Anyone use their GMT function?

When I used to travel a lot for work, I'd do multiple cities in multiple time zones. A simple GMT wouldn't cut it but I used my worldtimer extensively...

I looked a long time at diff watches and how their GMT or worldtime worked. While many diss the JLC 2nd timezone subdial, it worked just fine for me. And, the mech and fcn of the JLC was superior to the rest, imo.

I cannot be bothered with the maths.
I'm on holidays.
Quick glance at my GMT and I know my home time.

For keeping track of global teams and meetings, I also use the World Time app on my iPhone.

GMT in my EXP II is simply to have local time at a glance during meetings where checking a phone is seen as rude / impolite and I can also quickly see home time if I want to step out and call my wife or daughter during their short window between waking and leaving for work or school.

You are making a ton of assumptions about me that are off the mark...

was I? Or was I just blabbing via text on an Internet forum where brevity is as misapplied as spelling? I was simply recounting one possible hypothetical that could be derived from the little info you provided - I wouldn’t have put any bets on it, nor thought it needing defense. And just the same, I too was providing OP my contrary opinion to your original statement. You know, conversation...

That's where the iPhone cal comes into place....Because If I have that many critical items while jet lagged to remember the exact time is not the biggest challenge for me. Also you would have to change your GMT about six times to meet all those times, which will need the same math.

At that point the GMT crown is going to disintegrate man.....no watch can track all that for you without about 6 changes.

Which pre-agreement I mentioned in my original post above (RE still plenty of math to do), and referenced again in the one you quoted (RE a “crutch”): I still have to do plenty of math, with the GMT simply providing a useful “crutch” by (if nothing else) giving me at least two touch-points with reality: e.g., my “local” time pre-set showing me my Alaska destination, from which simple math allows me to get to Denver (+2, my layover), TX (+3, my home) and NY (+4), while my “home” set to Sydney gives me each of (a) instant info RE Sydney time (+20, with possible variable date), (b) AM/PM at Sydney, and (c) a second global point from which simple math can give me Tokyo (-2), Malaysia (-3), etc.

The phone/laptop calendar are also critical of course, but at times in transit can introduce as much confusion as assistance: for example, halfway in flight between Denver and Alaska, in-flight wifi goes out over “international” airspace, and the phone may or may not be showing Denver, West Coast, or AK zone (depending on if or when the phone picks up a signal, is logged in/out of in-flight Wi-Fi, or once landed has yet reconnected to a local tower). Thats all before mentioning I have two cell phones, an iPad, all in various states of auto time updates, plus a laptop calendar itself that doesn’t auto-correct time zones unless I’m logged into my corporate Citrix portal. In all, while in transit, I carry a deep suspicion of both my electronic times and calendars - because a 5% error rate is enough to be anxious about miss-understanding a calendar alarm.

Under all that, my GMT (properly attended to) again gives me a reliable touch-point from which to base still plenty of math, and also confirm electronic times/calendars.

Anyway, I hope you and @Archer both appreciate I’m here not arguing for any objective reality that is superior to any other, but instead just gabbing on an Internet forum about how (a) “tool” watches all are in some real sense totally obsolete to a degree, yet (b) can to the extent of that delta still be valuable “tools” for some more than others, while (c) being otherwise purely emotional purchases for which there is no good “reason” in modern times (save for a fear of the end of modern times)

Not to mention, it’s worldtime is among those that use “Chicago” to name CST, rather than “Mexico” ... which just seems more like “home”

I always thought a purpose of the GMT was to show AM/PM, like on the Explorer if you're trapped in a cave for long periods, or kidnapped and held in a closed room.

So naturally I have a GMT just in case.....😎

Hey, I am having my own conversation with you, don't mix me with Archer who is having a separate conversation with you. This is not an issue of sides.

At least my phone calendars keep track of it all for me when it comes to multiple time zone events. as for the rest, I do use the GMT function myself but admittedly it is mostly because it's there so.....I might as well use it.

All good.

The GMT aspect is handy ……but tbh…the slide rule bezel, is more useful, for rough currency / temperature conversions

use it occasionally which is more often than i use the tachy bezel on my Speedmaster. But if we all only purchased watches that we needed functionally then what kind of world would we live in?
that way only lies madness 😜😜

oh man now you're really taking things way over my head. I already find the GMT function too intellectually taxing and just like the look of the bezels and pointer hands.

Yes. Because I have a habit of getting trashed at festivals abroad and have no clue which end of the day I'm meant to be at.

I used it all the time on when I had to make calls to other time zones around the world. It was quicker and easier for me. Damn it Jim, I'm a (doctor) microbiologist, not a mathematician.

The number of anti-magnetics that see Wiley Coyote’s giant ACME horseshoe magnet?

You will be comforted to know that he has retired from his previous pursuits, has gone vegan, deals with his OCD although a daily struggle, and is now a respected MRI tech at a local hospital in New Mexico. And he wears a vintage Milgauss.

I have both GMT and a JLC Master Geographic and have used the timezone function because it is convenient and fun.

Do I need it …. no , but I like the watches and the timezone functionality.

Mind you they are both useless when you travel to India since they can only handle full hour timezone differences
