Here is a pic of grandpaws watch that was passed down to me. It has m3 on back which is a 1963 and seriel # is 407785. It is anti magnetic and shock resistant, and self winding. I dont think it has ever been serviced, however the number nine is upside down. I would really like to know how that happened because it doesnt look like it has been moved. It appears perfectly aligned. Would like to know what model,how much it cost new, how much its worth now and if a schematic or repair manual is available for it. Thanks E EDIT: Changed to Jet Clipper 2012/07/28
1962 ad for the 'JET CLIPPER' shows a Dial with the numerals placed in this position but not with the inward register, the Caseback also differs(?) slightly from any of the examples I own.

The 'SENATOR' shows a Dial with the Minutes register inboard of the Numerals as showing on Your Watch and is the only Dial I'm aware of off top of My head with this characteristic.
?
a stumper for Me personally 'til someone else chimes in.
a 1959 ad (ad 2) shows a Dial with the inboard register http://www.mybulova.com/sites/default/files/vintage_ads/bulova%20ad%201… so, although We do not have an ad confirming this exact configuration I'm 95% positive Your Grandfathers Watch is a 'JET CLIPPER'.
