Identifying Accutron Transistors

I have recently gone down the rabbit hole of replacing all the bad components in my horde of accutron coils. I have already sourced the correct capacitors and resistors, but I am having issues finding what transistors were used on the 214 2 wire coils and the various different transistors used on 218 coils. From what I've gathered the 214 3 wire coils have CK722 or AY1117 transistors originally, and that a BC858A will work as a replacement.

Bulova Longchamp 1974

Hi, i inherited this watch from my grandpa. The only other example I've ever come across is on here too. Can anyone explain why I can't find any information on this watch, let alone another example? Is it possible these were limited run? I've hunted high and low but not really managed to find anything out about it. I've found other Longchamp watches from this era but they don't have numbers. Any info anyone has would be much appreciated or even point me in the right direction to find out a bit more about it would be great. Thank you in advance.

Can anyone suggest a repair service for my Accutron Spaceview II Kinetic.  First remake of the most famous Bulova Accutron 214 Spaceview. This model follows the same avantgarde style of the first model made in the 60`s, even matching the green color of the circuit board and back setting ring. Produced by first originator of the kinetic movements in Switzerland - Jean d`Eve

hard-to-find press down crystal

Hi Everyone:

I have a 1941 Watertight I recently purchased on eBay and brought back to life, identical to this one with the 10AX movement:  Bulova Models | myBulova.com

Does anyone happen to know the crystal it takes?.  It is one of those with the bezel ring that presses down around the crystal.

I recently acquired a similar crystal for another Bulova, but it was 28.3mm and was the 1112 E-1 crystal.  This one is a few mm smaller.

Hello all. New to the group. I have a 1930 Sylvette (my wife's) with a 6AP movement. It needs a new hair spring, but I can't find one anywhere. Is there a compatible one out there? I heard Breguet may be a possibility, but can't find any info. Any help would be appreciated!
