Montre Jaeger-LeCoultre Master Control date automatique acier bracelet cuir 40 mm

The genesis The Jaeger-LeCoultre Master Control collection was presented in 1992, but its aesthetics cannot be linked to a particular era and it has almost never evolved to the delight of its many enthusiasts. What hasn't changed Worthy replacement for the 1548420, this Jaeger-LeCoultre Master Control Date masters the codes of elegance even better. With its silver-white shades, minimalist design and refined details, this new version places the Master Control collection under the sign of elegance and sobriety. This three-hand date display is as fine, legible and elegant as ever. What's new What's new about this new version of the Master Control Date is that it's not obvious! This Jaeger-LeCoultre Master Control is equipped with the new generation caliber 899. While this movement is not new, it has been completely redesigned and incorporates new technologies. This caliber now has a new escapement and a silicon anchor, which minimizes friction and therefore consumes less energy. The central seconds hand has been redesigned to eliminate any wobble, and the balance fixing screws are made of titanium rather than steel for increased resistance. New lubricating oils have been used, specially formulated for these new materials. In order to increase the power reserve to 70 hours, the barrel has been completely redesigned to accommodate a stronger and longer mainspring without increasing the height of the movement (3.3 mm), a horological feat that watch lovers will appreciate. The whole thing fits into a steel case of 40 mm in diameter and only 8.8 mm thick! Our opinion If this version does not upset the codes of the Master Control line, it is interesting to observe that Jaeger-LeCoultre focuses on the mechanical updates that this illustrious Manufacture had to bring to its iconic pieces.
