Jaeger LeCoultre Memovox
This is a gentleman's stainless steel Jaeger LeCoultre Memovox ref 855 in lovely original condition with mechanical alarm in perfect working order - sounding loud and crisp. This is the much rarer large or jumbo 37mm sized version of the Memovox and is an automatic with date function.
The Memovox range is a signature Jaeger-LeCoultre model and one of the icons of 20th century wristwatch design. Over the decades the Memovox has been styled with a variety of different case and dial designs.
The is an example in a classic Memovox design with a relatively large case, measuring 37mm in diameter. The bold, linear dial has gently tapering indexes which are centrally set with black inserts; the straight baton hands are styled to match with centralised luminescent tips mirroring the luminescent panels set at each hour within the track for minutes/seconds. To the dial centre, the alarm setting disc is finished with a circular satin grain which gives the dial a two-tone appearance – in fact, as the track for minutes/seconds is chamfered inwards it creates the illusion of a 3-tone dial, the eye perceiving three different dial finishes as it catches the light.
Two Jaeger-LeCoultre crowns are set to the case side, the upper is for winding the alarm barrel and setting the central disc to the alarm time, the lower crown can be used for manually winding the watch if it is completely out of power and also for hand-setting. There is provision for semi-quick date change – the date will change each day around midnight but can be manually advance when required by moving the hands repeatedly between
