Another military watch to start the weekend...
Bulova A17A, USAF-issued navigator watch,
Parkerized steel case, 32mm w/o crown
caliber 10BNCH (hacking), Cold War era, circa 1959.
Seventh day wearing my calibre 355, date at 6:00 Seamaster, model 2627 NOS steel Omega case, and loving it! A phenomenal timekeeper after a thorough service.
