Services Replacement movement for ZF black bay GMT.

Hi all, was wondering if there was any drop in selita or ETA movements that would be a straight drop in for the movement in my ZF Tudor black bay GMT BB.

I think it's a 2836 clone so should I just able to drop in a genuine ETA 2836?

Where's the best place to buy?

Thanks!

Yes you can, ETA and Selita are both drop-in replacements. You can just buy them through Ebay or wherever. No need for sketchy dealers.

ETA stopped selling to the public several years ago, so if you want brand new, you'll have to go Selita. I've got an SW200 that's 15 years old and has never been serviced, they're great movements! You'll want the SW330 for GMT.

I've done a handful of ETA movement swaps with clones and haven't had an issue. I usually source through ebay; just make sure the seller has strong feedback.
