JAEGER-LECOULTRE
Master Ultra Thin Réserve De Marche Automatic 39mm Stainless Steel and Alligator Watch, Ref No. Q1378420
Crafted at the Le Sentier workshop in Switzerland's Vallée de Joux, Jaeger-LeCoultre's watches are subject to 1,000 hours of rigorous testing until the brand's quality controllers are satisfied - it's this attention to detail that's earned the Maison the prestigious title of 'The Watchmaker of Watchmakers'. This 'Master Ultra Thin Réserve De Marche' model has an impressively slim case cast from polished stainless steel. The silvered-grey dial features refined dauphine hands that complement the angular indices, along with date and power reserve indicators, all the while maintaining a neat, simplistic appearance. You'll find that the leather-backed alligator strap grows increasingly supple with wear.
We offer an eight-year warranty for all working parts and manufacturing faults for Jaeger-LeCoultre watches. For more information, contact one of our experts by emailing watches@mrporter.com
