GMT Master 2 (Ceramic) - How many bezel clicks? Can you stopwatch with it?

[Utini]

Hey there,

if the internet is correct then the old GMT Master 2 (aluminium bezel) had 120 bezel clicks while the new one (ceramic bezel) has 24 clicks although it will also lock in between?

So it should lock every 2,5 minutes?
That would give it the potential to use it as stopwatch? Although not as good as the old GMT or a sub?

Thanks in advance !

If you want a stopwatch, the Daytona is the one you want. Or better yet, the Omega Speedmaster.

i'm not a gmt expert but, i didn't know a 5d gmt had any clicks.

the 6d has 12 i believe, but i'm not 100pct certain.

[breitlings]

you qre correct 120 vs 24. imho daytona is a special watch as is 16710.

The 6 digit GMT II has 24 "clicks."

Click? GMT2c bezels dont click - wtf is ppl on about? Its completely different to a sub bezel.

116710 = 24
16710 = 120

I think timing should be done with a chronograph

Hmm that makes me wonder if the 2003-2007 GMT with aluminium bezel might not be the better choice.

120 clicks are perfect for timing when grilling, making an egg for breakfast or whatever !

24 are not qccurate enougj I believe...2.5mins more or less on a steak are night and day !

Great posts from some.

Not so good from others.

Insert "shakes head" emoji.

My GMT TTc bezel has 24 clicks (positions for the pedantics) so is not much good in South Oz where we have that half hour time difference.

It can be positioned between the clicks but is easily bumped either way.

It is not designed to be a timing bezel as the rocket scientists here have found out.

Best to just use the minute and second hands for that?

I also have a 120 position GMT back-up for accuracy.

The clicking mechanism, a simple bar spring, fails quite often on the 5-digit GMTs. Fortunately it's a simple fix and the part costs about $10 (eBay). My 16710 wasn't clicking and I assumed it was simply a friction bezel. Nope!

On diving models the end of the spring is straight so the bezel is uni-directional. On bi-directional bezel models the end is bent into a V with the V point making contact with the inside of the bezel. I had to bend my replacement spring ever so slightly to add more curve, and I bent the V tip up slightly too, ensuring better contact with the inside of the bezel. Clicks like a sonofabitch now. :)

Thank you !

Now I wished I had bought a non-ceramic GMT about 6 years ago :(

Getting one now in good condition with box and papers is more expensive than a new ceramic GMT :(.

One of the things I've noticed is the clicks on the GMT are no where near as crisp as the ones on the Sub are. This is likely because of the mechanism ras described but something worth mentioning.

If stopwatch capability is a criteria for you, then I agree with the others to look at the Daytona or Speedy.

I actually use my ceramic GMT to time stuff like things on the grill or in the kitchen, but as previous posters have pointed out, there are fewer stops with the newer models compared to the aluminum versions. Nevertheless, it works fine for what I use it for.

I would only use the stopwatch / timing function for simple stuff like you do (e.g. grilling). The 120 clicks would be perfectly fine for that.

The prices for the older GMT are just not reasonable at the moment. A new unused ceramic GMT iw cheaper than a used aluminium GMT.

I wonder why Rolex decided to change from 120 to 24 stop positions. Does anyone know?

It would make it less functional and so ppl would need to buy both..a GMT and a Sub ?

Because the bezel correlates to the 24 hr hand; one position for each hour.

The previous 120 click bezel was simply a carry over from the TOG bezel and not unique to the function of the GMT.

Thanks Larry, always wondered about that. Interesting the Rolex didn't do it sooner on the 5 digit.
