The Santos watch, in its medium model iteration, operates with a Manufacture mechanical movement featuring automatic winding, specifically the caliber 1847 MC. Encased in steel, it showcases a 7-sided crown adorned with a faceted synthetic spinel and a silvered opaline dial with steel sword-shaped hands, all protected by a sapphire crystal. Accompanied by a steel bracelet equipped with the "SmartLink" adjustment system, it also includes a second bracelet in calfskin, both with interchangeable steel folding buckles and the "QuickSwitch" interchangeability system. With a case width of 35.1 mm and a thickness of 8.83 mm, this remarkable timepiece offers water resistance up to 10 bar (approximately 100 meters/100 feet).
