Tudor/ETA 2750 Stem

[MattWatch]

So i just picked up a stunning old Tudor, minus the crown! I believe this has the ETA 2750 movement.

The stem seems quite short to me. Fitting another crown there is not enough "travel" to fully insert them stem when it's re cased. So I'm thinking the old crown may have snapped off?

Anyway, main problem - buggered if I can get the stem out! I assume it's the little button near the stem but pushing on it won't release it and I'm terrified of pushing too hard and pushing the button out the dial side.

Any ideas please?!? Am I heading in the right direction with that being the correct stem removal procedure?

Ta, Matt

You won't push the button out dialside as there are parts over it. But you could disengage parts in the keyless work so it's gets hard to put the stem back into place again. It's the right button so need to press on it to get the stem out. If it doesn't work take the hands and dial of.

Thanks for this. Ok, odd, using a flat blade screwdriver I can actually feel the button depressing but the stem will....not release. I wonder if there's a problem somewhere within?

Choose the LARGEST HEAD screwdriver to go through the hole B-B, push down on the button as you like, the screwdriver stops at a point, by a step, provided as the diameter of the hole A-A  the button is in, is smaller. The step is as deep down the botton is to go to release the stem.

The key to proper, risk free operation is the SIZE of the scrwdrivers head, to be larger than the diameter of the small holeA-A,  just so it can,t get inside the smaller diameter hole.

Modified to show the screwdriver head/tip.

You can work with a smaller screwdriver or any tool, as long as, it dosn,t enter the smaller hole.

In case the stem dosn,t want to come out, rotate them stem, a slight pull wont hurt. 

Keep us posted please.

Goodness! That's what I call a thorough response. With diagrams no less! Outstanding sir :)

I'll have another look later and see where we are.  Thanks so much.

I fell in love with this tudor.

Getting  charged a fortune on one hand and risk getting this beauty damaged. So I suggest do not use a flat blade screwdriver, but a round bar, hard strong polymer stick, it would be worth the trouble of cutting one out for the job. Polymers wont scratch the surface.

Once the button is pushed as far down as the designers calculated, you may need to push/pull the stem in and out, turning the crown can help.

Though stem extender is normally used, you wouldn,t want anything less than perfect for such a jewel.

Thanks also for this, much appreciated.

As you seem to be a fellow fan, here's a couple of pics of it cleaned up, screwed together with a temporary crown on it. It's a beauty.

There's a slim chance of me conceding on this one and taking it to my watch guy, in part for some of the reasons mentioned in this thread!!

Glorious indeed. The sunray dial glittering is my favourate.

Wise decision to entrust it to a master watchmaker.

Best wishes
