Lee's Watch Thread for MM'ers of Impeccable Taste

[davej]

I've got a citizen nighthawk I'd part with, although I don't know if the crystal is sapphire, glass, lexan, or whatever. Says it's rated for 20Bar, so you know it parties.

Pictures?


Pulling out all my watches, need to replace batteries on a Seiko Coutura and a Buluva Marine Star.  Suggestions on DIY or just taking it to local watch shop?

Confirmed they are regular crystals though, not sapphire
