With its cool, silvery-white color palette, minimalistic design and refined details, the Master Control Date anchors the new collection. Thanks to its slim movement, Calibre 899, the 40mm steel case of the Master Control Date is just 8.78mm thick. A Jaeger-LeCoultre mainstay since its introduction fifteen years ago, Caliber 899 has been repeatedly updated to incorporate the latest performance-enhancing technology.

Revised again for the new Master Control collection, the latest-generation Caliber 899 features a new escapement and pallets: reconstructed in a slightly modified shape, they are made of silicon to minimize friction and thus consume less energy. The central-seconds wheel has been redesigned to eliminate shaking; the fixing screws of the oscillating wheel are made of highly resistant titanium, rather than steel; and new oils, specifically formulated for the new materials, have been used. In order to increase the power reserve to 70 hours, the barrel was redesigned to accommodate a stronger and longer mainspring without increasing the 3.3mm height of the movement.
