It only worked cause it was almost 12am. The correct way is to point the hour hand at the sun and then south is HALF WAY between the hour hand and 12am (1pm for daylight saving time).
@@enasnI127 My understanding is that you're describing the way you would use a normal, non-GMT as a compass. With a 24 hour GMT hand set to local time the GMT hand will point north with the hour hand pointed at the sun, and south will still be half way between the hour and the 12.
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 both and I agree but there’s something oddly satisfying to jump that hour hand back and forth. I know I’m causing extra wear and sometimes in the wrong direction but I will give out before my watches at this point.
Doh.. I spent a whole 5-minutes writing a reply and now I see you've pretty much covered the "pilot stuff". However, I do reset my watches at top of climb, even for a short overnight and especially for a longer layover. Most pilots I observe, do it your way and just leave it on hometime. But with the true GMT function, it's just so easy. My older ETA "office caller" movements seemed to need service quicker (about 4 years) due to the wear and tear. So agreed on that.
@@duck853 thanks for sharing your experience. Those mechanical watches are made of so many tiny gears. Better not to mess them up by constantly changing the hour hand. Why not just rotate the bezel
@@erikdupont554 I totally agree after having to service my Fortis 3 times in 12-years. I've since stopped taking "office/caller GMTs" on the road and exclusively go to work with real GMT movements. Clicking the hour hand only has been a gamechanger and less wear and tear. Why? I just like to look at the watch and be able to tell the local time quickly the older I get. I'm a visual learning guy and seeing the hands without having to do the math suits me. It helps when going from zulu -7 to zulu +9 within 13-hours. I bought these things to use them. That includes the cost of servicing them. Honestly, the older I get the less I use the GMT function on the flightdeck as the clock on the instrument panel is just as quick. I mostly use the GMT function on my watch now while in the hotel reading the OFP, NOTAMS, and other planning products before stepping to the crew van.
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!
Great video! Not trying to be smug, I was baffled at RU-vid videos talking about the GMT hand for "home time" when I first got into horology. To each their own. As a professional pilot my GMT hand was ALWAYS set on... wait for it, GMT. Exactly as you said, flight planning and every product we use is in Zulu or GMT. It took me only a year or so before I invested in a GMT watch instead of having to try to do the math in my head all the time. Use the rotating bezel all the time. After awhile you memorize that Tokyo is +9, JFK is -4, and so on and you rotate as necessary. With the true GMT function I've given into setting "destination time" on the hour hand at top of climb now. It's nice to look at a glance to see what local time is where I'm landing.
Very nice. Always enjoy a good lesson on watches. You and Professor Marc from Long Island Watch are my two favorite lecturers on watches. 👍🏼. Although the only use I have for a GMT is I set the GMT time to my daughter’s time zone and when I wear my GMT, it just reminds me of her.
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 just moved into a new timezone and I opened RU-vid to learn how to track 3 timezones on a watch. This video was right on top of my feed. Talk about timing! Thanks
This ia why Seiko's SSK series of 5 Sports GMTs work so well for ne: as I don't frequently stray beyond my home time zone, a "caller" works best in my case, and having a 24-hour scale on both the dial/rehaut *and* rotating bezel, I can track two additional time zones without doing any head math. And, tge additional tricks you pointed out are neat as well.
Great video, Dave! Thanks a lot. I love a GMT and have owned a few over the years. I wonder if you would consider talking about worldtimers at some point?
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?
Yeah it's got a ghost date position. I'd much prefer if they had gone with a date, but I suspect stylistically they thought a no date would make for a cleaner dial.
Sir, Are there Japanese solar watches that have the legibility of the German pilot watches (easy to read)? The German Lago brand makes quartz pilot watches but aren't solar and require battery change. I have departed from mechanical watches because of the more accurate solar quartz movement. I am a subscriber that enjoys your unpretentious attitude. Be well and be safe, Val
I've got 2 GMT watches, and have absolutely zero need for them. I just love them! Only family I have in a different time zone is only 1 hour ahead, no big deal. Especially since we never talk to them anyways!
I like my vostok K-65, using a vostok 2431 movement. The dial has 24 hours instead of a separate GMT hand. Its essentially an Vostok Amphibia with typical 200m dive watch capability but branded under Vostok Komandirskie.
I've traveled quite a bit and as cool as a GMT analog watch is (I prefer analog watches myself), I use my Casio brick (5600 series) to see my required time zones. The main screen is set to my home time, then I set the world time (WT) mode screen to the 4 other needed time zones. 1: UTC, + 2, 3 & 4: to the other necessary time zones. If I am flying with a layover, I set my start home time, + my layover times and my final destination time. It is quick and easy to use and I can store 5 time zones on the watch. I always travel with at least two watches, my solar powered casio quartz and an automatic watch, which I set to wherever I am in the world.
You can talk at half the speed and impart the same amount of information. You also move the watch hands back and forth so much that was completed unnecessarily and confusing. Why not move them slowly to where you want and stop and match the moving with narrative ? As if you were setting the watch for your own actual use ? BTW, using full hours as examples in the tutorial would also be much clearer.
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.
I've been into watches for years. But only recently have started to learn some basic horology and watch collecting. I'd been thinking of adding a GMT to my collection. After learning from this video, I realize that I don't have a true use for a GMT at this time. Adding one to my collection would be for looks only. Thank you for this truly valuable education.
One of your best videos Dave. Great content. I have my GMT hand set for GMT time. I can then move the bezel to the time I want to know and leave the GMT hand alone. All mine GMTS are the 9075. I generally leave the hour hand alone, but its nice to have the option and its useful for daylight saving time. I'm totally fine with no date. I typically know what the date is or can look at my phone and it saves me from having to set a date if I haven't worn it in awhile. Definitely a plus with no quick set date.
It depends. If the GMT hand is set to local time when you point the 12 hour index to the sun, the GMT hand points to South (at least in the Southern hemisphere). So when you are not traveling the watch doubles as a compass. Regards
Another GMT use for pilots are all actual weather and forecasts are of course UTC/GMT and the bezel can be handy when you’re planning a flight. Some pilots are actually not great at math.
Так как мне отслеживание даже двух часовых поясов редко надо,то мне больше нравится безель с городами, бывает просто интересно посмотреть который час в другом месте... А вот про компас-действительно проще чем на обычном трёхстрелочнике.👍
Thanks for the in-depth review! I've got a question for you. I was wondering, for a watch that has a small 24-hr scale on the dial and a relatively abbreviated GMT hand, does it perhaps make more sense for the bezel to be printed with a 12-hour scale? That way, the third time zone can be read using the regular hour hand instead of the GMT. Or am I missing something?
I haven't seen that particular combination before, but in general I'm a big fan of 12 hour bezels, as they allow you to do a lot of the same things a GMT hand does, and as you mentioned, sometimes they're even easier to read.
Great video!! Question; why is the Undone watch does not have a date? Most of GMT watches have date. Considering the NH334 movement has a date, I wonder why they did not put a date. Not a critique, I am curious.
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, during the Olympic game, 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.
Really appreciate educational vids like this However, I'd perhaps suggest being more careful with who you accept as a sponsor. I've seen nothing but bad feedback about them, from customers and reviewers alike. Their presence cheapens both this video and your channel, which a great channel like yours doesnt deserve
If you've had any negative experiences with them I'd be interested in hearing about it. This is my first interaction with them and haven't noticed any red flags.
@JusttheWatch other than them being cheap cash grabs with dubious qc and awful customer service, impossible to return their watches that show up broken, that follow every hype train, they steal content from small channels, remove reviewers branding and refuse to pay them, such as what happened to Adrian Barker. They are basically a scam
@JusttheWatch other than being a cash grab that follows every hype train, their shoddy qc, impossible to return their watches, zero customer support, as well as stealing (and heavily editing) reviews from small creators to remove reviewers branding and make the review more positive like what happened to Adrian Barker and refusing to pay them for their review. They are basically a scam
Who knew that to get the most out of a GMT watch, you have to use it like a GMT watch... That's so incredible:D But I guess people can't even figure that out for themselves...
I have 2 GMT watches, not naming the brands, which I just use to see home time. I don’t travel much anymore but I do like the colors on the watches, Pepsi and Batman.
Ya missed a trick! Timing elapsed hours. Use the the rotating gmt bezel like a dive bezel, but start it in alignment with the gmt hand instead of the minute hand.
You can! You just have to be aware of the AM and PM differences because a 12 hour bezel can't show that, but I also love 12 hour bezels because they can do time conversions really well too.
