Jaeger-LeCoultre
Perhaps the most interesting and adventurous of all the major high-end watchmakers, Jaeger-LeCoultre, founded in 1833, has had an incredibly inventive history, developing over 1,249 mechanical calibres, registering over 400 Patents and playing a tremendous role in the development of the industry as a whole. Whether it is the keyless watch, calibre 101, the iconic Reverso or the Memovox alarm, it would be difficult to imagine a historical account of watchmaking without the mention of Jaeger-LeCoultre. The company has always been a true ‘Manufacturer’ of the finest quality watch movements. This is unusual because more often than not, high-end brands such as Rolex, Patek Phillippe, Audemars Piguet and Vacheron Constantin would often buy in movements for particular needs. For example, in 1967 when Patek Phillippe, Audemars Piguet and Vacheron Constantin needed an ultra-thin automatic movement, it was to Jaeger-LeCoultre they turned, to produce one for them. Furthermore, the exquisite Jaeger-LeCoultre Calibre 920, is still in production and in use today by both Vacheron Constantin and Audemars Piguet.
Description
The name ‘Memovox’ is composed of the two Latin words ‘memo’ and ‘vox’ which respectively mean ‘remember’ and ‘voice’. By most accounts, the Jaeger-LeCoultre Memovox came to the market in 1950 with the hand-wound Calibre 489 movement. However, in 1969 Jaeger-LeCoultre introduced the much improved high precision Calibre K916 automatic HF, an example of which we describe in some detail below.
The 1971 example here in 18ct yellow gold is sometimes referred to as the ‘Jumbo’ due to its very large 37mm, two-piece screw-back watch case. The two-tone silver dial is original, unrestored and untouched and has simply been gently cleaned to bring it back to the almost ‘as new’ condition you see here. Following some light polishing of the case and a full overhaul of the movement, this watch is now in tip-top condition and running and functioning perfectly. Naturally, it comes complete with its original JL signed winding crowns and JL signed gold-plated buckle.
The Dial
The original, unrestored and untouched two-tone silver dial is sensational. The dial is complete with a date function and carries original ‘stick’ style hands which are matched with applied black ‘baton’ batons. The shiny silver centre rotating disc, used for setting the alarm function, contrasts wonderfully with the yellow gold case. The slightly different tones of silver on the dial catch the light beautifully as we have tried to demonstrate in the photographs. As ever, the watch and dial look much better in real life.
As usual, Jaeger has done an excellent job of keeping the dial very clear and simple, considering the extra alarm function of the watch.
This dial is simply signed ‘Jaeger-LeCoultre’ at the very top, below 12, with ‘Automatic’ at the bottom just above 6, along with ‘Memovox’ and ‘T Swiss Made T’ at the very bottom.
Usually, we restore the dials of the watches we sell, however, we decided in this case to leave it alone, due to its exceptional condition and to retain its originality and charm for the many collectors who prefer this. It also helps to contrast with almost all of the other watch dials you see on our website which have been restored.
Please note, studio lights, professional-grade digital cameras, and macro lenses can be very unkind to an unrestored vintage watch dial. Also the dial here measures less than 1.25 inches across, so the image you see here may be between 5 – 25 times larger than the watch itself. Therefore please keep in mind you are seeing many tiny flaws which cannot be seen, or will be very hard to see with the naked eye, even under close examination. Suffice to say, on the wrist, in natural light, this dial looks much better and carries a great deal more charm than the photographs portray.
The Movement
Also known as a “Speed Beat”, the JLC Calibre K916 beats 28,000 at beats per hour for greater accuracy and resistance to motion. This was also the world’s first automatic alarm watch to use a rotor which rotates through 360 degrees. The added complication of a date function to this already unique, high beat, automatic, alarm, waterproof watch, elevates it to something really special. This movement was a milestone in watchmaking, the culmination of decades of history and technological improvements in watchmaking by Jaeger-LeCoultre. It was also truly successful, remaining in production for 20 years between 1969 and 1989 when it was eventually replaced by the JLC Calibre 919.
Jaeger-LeCoultre movements are amongst the highest quality and top tier of most highly regarded Swiss watch manufacturers. The movement used in this watch is the Jaeger LeCoultre calibre 916, which is a superb 17 jewel example of a classic automatic.
The movement on this watch is running and functioning perfectly. The alarm is wound and set with the crown at 2 o’clock. When the alarm sounds it is perfectly loud enough to hear without being too loud and one can also feel the alarm gently vibrating on the wrist. It will sound for 20 seconds, unless you wish to silence it immediately, by pulling out the same crown at 2 o’clock. This is very convenient since the alarm has its own alarm spring, which takes quite a bit of winding from its fully unwound state. Of course, if you only want the alarm to sound for around 5 seconds and for it not to be so loud, then simply wind the alarm crown to a quarter of its fully wound state.
This is the original movement, which as can be seen, is in sparkling condition having just been fully overhauled and serviced by our Master Watchmaker. This involves complete disassembly of the entire watch movement, close inspection of all critical parts under high magnification and then replacement where necessary, using only original manufacturer parts. The following stage is lubrication using individually specified lubricants for differing parts of the movement and careful re-assembly before regulating / timing. The watch winds and sets smoothly and is currently keeping accurate time, consistently, to within 8 seconds per day! This is outstanding for any vintage watch of this age. We therefore we have no hesitation in offering this watch with our 12 months warranty*.
This movement is signed ‘Le Coultre’, ‘Swiss’ and 916. The movement number Serial Number is 2121212 which dates the watch to 1971.
*Please note, our 12 months’ warranty is only applicable if the list price is paid.
The Watch Case
The heavy 18ct yellow gold watch case measures a large 37mm, excluding the correct twin Jaeger-LeCoultre signed crowns. It is of a two-piece construction with a heavy screw-down case-back.
Please note – although this watch was specified as waterproof when new, and even though the rubber seals have been replaced on the crowns and case back, this has not been tested and it is not guaranteed.
s ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.
The Strap & Buckle
The watch has been fitted with a high quality dark brown lizard strap with a gold-plated Jaeger-LeCoultre buckle. We think this contrasts very nicely with the pink gold case and the dial. However, if a different colour or style of strap is preferred, please let us know and we will do our best to oblige, free of charge. We carry tan, conker, dark brown and black in stock, in plain padded leather, crocodile skin or lizard skin and we can obtain most types and colours of strap from our partners at ‘Watch Obsession’ within 48hrs. Please take a look at their huge range of straps if you wish, here.
