Most of the 56GS production process was automated beginning in the 1970s.
The precision level suffered as a result of this transition, with a decrease in movement speed from 36,000 bph to 28,800 bph.

5646-8000 is the Day/date model with pillowcase style, 35mm diameter.
The bezel and the sides of the case are polished but the lug sides of the pillowcase have a brushed finish.

The watch is a very good condition.
The crystal has slight marks but does not stand out.


Completely serviced by our watchmaker in May 2018.
Day/Date quick change is working perfectly.
Comes with 6 months warranty.
