Editor's Notes

Jaeger-LeCoultre's 'Master' timepieces are prized for their design complexities and ultra-thin cases. Crafted in Switzerland from stainless steel, this reference features a clean silvered-grey sunray dial with the label's signature blue steel seconds hand and a moon-phase aperture surrounded by 31 date markers. It's powered by an automatic calibre 925AA movement that's on display through the sapphire crystal case back and secures with a sleek black alligator strap.

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
