Okay, here is my take on the Bivintage case my daughter ordered.
First up, if you have one of these you will need to remove the pendant tube and reinstall with loctite or similar as it is just sitting in there dry.
Second, you will also have to gently run a 1.2 mm drill bit through the lug holes as one side will be smaller than the other - I am assuming the manufacturers bit is slightly tapered from wear.
Now for the good stuff...nice case!
The crystal that came with it has a fracture and is a bit high, so I popped it and installed a Clark's T21 under a T21 bezel from 1016 lover on the forum which came in at .26 mm (.010") under the crystal on case, perfect fit.
The Bivintage T22 and Clark's T21 crystal measurements are:
Bivintage T22 30.70 mm
Clark's T21 30.55 mm
Bivintage T22 dome thickness 1.2 mm (.047")
Clark's T21 dome thickness 1.86 mm (.073")
Bivintage T22 depth
Clark's T21 depth
Bivintage T22 rim
Clark's T21 rim
Bivintage T22 internal diameter 29.29 mm
Clark's T21 internal diameter 28.84 mm
Which leaves the internal diameter of the Bivintage crystal .44 mm (.0175") larger than the Clark's which does not bode well for water resistance. Change the crystal!
Last but not least, use dishwashing liquid to lubricate the edges of the bezel when using the bezel removal press to save yourself some effort or scratches.
