How to Set a GMT Watch: Simple Step-by-Step Guide

A GMT watch is not just a watch with an extra hand. It is a tool designed for people who live across time zones. Pilots, consultants, remote workers, and frequent travellers rely on GMT watches to track home time while moving through different countries.

The key feature is the fourth hand, usually pointing to a 24-hour scale. That hand shows a second time zone. Once you understand this, everything else starts making sense.

Why Understanding How to Set a GMT Watch Matters

Here is the honest truth. Many people own a GMT watch and never use it properly. They leave the GMT hand pointing somewhere random, or worse, they stop using it altogether.

Learning how to set a GMT watch correctly means you get full value from what you paid for. It also prevents common mistakes like messing up the date or forcing the crown at the wrong time.

I wrote this because I have seen too many people feel intimidated by GMT watches. You do not need to be a watch expert. You just need a clear explanation and a few minutes of practice. By the end of this guide, you will feel confident setting and using your GMT watch anywhere in the world.

How to Set a GMT Watch

Let us walk through this together. I will explain it like I am sitting next to you, watch in hand.

Initial Setup: Getting Ready to Set Your GMT Watch
Before you touch the crown, take a second and identify what type of GMT watch you have. Most GMT watches under normal price ranges use an office GMT movement. That is what this guide focuses on.

Pulling Out the Crown
Start by gently unscrewing the crown if your watch has a screw-down crown. Once it is free, pull it out slowly.
Most GMT watches have three crown positions:

• Position one is for winding.
• Position two is for setting the date or the GMT hand.
• Position three is for setting the main time.

Do not rush this part. Feeling the clicks helps you understand your watch better.

Adjusting the 24 Hour Hand
Push the crown back to the second position. In this position, turning the crown usually moves the GMT hand independently. Now decide what time zone you want the GMT hand to track. Most people use it for homework. For example, if you live in New York and travel to London, set the GMT hand to New York time. Move the GMT hand carefully until it points to the correct hour on the 24-hour scale.

Synchronizing With a Reference Time Zone
Here is a trick experienced travellers use. Use UTC or GMT as your reference instead of home time. This makes mental conversion easier when travelling often. Whichever method you choose, consistency matters more than perfection. Pick one system and stick with it.
This step is the heart of how to set a GMT watch properly. Once you get this right, the rest is easy.

Setting the Local Time
Pull the crown to the final position. This moves the main hour and minute hands. Set the local time first. This is the time you are right now. If you are travelling, this is your destination time.

Important tip: Always check if the watch is in AM or PM by watching when the date changes. This avoids the most common GMT mistake people make. Once the local time is correct, stop and do not push the crown in yet.

Setting the Date (If Applicable)
If your watch has a date window, adjust it in the second crown position. Always do this outside the danger zone, usually between 9 PM and 3 AM. If you skip this rule, you risk damaging the movement. Take your time here.

Pushing the Crown Back In
Once everything looks right, push the crown back to its original position. If it is a screw-down crown, gently screw it back in. Give the watch a quick glance. Local time correct. GMT hand correct. Date correct. You are good to go.

Conclusion

Learning how to set a GMT watch is one of those small skills that pays off for years. Once you understand the crown positions and the role of the GMT hand, the fear disappears.

I encourage you to practice setting your watch a few times at home. Change time zones, reset it, and experiment. The more you interact with your GMT watch, the more valuable it becomes.

In a world where time zones blur and travel is part of modern life, a GMT watch is not just useful. It is empowering. And now, you know exactly how to use it.

If this guide helped you, share it with someone who owns a GMT watch but never uses the second hand. That conversation alone makes this worth writing.
