Jaeger-LeCoultre has launched the Master Control Chronometre collection at Watches and Wonders Geneva 2026, introducing three models — a Date, a Date Power Reserve, and a Perpetual Calendar — each featuring an integrated metal bracelet. The standout Date Power Reserve houses the new in-house Calibre 738 in a 39mm steel case just 9.2mm thick, with symmetrical sub-dials paying tribute to the 1951 Futurematic. The collection introduces Jaeger-LeCoultre’s new High Precision Guarantee (HPG) certification, which goes beyond standard chronometer testing by simulating daily wear conditions including altitude variations and temperature fluctuations. Watches are available in steel or 18-karat rose gold.
