Engineered by SwissClone Certified Atelier for collectors who care as much about what's under the caseback as what's on the dial, the Jaeger-LeCoultre Master Ultra Thin Réserve de Marche 1378420 39mm Silver Dial Black Leather pairs a Solid 316L Stainless Steel (Satin & Mirror Finished) exterior (39MM (1:1 Factory Dimensions)) with the cloned 1:1 Cloned Swiss Automatic Calibre (28,800 vph) movement (48–70 Hour Power Reserve).



### Metallurgy, Crystal Clarity & Wrist Balance


The winding stem engages with a firm, positive click across every setting position, and the hands advance with zero backlash. Sealed behind a scratch-resistant sapphire crystal and triple-checked gaskets, it's built for daily wrist rotation rather than sitting in a display box.
