Jaeger-LeCoultre Master Control

The Swiss luxury watch manufacturer Jaeger-LeCoultre presented the Master Control for the first time in 1992. It was their first wristwatch to undergo the then-new in-house testing process. Today, every Jaeger-LeCoultre timepiece must pass this test. Many other Swiss watch manufacturers rely on the Official Swiss Chronometer Testing Institute's chronometer test. Breitling, for example, sends every one of their movements to the COSC to be tested. At Jaeger-LeCoultre, however, the entire watch, rather that just the movement, is tested for its precision and resistance to pressure, shock, and magnetic fields. The test lasts more than 41 days, and this "1,000 hours control" process guarantees incredibly precise timepieces of the highest quality.

Jaeger-LeCoultre introduced the Memovox at the Basel Watch Fair in the early 1950s. The name of this early automatic watch with an alarm function roughly means "the voice of memory." But the Memovox doesn't only have an alarm function to wake you up in the morning, it also discreetly vibrates to remind you of appointments while it's on your wrist. If you set it down on a table or any other resonating body, its vibrations are more audible. A small hammer inside the watch is responsible for sounding the alarm.

A characteristic feature of the Jaeger-LeCoutlre Memovox is the presence of two crowns on the right side of the case at two and four o'clock. The upper crown is used to wind the alarm's barrel as well as set the date and desired alarm time. The other crown winds the movement and sets the time. Since the caliber powering this movement, the caliber 956, is automatic, the movement's barrel is automatically wound while being worn. Once fully wound, the caliber will run for 45 hours.

The Memovox is predominantly available in stainless steel or 18-karat pink gold. One highlight in this series is the limited edition stainless steel model with reference number 141848J. Limited to a run of 500 pieces, this retro watch with a blue dial has a design inspired by its 1970s predecessors and is thus a bit sportier than its siblings. Older retro watches were also the inspiration behind the luminous material on the hands and indices, making it easier to read the watch in the dark.

This special, limited edition model has a list price of almost 11,000 euros. Pre-owned, stainless steel standard models are significantly more affordable. You should be prepared to spend at least 4,500 euros on a pre-owned watch in good condition, and 6,500 euros or more on a new watch. Prices for pre-owned gold watches start at 12,000 euros and rise to 14,000 euros for new gold timepieces.

Business people often have to keep an eye on the time in various parts of the world – after all, you wouldn't want to wake up an important business partner with a phone call in the middle of the night. If you want to know the current time in any of the major time zones, the 24-time zone Master Geographic is the perfect Jaeger-LeCoultre timepiece for you. Using the second crown at ten o'clock, you can set the time for the second display. A display window at the bottom of the dial works in conjunction with a small arrow to indicate the second time zone you've chosen. The second time is displayed on a subdial above the six o'clock position.

Another subdial at two o'clock displays the date with an incredibly practical feature: the quick-set date, which is controlled by an integrated push-piece at two o'clock. All you need is a thin object to press the push-piece to activate the function. Across from the date display is the retrograde power reserve display. Once the movement is fully wound, it lasts for 40 hours. The Master Geographic comes in stainless steel or pink gold; a steel variant with a sector dial and skeletonized baton hands is also available. Due to the lack of date and power reserve displays, this version has a particularly clean dial.

Well-maintained and pre-owned stainless steel Master Geographics are available for around 5,000 euros; prices for pre-owned gold versions start at 8,000 euros. New stainless steel timepieces also cost around 8,000 euros and new gold versions cost around 16,000 euros.
