Hands-On A. Lange & Sohne Langematik Perpetual Limited Blue 2021
When A. Lange & Sohne unveiled the Langematik Perpetual in 2001, it was the first mechanical wristwatch to combine a perpetual calendar with Lange's signature outsize date. Revisited in different case materials over the years, the 20th anniversary of the Langematik Perpetual is celebrated with two models, one in white gold the other in pink gold, both with a striking blue dial and limited to 50 pieces each.Just seven years after Lange's resuscitation in 1994, the Saxon watchmaker launched one of the finest perpetual calendars on the scene today. Flexing its horological muscles, Lange's perpetual calendar stands out from other calendar watches with its patented zero-reset mechanism and corrector to advance all the calendar displays simultaneously. The perpetual calendar functions account for the different durations of the months, including leap years and, once the watch is correctly set and kept ticking, you won't have to adjust the date display until 2100.

The dilemma of Constant Force in Watchmaking - Monochrome Watches
Constant force is a holy grail of watchmaking and chronometry. The varying driving force delivered to the regulating organ of watches affects their rate, because balance wheels are not perfectly isochronous - isochronous means that the period of oscillation is independent of the amplitude of oscillation. Modern barrels and the Swiss lever escapement offer satisfactory regularity. Still, in their ongoing search for precision, watchmakers are showing renewed interest in taming power even further. Here is our technical guide to the complex concept of constant force.The barrel is the device that stores energy in a watch movement. It contains the mainspring coiled around the barrel arbor, which is put under tension to power the movement. The force delivered by the barrel is irregular. Strong torque is provided when it is fully wound, then it slowly wanes throughout the power reserve duration. This affects the rate of watches because balance wheels are not perfectly isochronous. The period o

Pre-SIHH 2014: Jaeger-LeCoultre Duometre Unique Travel Time in Rose Gold - Monochrome Watches
When it comes to watches that can indicate time in your own timezone and an additional timezone, you will find there’s a whole world of choice out there. However be aware that you choose one that suits your requirements. There are traveler GMT watches, office GMT watches and worldtimers, all with their own limitations. Except the Jaeger-LeCoultre Duometre Unique Travel Time, which makes it possible to adjust the second timezone to-the-minute. Most worldtimers are build to indicate the time in 24 different timezones around the world, however some nations felt the urge to create an additional timezone and with that they also created a problem for the watch industry. Creating a worldtimer with a ring that rotates once in 24 hours, isn’t going to help for people traveling to Iran (GMT+3.5), Afganistan (GMT+4.5) or India (GMT+5.5). Want to visit Birma? You will have to adjust your worldtimer to GMT+6.5 hours and still keep your hometime at the correct time at home. Vacheron Cons
