This newly invented calendar complication would lay down the foundation for a plethora of future models to utilize this functional and more-approachable calendar in terms of price point. Powering this watch is the Caliber 315 S QA 24H that impressively fits into a 37 millimeter case with a slim profile of only 11mm. The present timepiece has a very attractive configuration with a heavy platinum case, applied luminous Roman hour markers, and luminous leaf hands. The watch has a screw-in sapphire caseback which aids with water-resistance while showcasing the monumental movement.
