Jaeger-LeCoultre owns an unrivaled legacy of ultra thin watchmaking. Since the company’s first venture with Parisian partner Edmond Jaeger – the 1.38mm “Cal. 145” – wowed the world in 1907, ultra thin engineering has been a specialty of the manufacture from Le Sentier. This rose gold 40mm Jaeger-LeCoultre Master Ultra Thin takes tradition to the next level.
This generation of JLC Master Ultra Thin cases combine serious refinement with equal measures of substance. Less than 10mm thick (8.6mm, to be precise), the wrist presence of this watch is elegant but never quaint; a 39mm diameter ensures that nobody mistakes this modern marvel for a petite vintage bauble.
As a true manufacture, Jaeger-LeCoultre builds both the movement and the case that contains it; the benefit is engineering integration enjoyed by few rivals. Look no farther than the unusually robust 50-meter water resistance rating for the advantage of JLC’s in-house approach; most dress watches offer only 30-meter assurances.
Jaeger-LeCoultre’s caliber 896 features all of the hallmarks of a manufacture par excellence; ceramic rotor bearings; high-efficiency unidirectional winding; sub-4mm thickness, and laser-welded hairspring. It’s fine, slim, and still everyday tough; think Karen Allen in “Raiders of the Lost Ark,” and you get the idea.
The Jaeger-LeCoultre Master series took a huge aesthetic leap forward with the Ultra Thin model. The sports watch style lugs and massive proportions of the 2000s-era JLC Master cases often felt too massive an emotionally frigid for dress models. No more; the new Master Ultra endears itself to the user with an off-white eggshell dial and delicate 18-karat rose gold case that are as warm as hot cocoa at an Alpine ski lodge.
And JLC adds marshmallows; the applied rose gold indices, gulloche seconds subdial at six o’clock. Gleaming pink gold dauphine hands complete a picture of elegance that must leave JLC’s Richemont Group fellow brand Vacheron Constantin worrying about a black-tie turf war with its younger cousin from Le Sentier.
