I’m selling this GP HF chronometer from 1968. CASE: 37,5mm excluding crown, gently polished in the past but still with sharp edges, the radial brushed finish is visible. The original GP crown has a spot where the superficial part is missing (please see pics). The bracelet shown is not original GP. DIAL and HANDS: original silver dial with vertical brushed finish, has some light patina visible only on certain angles and on the outer ring. MOVEMENT: high frequency 42.1 series movement, it is marked “36000 a/h 421797” and “Girard-Perregaux 39 thirtynine jewels gyromatic swiss” on the rotor. Service history unknown, the seconds hand sweeps super smoothly as expected and it keeps accurate time. I'm asking 600€ (was 680) plus shipping, the watch is located in Italy, here are my references on OF: https://omegaforums.net/threads/spruce-is-a-great-buyer.104405/#post-1366893 https://omegaforums.net/threads/franz-great-deal.36727/ https://omegaforums.net/threads/franz-is-a-great-seller.79804/ https://omegaforums.net/threads/franz-is-an-amazing-seller.79954/ https://omegaforums.net/threads/franz-is-an-excellent-seller.104330/ https://omegaforums.net/threads/good-guy-franz.97365/ https://omegaforums.net/threads/franz-is-a-great-seller.113452/ https://omegaforums.net/threads/perfect-deal-with-franz.112900/ i'm obviously happy to answer any questions.
