18K gold US-cased Observatory Chronometer with original hands, dial, and crown, despite a long service life and a crummy twist-o-flex bracelet. One of only about 670 such chronometers that G-P submitted to Neuchatel in 1966-67. Powered by the 36000 vph G-P 32A automatic movement.
This is off at G-P's Swiss headquarters getting its movement tended to. Fortunately, the spots below appear to be on the battered crystal, not the dial.
