The basis for the Master Control watches was laid in 1946 when Jaeger LeCoultre (short: JLC) launched its first watch with an automatic movement. Not only the movement, but also the design of this first model has shaped the following watches. Master Control was only born in 1992 under a very exceptional corporate strategy. While other luxury watch brands rely on the demanding chronometer certificate (for particularly high accuracy) from the Swiss testing authority COSC, the JLC Master Control was subjected to an even tougher internal test procedure. Before delivery, each individual watch was subjected to a wide variety of tests over a period of 41 days and 16 hours. It had to withstand targeted shocks, magnetic fields, changing temperatures, etc. before it was sold. Thus, not only the movement, but the entire watch was put through its paces.

The Master Control is now available in various versions, such as here with a lunar calendar that shows the phases of the moon. Everything Worth knowing about the phases of the moon and well-known clocks with calendars is in our article. The model has a diameter of 39mm and a rather unusual lug width of 21mm.

The dark blue of the lunar calendar of the Jaeger LeCoultre Master Control can be combined very well with a blue strap. With the Dyster Blue Nato Strap the elegant watch looks modern and goes perfectly with a casual outfit with sneakers. On the other hand, it gains a particularly high-quality appearance with the matt red-brown Kopparmynt Brown leather strap.
