Editor's Notes

Jaeger-LeCoultre introduced its 'Master' line to focus on the most important element of all watchmaking: legible timekeeping - you'll notice the hour markers on this model are lengthened for improved readability. Expertly built in Switzerland, this aptly titled 'Ultra Thin' is designed in an elegantly slender profile and has a sleek 18-karat rose gold case complemented by an 'Eggshell' dial and dark-brown alligator strap. Equipped with a date window in the aperture of 6 o'clock, it's powered by a precise calibre 899/1 automatic movement that's exhibited through the crystal back.

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
