Massive, charismatic, precise but still underrated timepiece built by Omega in 1974 to commemorate its' 125th anniversary. Back in that time, this watch was truly innovative and apparently a right choice to mark numerous achievements over Omega's history. The Mark 125 was the very first automatic chronograph officially certified as a chronometer in Switzerland. This particular piece has the reference 3780801 / 1780002 and is preserved in great condition - with a strong case and mint integrated bracelet showing little to no stretching. It features gorgeous black/dark gray dial with uniformly aged tritium markers and handset. 

Fully serviced in May 2018. Technical warranty: 1 year.
