Art Deco World has dated this piece to the 1930s.
Online records show the 7AP was manufactured from 1936 to 1944 and features a Breguet hairspring, as used on other high-end watches such as Rolex and noted for aiding more consistent timekeeping throughout the duration of the wind. This particular 21-jewel movement would have been one of Bulova’s top-of-the-range power plants of the era and is stamped with the moon date-code symbol for 1938. This also matches the date of the watch case itself.

The long, curved two-piece 10k yellow gold-filled case includes Art Deco filigree on either sides of the dial, extending to the tips of the lugs. It presents very nicely for its 84 years, showing the usual light surface use, but no obvious wear to the plating. The back is very clean, and it snaps on securely to the top. The outside is signed B-10K GOLD FILLED, plus its serial number starting with ‘8’. This indicates, on a Bulova of this era and with this particular movement, a manufacture date of 1938. The inside is signed BULOVA FIFTH AVE NEW YORK.

The movement has been completely disassembled and all components ultrasonically cleaned and inspected for damage and excessive wear. Freshly lubricated with the finest Swiss watch oils and grease, the beat and setting friction adjusted, and the timekeeping regulated.

Width: 20mm, excluding the crown.
Length: 35mm without the lugs; 45mm total length to tips of the lugs.
Thickness: 8mm, including crystal.
Face/dial: 14.5mm x 26mm.
Distance between lugs: 14mm.
Strap: XL Extra-long but narrow – 14mm wide at the lugs, tapering to 12mm at the buckle.
