trusted by militaries and law enforcement agencies the world over for their durability - but may scream “tactical” in certain contexts.

• Field scenario: Church planting in post-conflict areas where basic infrastructure is gone and you’re sleeping rough.

4. Casio F-91W

• Why it works: Cheap, dependable, globally recognizable. Extremely long battery life. You could lose it and pick up another locally. Fan favorite of Sojourner’s Editorial Staff.

• Tactical advantage: Blend-in appeal. Doesn’t draw attention in sensitive or protected regions. A fantastic option for a backup watch, or a low visibility primary option.

• Field scenario: Evangelism in closed countries where low-profile presence matters more than tech - where simplicity matters more than flashy.

Pro-Tip: "I found an old Casio F-91W of mine the other day. The crazy thing is, I haven’t touched this watch in a decade, and the time and date were still right! Toss one in your kit bag and forget about it - it’s a no-fuss, reliable companion when you need it." (Cross-Cultural Missionary - Central America, Anonymous)

Automatic / Quartz Tool Watches:

1. Seiko Arabic Dial (SNK063J5 / SNKP21)

• Why it works: Automatic movement (no batteries), discreet Arabic numerals aid cultural sensitivity in Muslim-majority contexts (and gives you street-cred with the watch community).

• Tactical advantage: Builds bridges in language-sensitive regions while quietly avoiding western flashiness. Automatic movement ensures the watch will run as long as you do.

• Field scenario: Teaching ESL or sharing Scripture in North Africa, where cultural respect opens gospel conversations in sensitive contexts or applications.

2. Bertucci A-2T or A-5P Field Watches

• Why it works: Simple, unbreakable field watches with fixed spring bars and rugged NATO straps. Meant for hard wear. Inexpensive.

• Tactical advantage: No flash, no worry. Just works. Extremely low-maintenance. Hard to break, harder to lose.

• Field scenario: Manual labor missions, remote discipleship travel, jungle crossings.

3. Sangin Instruments Dive Watches

• Why it works: Built for special operations - automatic movement, sapphire crystal, tritium lume, and 300m water resistance. Mission-born and field-proven.

• Tactical advantage: Virtually indestructible. Excellent in extreme environments. No digital signature - but may be recognized by other watch enthusiasts or operators, not many librarians wear Sangin watches.

• Field scenario: Remote field ops, long-term deployments, or dynamic operations in high-risk areas.

4. Casio Duro (MDV106)

• Why it works: 200m water resistance, rotating bezel (great for timing events), tool-like simplicity. No-nonsense. Affordable. 

• Tactical advantage: Excellent for coastal or river missions, where humidity, rain, or baptisms are daily realities. Low visibility dive watch option.

• Field scenario: Ministering in river-based villages, or leading water-based baptisms on the fly.

5. Seiko Diver (SKX007 / SRPD series)

• Why it works: Tough automatic dive watch, ISO-rated water resistance (on SKX), conservative appearance. Rotating bezel to track time. Lasts a lifetime.

• Tactical advantage: Holds up in rugged environments while maintaining respectability in formal or church settings. Good for maritime operations.

• Field scenario: Transitioning from field operations on a river to a church leadership meeting in town, all without switching watches.

Pro-Tip: “I’ve worn a Seiko my entire career - through early mornings, late nights, and more than a few moments where timing mattered. Obviously, it hasn’t failed me yet. Rugged, reliable, and always ready. When in doubt, Seiko out.” (Military Officer - United States, Anonymous)

6. Marathon Navigator / General Purpose Quartz

• Why it works: Military-grade, tritium lume (glows constantly), quartz precision, no frills. Issued by the U.S. Military.

• Tactical advantage: Excellent for night work, security missions, or medical aid in dark, dangerous environments. Bombproof.

• Field scenario: Providing trauma care or coordinating underground meetings in the middle of the night.

NATO / OTAN Watch Bands:

If you decide to go with an automatic or quartz style watch, consider switching the band to a NATO / OTAN style watch band. These are a type of nylon watch band developed originally by the British Ministry of Defence in 1973 (write that down). They’re known for their durability, simplicity, and extra security - which makes them popular among military personnel, adventurers, and everyday wearers alike.

Pro-Tip: "In the field, you can't afford to be caught off guard. NATO straps are tough, offering that extra layer of security if you lose a watch pin. Whether you're tracking through dense terrain or heading into town, it's easy to switch bands to fit the task at hand, keeping you prepared no matter where the mission takes you." (Gear Expert - United States, Anonymous)

GPS / Compass Tool Watches:

1. Suunto Core

• Why it works: ABC watch (Altimeter, Barometer, Compass). Lightweight with good battery life and useful in rugged, high-altitude environments.

• Tactical advantage: Navigation and weather-tracking without GPS risk. Essential in places where terrain and storms change everything.

• Field scenario: Mountain missions, highland trekking, or pioneering evangelism where maps are obsolete.

Pro-Tip: "I used my Suunto Core to run backup ABCs in a Cessna Skyhawk last year, and during more than a few maritime operations. It goes with me wherever I go - from the tropics to the mountains, I've had the Suunto Core on my wrist through it all." (Not-A-Pilot - United States, Anonymous)

2. Garmin Fenix 5

• Why it works: Multisport GPS smartwatch with top-tier durability, long battery life, and heart rate/sleep metrics.

• Tactical advantage: Deep utility - maps, time zones, alarms, metrics. But be cautious: GPS & Bluetooth can compromise security.

• Field scenario: Physical endurance, remote field surveys, or logistics-heavy missions (where operational security is not critical).

Final Word: Time for the Task

The days are evil, we know that. The harvest is plentiful, we know that already too. And the laborers are few. Time is short - and it matters. Whether you’re shepherding a church in the slums or bringing medicine to forgotten islands, choose your tools and be faithful. Remember, a good watch will never change the world, but it can help you be faithful in the small, daily moments that do.

“Teach us to number our days, that we may get a heart of wisdom.” - Psalm 90:12

Editor’s Note: The Gospel We Carry

Time marches on. Kingdoms rise and fall. Names fade. But one name endures forever.

The Gospel is not a slogan - it is news. Good news. In a world burning time like kindling, lost in endless distractions, God has spoken. He has not left us to drift.

Each of us has wasted time. Each of us has fallen short (Romans 3:23). But Jesus Christ, the eternal Son of God, entered time. He lived without sin, died in the place of rebels, and rose again, defeating death (1 Corinthians 15:3–4). He redeems the broken. He restores the weary. He gives eternal life to those who come to Him in faith (John 3:16).

This Gospel is the reason we go. It’s the message we carry, whether through mountain passes or security gates, in border towns or across office desks. It is the power of God for salvation (Romans 1:16), and it is yours - right now - if you will turn from your sin and trust in Him.

Time is short. Eternity is real. Christ is calling. Will you respond?

FIELD-TESTED: Tools for the Task. Time for the Kingdom.

In airport terminals and alleyway cafés, on mountain trails and market roads - your gear won’t share the Gospel, but it might help carry it.

This isn’t about tactical obsession. It’s about faithful preparation. The right gear doesn’t exalt the traveler - it serves the mission. It stays quiet, stays ready, and helps keep your hands free and your focus sharp. Because the time is short, and the King is worthy.

Sojourner Magazine is launching Field-Tested, a new series of grounded gear reviews for those on mission and those who send them - so the nations may know.
