Omega Speedmaster Chronometer
The rare limited edition (of only 2000) vintage 1973 Omega Speedmaster "125" Automatic Chronometer commemorates the 125th anniversary of Omega in the seventies and is one of the largest, most substantial chronographs ever made. Not only is it an automatic chronograph, but it also carries the certificate of the Swiss Institutes for Official Chronometer Tests. This means that along with all the practical advantages of a true chronograph, the Speedmaster 125 has the uncompromising timekeeping efficiency of an official chronometer.
Nowadays, Chronograph-Chronometers with automatic winding are much more commonplace, but taking into account that automatic winding chronographs, considered the "last great complication to be achieved," were only introduced four years prior to the production of the 125 makes the feat all that more notable.
