The Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar is a stunning fusion of refined aesthetics and technical excellence.

A Legacy of Ultra-Thin Innovation
The Master Ultra Thin collection is a testament to Jaeger-LeCoultre’s pioneering role in ultra-thin watchmaking. This tradition dates back to 1907, when the brand introduced the LeCoultre Calibre 145, a groundbreaking movement measuring just 1.38mm in thickness—an extraordinary feat in precision horology.
Expanding on this legacy, Jaeger-LeCoultre introduced the Master Ultra Thin collection in the 1990s under the Master Control line, reinforcing its reputation for technical mastery and refined aesthetics. Over the years, the collection has achieved remarkable milestones, including the Master Ultra Thin Perpetual Calendar (2013) and the Master Ultra Thin Squelette (2015). Each of these innovations embodies the seamless integration of complicated mechanisms within incredibly slim cases, highlighting the brand’s ability to marry form and function.
In 2018, Jaeger-LeCoultre unveiled the Master Ultra Thin Moon Enamel, further demonstrating its commitment to blending artistry with cutting-edge watchmaking. This relentless pursuit of perfection solidifies its status as the "Watchmaker of Watchmakers."
