Better to say it's a typical GMT, and not at Rolex prices. :lol:

I'm happy with it too. :clap:

Well, in the common watch lingo, it's a GMT, but not a true GMT.

I'm surprised JJ has not modified the movement to do that. Is it difficult??

Does it really make much difference though?

I mean, how long does it take you to change the time on your watch? Does it matter if the other hands stop too?

A SH21 GMT is in the works but it's going to be expensive. I like GMTs but don't need one so at that price I am out. It makes more sense to sell the lesser GMT movement at a much more appealing price as they are with the new line because for most it's good enough. They are gonna get a lot of GMT 600 sales from people who only normally buy divers, you bet!

The ETA 2893-2 used on the GMT 600 is the brother of the famous ETA 2892-A2, and is better than the ETA 2824-2 or Sellita SW200-1 used on the PRO 300/600. It is slightly more accurate and feels much higher quality when winding. The GMT 600 offers the best value of the new line, IMO.
I agree here. I have a problem spending 600 quid on a 2824 based watch because I know it will likely not be accurate enough for me (based on my C8, what I've read and CW's stated +- 20 sec /day).
However, my Omega with a 2892 derived movement (also a 'proper' GMT) manages about 2 or 3 sec / day, so I have a lot more faith in the 2893-2 Trident GMT.

Loving the burgundy, although the bezel markings take a bit of getting used to.
Good stuff lol

So, you have this wonderfully accurate Swiss watch.. You jump on the plane from London to Copenhagen. During the flight you want to set your watch to local time, but you have to stop the movement to move the hour hand... Next day you whizz to Moscow and repeat the process...

With a true GMT, the watch movement keeps going and the accuracy is maintained.

Of course it doesn't make much difference, but then again, it wouldn't make much difference if we all wore radio controlled Quartz watches....

If time really was that important to you, you would wear a radio controlled watch.

I set my watches from my phone or TV every morning. I'm never late for meetings or the train due to my watch.

I thought the 'true' GMT meant that you could change the regular hands and the gmt hand would still show gmt, whereas with CW and many others the gmt hand is a fixed offset so when you advance the regular hands by say an hour, the GMT hand also advances by an hour and therefore needs resetting back to GMT every time you change timezone?

Or did I make that up?!

I think there is some confusion...

In the two types of GMT (for simplicity, the Rolex type/True GMT and the 2893 type/Regular GMT), the essential difference is simply how the hour hands are controlled.

In the True GMT watch, the main hour hand is advanced using the crown at the first position (without stopping the movement), and the secondary hour hand (the GMT indicator) is advanced with the crown at the second position. When using the crown, the minute hands move with the secondary hour hand. So... You set the time to GMT with the crown in position 2 and then move the crown to position 1 and set the main hour hand to local time.

In a 2893 GMT watch, it works the other way around. The secondary hour hand (gmt indicator) can be altered in position 1, and the main hour hand is altered with the minutes hand at position 2. So... You set the time to local with the crown in position 2 and the move the crown to position 2 and set the GMT hand to GMT.

In both cases, the hands are connected so that in normal operation the GMT hand follows the main hour hand - although, obviously, the GMT hand rotates once per 24 hours instead of the normal 12 hour rotation of the main hour hand.

So, it is horses for courses. If you mainly stay at home but want to track another time zone, the 2893 works well, and if you often travel across time zones but want to track your 'home' time zone (or GMT/Zulu/UTC), the True GMT system is more convenient.

That is what I thought the true GMT offered. I don't think Richards technical explanation conflicts with your view. In practical terms, and regularly travelling to ZA and Oz as I do I can't think of a single advantage of the 2893 GMT. After all, GMT remains constant wherever you are and it is helpful if it remains so on your GMT watch.

I bought my first CW watches about a year ago (a C11 Titanium Elite and a C8 Pilot Mk II) and I'd been thinking about adding a C60, so having seen the new ones I'm glad I waited.

The GMT is tempting but I have a feeling it won't work with the use case I have in mind: tracking India time zone. For those who don't know, India are right now 5 1/2 hours ahead.

Does anyone know whether or not the C60 can manage that? I suspect not, since I'd guess the GMT complication is only designed to move the second hour hand in whole hour increments.

Think I'm getting this... When I go to another time zone I change my Rolex Explorer to local time on the first notch while the rest of the watch keeps running normally and the GMT hand stays the same. The ETA movement does it differently - and not as efficiently?

Welcome to the forum. You are correct, the C60 GMT (along with the vast majority of GMT watches) cannot handle half hour time zone differences.
