OMEGA

Speedmaster Mark 4.5

ref. 176.0012

Vintage Lemania 5100 Automatic Chronograph

Beautiful 1970s Classic

This  beautiful early 1970s Classic chronograph in very good running condition – it has been recently serviced and both watch and chronograph work as should.

The stainless steel case is in good condition with just one small dent, and the dial with large chrono sub-dials and hands are all in original, perfect condition.

The 5100 is quite famous and has some interesting complications. While it might look like a Valjoux 7750 at first glance, the 5100 uses the central dial for counting both the seconds and the minutes, while the movement also has a synchronized 24 hour indicator the helps with military time and serving as a day/night indicator
