Jaeger-LeCoultre enriches the Master Control collection by introducing new interpretations of the signature complications in its collection — the Master Control Calendar and the Master Control Chronograph Calendar.
Now with interchangeable steel bracelets that are compatible with other strap systems of Jaeger-LeCoultre, the Master Control is more versatile than ever.
2022 marks the 30 years of the Master Control, launched in 1992 as a demonstration of the Maison’s commitment to the very highest levels of watchmaking excellence. The Master Control marked the beginning of the 1000 Hours Control system of internal quality standards at Jaeger-LeCoultre, a system subsequently incorporated throughout the full range of watches and which is now emblematic of the Maison’s fine watchmaking promise to its customers.
Two new Master Control models, in stainless steel with interchangeable bracelets, bring the calendar display and chronograph function more fully into contemporary everyday life, recognising the prominence of active lifestyles in the world today.

Building on the recent success of the JLC Master Control Calendar watch with blue dial, the latest Master Control Calendar with interchangeable bracelet comes in a dial colour palette that focuses on purity and refinement.
The silver sunray-brushed dial features a tone-on-tone aesthetic, maintaining the essential design codes of the Master Control such as dauphine hands and Arabic numerals intercut with dart hour markers.
The jumping date hand that characterises this model is endowed with a red-lacquered indicator tip in the shape of the Jaeger-LeCoultre logo, allowing the date to be read easily and intuitively.

The Master Control Chronograph Calendar features blue chronograph hands and a blue moonphase disc to bring out the indications of the complications.
For the first time, both the Master Control Calendar and the Master Control Chronograph Calendar are available on a steel bracelet with a quick-change system.
Both the new Master Control models with steel bracelet also come with a light-brown strap in Novonappa® calf leather.
These leather straps are equipped with the same quick-change system, allowing the Jaeger-LeCoultre Master Control to truly become a watch for all seasons.
