Wonder why Rolex never put a bi-directional rotating bezel on this one, it would make it even more versatile and give us something to play with....

They did...

If your current watch has an ETA 28xx in it the hands are a direct swap. If it has a 21j you need new hands.

If it's a rep, it's a damn good one.

Every modded 2836 I've seen come out of the factory has had the jumping GMT hand for at least the last 2-3 years. I doubt yours is any different. A 2893 will be functionally the same.

Looks like the stem has broken off inside the movement looking at the thread on whats left of it.  If you can't extract the broken part out of the movement, by facing the tube down, and gent ally tapping the watch case, you are going to need to strip the keyless down to get the broken part out my friend.

Probably not. If you uncase the movement, and remove the stem like normal using a pair of tweezers or pliers, it should just come out. No reason to think the keyless is messed up just because the stem broke.

Better question is why the stem broke--the usual reason is sideways pressure on the stem due to incorrect stem height for the case. If this is true, the next one's just going to break too.

It looks like just the stem broke. A new stem is ~$3.

Not telling you not to buy a gen crown if you want one, but it doesn't look like there's anything at all wrong with your crown and this is a repair that can be done in under 10 minutes with under $5 worth of parts.

haha i was wondering...another dodgy asian dude!

My name is Won. What of it?

Wasn't his name Wong?

It looks like the Stem retainer screw has loosened or was not tight enough. 

ETA 28xx movements do not have stem retainer screws.

On a rolex though, he's gonna have to deal with the dwo, because you can't screw the cover plate for the time set gears back on with the overlay in place.

 

It can be done, it's just an enormous pain in the ass.

Why would you use a super-sea-dweller case? It's entirely wrong for the project. Most people who build tudor snowflakes use the 1680 or 5513 cases as a starting point.

Rubber cement is too soft. You're not trying to glue the parts together, you're trying to add material to the ID of the bezel ring.

Sad to say but there is not much of a fix for a snap on bezel that pops off easily. Either the crystal retaining ring or rotating bezel is out of spec...maybe both.

I have had some success fixing this by putting several drops of superglue on the inside of the bezel, letting it dry, then snapping it on the retaining ring and playing with it until it looks right. The superglue fills up the space and keeps everything tight. It's a crappy, ugly hack, but at least your bezel stays on.

The only "real" fix is to source another retaining ring or bezel ring that is the right diameter

(Note I am not saying just glue the two pieces together)

They are designed by the same manufacturer. They likely use the base and design it to be a GMT. It's not converted, as the ETA2836-2 is, but designed to be, and made from the factory as a GMT.

Yep. And in some ways, it's done better--the GMT wheel sits under a retaining plate, for example, so there's no issues with it lifting slightly and losing contact with its driving gear. However, in terms of concept, it's exactly the same--it's an additional wheel that sits on top of a movement which was not originally designed to have it, driven by the wheel that drives the calendar mechanism.

I dunno how they would turn a 2813 into a GMT movement, since it's a date only movement.   The modification to a 2836 relies on the day mechanism being used to drive the 24 hour hand.  

No, it uses the calendar drive wheel, which is present on both the 2824 and 2836. It's a slightly different part (on the 2824 it's integrated into the calendar plate cover thing while on the 2836 it fits on the mainplate itself) but there's no conceptual reason why you couldn't easily build a 2824 with GMT function in exactly the same way that the 2836 GMT works.

The day changing function is needed to adjust the hour hand though, so it would be non-adjustable if you did this on a 2824 unless you install the 2836 style double corrector.

They don't do converted 2813's , if you buy a 21j GMT , it has the 3804 in it already.  

A 3804 IS a converted 2813.

 But it might be worth opening the case to see if you have an eta movement

Based on the datewheel font, I'd bet it's an ETA.

I pretty much wanted to know if I was right about the case. Thanks

No, I don't think so--there's a lot more to the "clicking mechanism" than just counting the clicks.

Can someone tell me that the case is 100% correct based on the clicking mechanism?

I'm not sure why you're so hung up on this, but yes, a gen should click 120 times. Many reps do as well. Some older gens will not, quite, due to wear or damage to the bezel teeth and anything model 1680 or older doesn't click at all.

Why? Swapping markers is often easier, plus the markers on the newest dials have thinner surrounds.

You'd have to manufacture/fabricate/source all of the parts that make the 3185/3186 different from the 3135. That's much of the dial side of the movement. Unless they decide to clone them from the factory, I can't imagine being able to do it for less than just buying a 3185 would cost.

CLICKSPRING

 you get PMs by the thousand, asking for work or advise

Tell me about it. Every time I get a PM from someone asking me to work on their watch, I think of threads like this and usually say no.

It does fit, just checked yesterday. have one recently serviced by Domi I'm not using if anyone is interested.

I'm working on a jig to do this myself. I have a few gen dials, and a few ETA that I can use to see if I get the positioning right.

So you're thinking of using an ETA dial on a Rolex movement?

Mind if I ask why? Usually people go the other way around, since the dial is the part you can see...
