Re use as a compass: Local time used must not be daylight saving time.

GMT is the best complication in my mind. Simple, elegant, and doesn’t clutter anything.

Great explanation of GMTs, Dave! I was a C-130 navigator in the USAF, & we would deploy to the desert every couple years for 4 months. A “caller” GMT sufficed for me…I’ve got a Squale 1545 GMT with a Sellita 330. When deployed, I’d keep the normal handset on local, the GMT hand on Zulu, & the bezel on Eastern back home.

I liked using an analog GMT watch better than a G-Shock with similar capability. I could see all the times at a glance with no button-pushing!

Surely a GMT should have a date function?

"It's 4am in Japan and ... DEFINITELY NOT ...." hahaha😅😂😂. Great video Dave, still loving your channel. Keep up the good work.

I feel like I’m in school and my brain already zoned out the teacher because he’s speaking Chinese

Pilot here. What I do is just set the GMT hand to the GMT hour and the hour and minute to my home base time. Once abroad, I rotate the bezel for the GMT hand to match the local hour to be read on the bezel. I never reset or move the hour nor the GMT hand. I just rotate the bezel the way it was designed for. This is why the debate between the office (caller) vs traveller GMT doesn't make sense to me. You don't have to move the hour hand. This might even cause additional wear and tear to your watch. You only have to rotate the bezel!

I have a rolex gmt Pepsi, I don’t even set the timing at times . Just saying 😂😊

Thanks for the feedback on the GMT. Just got my first GMT watch from Zelos using the 9075 movement. One thing different on mine, is the bezel has City names. Not a traveler at this time, hope to travel later sometime.

I've heard that Undone can get effed for quite a few reasons...

Thank you for your video.
I love GMT watches. I owned three of them.
I used the GMT watch to monitor the British Premier League time for watching. I am sitting in Hong Kong. For the Bezel, I move back one hour because it was happened in Paris. So simple. Ha ha.

I am impressed more and more with your videos.

If I am in Iwata, would you be open to meeting up?

This is the clearest and most comprehensive GMT use video I have seen.

[halfsourlizard]

So, a watch with an NH34 but no date is a bit weird -- the GMT hand can only be advanced forward and rotating the crown the other direction just ... does nothing?

[ijrm]

I want to like the Wise but the hour hand reminds me of a pen*s, if they change it would love to get the Batman

[wongjefx]

This looks good....boderry GMT's are more affordable but are copies of Rolex Explorer II and SeaMaster. Undone is unique.

[pierredvumali]

Tips & tricks videos are really helpful. Thanks!

To me gmts would make more sense with a 12 hour bezel

[siebertperformance]

One of the most informational watch videos I have seen. Awesome job.

[scottgordon]

A good 24 hour bezel (preferably bi-directional) will get rid of most of the difference between a caller's and a traveler's GMT. Just set the GMT hand to actual GMT and use the rotating bezel to track a different time zone using the GMT offset. No need to hack and reset a traveler's GMT if you want to track home time and a 2nd time zone. I won't buy a GMT without a 24 hour rotating bezel.

Terrific video and great explanations, thanks.
