Appears to be a 1931 Bulova 'Sky King' with original MAXIM bracelet & presentation box. All are in excellent to mint condition. The only possible anomaly of the watch are the hands. They may be newer but it's hard to tell from the ads. There is no serial # on the movement & it has both a triangle & a square symbol (1935 & 1936) so may not be the original movement? The movement also has U.S.A. inscribed instead of 'SWISS'. The presentation box needs some work to get it functioning correctly. The watch winds, sets & runs.
Inside the case: BULOVA QUALITY - PAT. JAN. 11-1927 - 1083648
I've only seen a couple of these boxes in many years of hunting on eBay & was fortunate to acquire it at a decent price. I'll try to get it working this winter. I really like to get the original boxes & paperwork if possible so the watches can be displayed in all their glory. I mostly collect Hamilton's & Gruen's but Bulova's have probably the best & most colourful advertising, the largest variety of models, most models are named & their presentation boxes are the most diverse & interesting.
