Jaeger-LeCoultre Master Ultra Thin

Jaeger-LeCoultre Master Ultra Thin

The Jaeger-LeCoultre Master Ultra Thin reflects a careful balance between mechanical complexity and refined elegance.

Its 39 mm case, combined with a thickness of under 9 mm, gives it a particularly elegant profile on the wrist. Slim without feeling fragile, it carries a discreet presence suited to more formal settings while remaining perfectly wearable day to day.

The silver sunray dial is structured with precision. Small seconds at 6 o’clock, a date at 2, and a power reserve indicator at 10 are arranged in a way that remains clear and harmonious, avoiding any sense of clutter. Dauphine hands and elongated hour markers reinforce the overall sense of refinement.

Inside, the in-house calibre 938 delivers a 70-hour power reserve, visible through the sapphire caseback. It reflects Jaeger-LeCoultre’s approach to watchmaking, where technical performance is integrated into a restrained and elegant design.

This example is offered as a full set, brand new, with all original stickers still in place.

A piece that combines useful complications with a clean aesthetic, designed for those who appreciate subtlety and mechanical depth without excess.
