**Master Compressor** is a model range by [[Jaeger-LeCoultre]].

===== The innovative Compressor Key System =====
With its compressor key system the [[manufacture]] [[Jaeger-LeCoultre]] invented a practical alternative to the conventional [[screw-in crown]] Even with a single half-turn of the compression key, the crown can be fully opened or closed; when closed, complete sealing is attained by the pressure on a cone located inside. Both states are clearly indicated by red and white arrows. So you do not have to remember, as with the old system, how tight you have to turn or to test back and forth until the screw engages.

In addition, the new solution, patented by Jaeger-LeCoultre, is also useful with [[manual winding]] watches in which previously screw-in crowns were mostly omitted and a better [[water resistance]] renounced. And, of course, the same applies for [[Chronograph]] pushers, where a significant improvement in handling is also provided. The design for the overall Master Compressor line was credited to [[Magali Métrailler]], Jaeger-LeCoultre's first female designer.

Since the first introduction of this invention, from the first models equipped with it a whole series of watches is derived, which includes sports models and also [[dive watch]]es, for women and for men respectively.

===== Success through persistent Focus on Excellence =====
After most of the JLC watches production was achieved through the classic [[Reverso]] not too long ago, the brand managed to provide an important additional pillar with the //Master Compressor// series. It scores particularly with the superior production quality of the models, ranging from [[manufacture]] movement to the good case processing to the self-confident and sporty appearance. There are plenty of offers on the market who are priced much lower, but a Jaeger-LeCoultre is and will always be something special. It permanently retains its value. Where other brands are trying to draw attention by loud PR campaigns, here always the watches themselves and their high production standards stand at the center.
