Hi All,

Wondering if anyone can enlighten me on the date of a Gruen wristwatch I have, Serial # 140678, Marked with Gruen Guild 15 Jewels Adj 4 pos, Caliber 157 (is this a Alpina?). Case is marked on the back with what looks like a WW symbol for Wadsworth ( I think) 10K Rolled Gold, nothing else on the inside except the serial number of the case# 5327664. I thought most of these were marked in the case as Quadron with Gruen Watch Co but this one is not.

Thank You To All,
Bila
