The extract says September 16 1977.
I have a October 21st 1976 (per extract) that I was thinking about selling earlier this year, but after having it serviced last month decided it's running too well to sell now. Last time I checked it only gained 0.5 seconds in 6 days from 8/19 - 8/25/19.
Original dial, hands, bezel, case, and 1171 bracelet. Mainspring was just replaced, and cyrystal was replaced with an Omega signed hesalite at a previous service since the old one was cracked. No idea about pushers and crown which used to be replaced routinely for improved WR, but they didn't need to be replaced on the last 2 services since I've owned it.
