Two tone case with a triple stamped movement - square shield, with lighter hand stamped "T" and "X" (1931, 32 and 33). Stamps are clustered next to the movement s/n and tough to photograph. Mounted on a later period yellow gold filled Foster scissor band.
No interior stamping indicating gold content, but case has an "F" stamped on one end between the lugs.
1933 seems to be correct and Kirkwood is what we have been ID-ing this case as. Referenced ad states 15 jewel, but I believe all of these we have ID'ed previousy are 17, like this example. Watch appears all original (except band and possibly hands) and still sports the original celluloid dust cover. Hands don't match 1934 ad, but match 2 other pre-1934 examples in the Db? Possibly a variance between "dress" and "radium" face?
Keeps time +/- a minute over 24.
