Crystal Part Number for latest Datejust (126XXX)?

[rmehandru]

Hi I am looking to replace a sapphire crystal on a 126234 Datejust. Can anyone confirm which part number I should be looking for?

Multiple watchmakers have told me different part numbers so I am conflicted. Any help is appreciated!

The crystal for model 126234 is part # 25/7035. This crystal is sold without a gasket. It replaced a variety of 25-295 crystals that were sold with various gaskets.

Ohh, I should also add that the crystal gasket is 29-295-6 should you need it.

Thank you for confirming that. Do you happen to know what the numbers following 7035 in the part number mean? For example: B25-7035-1-C1 vs B25-7035-4-C1

The number following the 7035 indicates the gasket, the C1 would be indicating there is 1 per package (Count / Content 1?) I believe all of the 7035 crystals are the same. I'm not sure which of those contains the gasket you need. Truth be told, I forgot there was a transition period between when the crystal was a 7035 & came with a gasket.

Ok and if I found a blister pack labeled B25/7035-J1 is that also compatible? This number system is not intuitive whatsoever.

Also When searching for gaskets, I'm having trouble sourcing a singular 29-295-6 gasket pack. Is there a way to find the height dimension of the genuine gasket? I may have to go with an aftermarket gasket with the same dimensions as the genuine gasket. Thanks again

I checked the new crystals in my cabinet today, and the packs are 25/7035-J1. I'm not sure what that indicates. The gaskets are 29.5mm diameter; I can check the height for you tomorrow.

Does anyone know if the crystal and gasket are the same for the 126200 (DJ 36 smooth ) and 126234 (DJ36 fluted)?
Thanks
