Looking for some replacement crystals for the SST with the rounded diamond shaped case (with or without logo).  This bad boy just arrived for restoration and the crystal shattered due to corrosion glue on the chapter ring and gasket  :yeller.  Case ref 882-976 or 883-976.  30.95mm width by 1.55mm thick.  Highly characteristic as to my knowledge this case design is unique to Zodiac.  Just in case, that is not a dirty dial, rather metallic blue speckled paint!  I thought it was flat blue based on the seller's photos...
