The Speedmaster 125 was Omega's first officially certified chronometer chronograph. It was produced in 1973 in a limited series of 2,000 examples to commemorate the firm's 125th anniversary.

The unusual complications of this watch include a 24-hour register and a central 60-minute register, two rather exotic functions not previously seen on earlier Speedmaster models.
