The precision level suffered as a result of this transition, with a decrease in movement speed from 36,000 bph to 28,800 bph. The watch is excellent condition. Date quick change is working perfectly. Warranty Completely serviced by our watchmaker in August 2019. The case is polished, and gaskets, crystal glass, and calendar parts are replaced in the last service.
