It is a size 12. It measures 1.75 in diameter (including the case).
The watch sports 17 jewels, and I believe it is a Grade 910. It is 3/4 plate, and double roller. I believe it is gold filled.Runs perfectly - keeps time well. The crown is solid and firm. The original crystal was not clear, so I replaced it with a new crystal.
I just had the watch oiled, cleaned and overhauled. The chain is about 13.25 in length. All covers close tightly as they should. Inside the cover is stamped "GUARANTEED 25 YEARS" along with the numbers "339525". This watch is an exceptional value, considering the piece is nearly a century old.Ships only to the Continental U.
