In 2008, Jaeger-LeCoultre celebrated their 175th Anniversary with the Memovox International, in stainless steel or rose gold, the Tribute to Polaris 1965, in stainless steel or platinum, and the Tribute to Polaris 1968. Watches with this movement included the base Memovox, the Master Compressor Memovox dive watch, and the Master Compressor Extreme W-Alarm, which uses the similar Cal. In 2003, the calibre was again updated, becoming Calibre 956. This was used in the Master Réveil, Master Compressor Memovox, and the AMVOX 1. Additionally, an automatic movement without the perpetual calendar, Calibre 918, was also introduced. The hand-wound Memovox was the first with a transparent sapphire case back, allowing the owner to watch the alarm function in action.

The manual winding Memovox was updated in 1994 with the gong, becoming Calibre 914. Van Cleef & Arpels “Memodate” used Calibre 911 and included a timezones bezel. Calibre 911 added a date window and was produced in greater numbers, lasting in production until the 1980's.
In North America, Vacheron Constantin LeCoultre, a subsidiary of Longines-Wittnauer, handled final assembly and distribution, so some differ in case and dial detailing.Ĭalibres 910 and 911 were introduced in 1964, replacing all other manual-winding Memovox movements. Until 1980, all Jaeger-LeCoultre models, including the Memovox, were sold as “LeCoultre”, and many cases were locally produced as well. Memovox watches were also sold by Cartier, Gubelin (called “Ipsovox”), and Van Cleef & Arpels. Jaeger-LeCoultre also introduced shock protection to these movements, resulting in the Parachoc-equipped Calibre P489 and the Parachoc or Kif-equipped P814 and K814. A short run of less than 2,000 Calibre 601 models was followed by the 1953 introduction of Calibre 814, which featured a date display and was much improved for servicing and reliability. Jaeger-LeCoultre's Calibre 489 was quite successful, but the company quickly began work on a successor. In hand-wound Memovox models, the alarm spring is wound using the upper (2 00) crown, which also sets the 12-hour alarm disc and activates the alarm. The Memovox movements have always had a separate mainspring for the alarm. One innovation from Jaeger-LeCoultre was the separation of the power reserve for the timekeeping and alarm functions.
Intended to compete with the 1949 Vulcain Cricket alarm watch, the first Memovox models were manually-wound. Shortly thereafter, the company introduced the “Memovox” brand, and this has continued since then. The first Jaeger-LeCoultre alarm watches were introduced late in 1950 and used the brand, “Wrist Alarm”.
