Hi Ru4scuba, I have the 2234.50 with custom bracelet. It's a great real GMT with a 24 hrs bidirectional rotation bezel and very, very precise. It's suitable snorchling and diving and was several times with me on the Maldives and South Korea. Perhaps I'll go for the Good Planet GMT but will never sell my 2234.50.
The 2538.20 (aka Great White) is the white version of the 2234, albeit with a different bracelet. Slightly chunky with loads of wrist presence, and very readable, day or night.
has to be 2234,50, with speedie bracelet it is the best looking GMT watch period! White is not too bad either.
Have owned a couple of Rolex GMT master but have just ordered PO GMT black bezel with orange numerals to accompany my Hour Vision Orbis. Arrives this week. I prefer it to the current Rolex with blue/black bezel partly on aesthetics and size but also the movement. Looking forward to it!
Vintage: Rolex orange hand Explorer. Yes, you read that right - a Rolex is my first choice. Modern: Maurice Lacroix Pontos Decentrique GMT. Just wish it was under 40 mm instead of 43.
Remember guys: A real GMT has a rotating 24 hrs bezel. A watch with a non rotating 24 hrs bezel is a simple watch with a second timezone. So i.e. the AT GMT and the Rolex Explorer are nice watches indeed but they aren't real GMT's. With a real GMT you have actualy 3 timezones and you can change it within seconds.
Man, I've never got this quite straight in my head. Is there a generally agreed-on definition of "true GMT"? There are a few definitions (eg. here , here and here) but which is the right one? (assuming there's even one!). All I know pragmatically is how to use my GW when I travel, but I'm curious and I'd like to know what the experts say
I have found numerous explanations on how a GMT works. Basically, a GMT is meant to provide the time in two time zones, the local time (your present location) with the 12-hour hand and the home time (where you live) with the 24-hour hand. Some watches allow the 12-hour hand to be moved independently (Rolex) and others allow the 24-hour hand to be moved independently (Breitling). A third time zone can be ascertained by rotating the bezel based on how many hours plus/minus you are from Greenwich Mean Time. I haven't figured this out nor am I going to try. The only practical use I have found for my GMT is when it runs down from not wearing it, I can tell if it stopped in the am or pm.
