Jaeger LeCoultre Cal. P812 Bumper Automatic 1960s

A masterclass in mid-century elegance and horological – innovation.Jaeger-LeCoultre Cal. P812 Bumper Automatic

This stunning Jaeger-LeCoultre from the 1960s embodies everything that defines the golden era of Swiss watchmaking: technical precision, restrained design, and timeless proportions.

At its heart is the Caliber P812, an early automatic bumper movement, cherished by collectors for its mechanical charm and historical importance. The soft hum of the bumper rotor recalls a time when automatic technology was still a refined novelty — and JLC was at the forefront.

The 35 mm stainless steel case flows effortlessly with integrated lugs, while the silver dial with subtle minute track reflects light in all the right ways. Clean, balanced, and quietly sophisticated.

Whether worn daily or reserved for special occasions, this piece delivers on all fronts: heritage, wearability, and timeless appeal.
