For your consideration is this manual winding vintage men’s wristwatch movement that is running for repair. The movement runs for a couple minutes before stopping, and the stem detaches after the mainspring winds to a certain tightness. The Swiss movement was made by Bulova in 1956, and it is the caliber 11ACC “Commodore” model featuring a nice round 10K yellow rolled gold plated bezel and a stainless steel snap on back. It also features a nice white dial with a gold-tone pencil-shaped hands pointing to bar & even numeral markings. The 17 jewel movement case measures 31mm in diameter, and the fancy lugs have an inside measurement of 16mm. The crystal is worn, but the dial is very nice. The crown is not matching for this movement, but one springbar is included and attached. Please see pictures for more detail, and feel free to ask any questions!
