Details & Specifications
Description:
The Jaeger-LeCoultre Master Control Chronometre Date reference Q4158120 embodies contemporary elegance in a refined 38mm stainless steel case measuring just 8.4mm thick. The blue-grey gradient sunray-brushed dial is set with polished rhodium-finish Dauphine hands, dart-shaped indices, and Arabic numerals at 12, 6, and 9 o'clock, complemented by a framed date window at 3 o'clock. The integrated three-row stainless steel bracelet blends brushed and polished finishes, with V-shaped bevels echoing the geometry of the hands and indexes. Powered by the automatic Manufacture Calibre 899, the movement delivers a 70-hour power reserve at 28,800 vibrations per hour, with precision certified by both COSC and Jaeger-LeCoultre's own High Precision Guarantee (HPG) Seal, which tests the fully cased-up watch under real-life wear conditions.
This example is brand new, from 2026.
