Editor's Notes

Jaeger-LeCoultre launched its first 'Calendar' watch in 1945 and added the 'Master' edition to the range in 2013. Powered by an in-house calibre 866/1 automatic movement, this reference is engineered with highly legible complications, including a date hand, day and month windows and moon phase sub-dial. The sleek stainless case is a nice complement to the silver sunray dial, while the brown leather strap makes it suitable for everyday wear.

We offer an eight-year warranty for all working parts and manufacturing faults for Jaeger-LeCoultre watches. Call our Customer Care team for more information.
