Editors’ Notes

The words "master" and "ultra thin" belong together in the realm of haute horlogerie, where creating a slender watch that's visually and functionally flawless is a feat of the highest level. Handcrafted at the historic workshop in Le Sentier, Switzerland, Jaeger-LeCoultre's automatic watch has a moon-phase complication showcasing the time of day across its dial, and is encased in 18-karat rose gold. The uncluttered design will age beautifully, as will the 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 myshop@net-a-porter.com

Wear it with: Brandon Maxwell Pants, Prada Polo Shirt.
