Believed to be a 1935 President with "Wandering Seconds.". Case is marked 10K gold filled, signed Bulova 4x: dial, case back outside/inside, movement. Case measurement: 29.80mm x 25.5mm, lug width: 13.11mm; lug to lug: 37.35mm; unsigned crown: 5.89mm; all measurements with digital caliper. Case was free of "brassing" (any indication in photos resulted from reflections). There is one very small area of "wear through" on a case back corner. The attached Hadley bracelet did not appear to match adverts sourced. The bracelet is apparently period correct and was marked: "Patent No. 1966063," patent issued July 10, 1934 (ref available). The history of this example is unknown. Upon receipt the watch appeared to work properly and has since been professionally serviced.
Wow, nice one! Interesting that s/n is only 6 digits and starts with a dash. There are examples in the Db with 6 and 7 digit S/N's - none starting with a "dash". There are 1934 and 1935 models in the Db with hinged cases, but I don't see any with 2 piece - curious. Perhaps a member with a more comprehensive knowledge of 30's Presidents can shed some light. Going by date code on movement, I agree:
1935 Bulova President

Thank you. Ref the "dash" (-) preceding the six digit SN and hope this is of help... I submitted a 1940 Commodore having a "dash" in June 2018 http://www.mybulova.com/watches/1940-commodore-9435 and did find another during research, 1942 President http://www.mybulova.com/watches/1942-president-8006.
I've included a better image of the SN for this submission.
