Case measures 36.4mm x 24.4mm (not counting crown).
Kinda looks looks like one of those single hinged "flip backs" where you could put a photograph inside. The gold content is not marked. Case SN suggests 1932. 9A movement w/ 17 jewels in database as 1926, w/ a 15 jewel example in 1925. The movement serial number can be read upside down as 99608, but I'm assuming it was stamped in same orientation as other lettering.
