The LeCoultre family traces its history in Switzerland to 1558, when Pierre LeCoultre immigrated from France, then moved to the Vallee de Joux the following year. All in all, it is a fun, attractive vintage watch that will continue to provide service for years to come. The silver dial has a sun-burst brushing that is still clear, with some yellowing around the perimeters from aging. Tritium paint was used for the lume, which still glows under UV light but fades immediately, suggesting that the lume is original to the watch. The one larger scratch appears on the side of the lug near 7 o’ clock. The case appears to be unpolished and shows light scratches as expected from a pre-owned vintage watch. The watch uses a monocoque case design, which means the movement can only be removed from the front by removing the crystal. The crowns, which are original to the watch, are thicker than some watches of the era, which makes them very functional. The alarm is set by puling the upper crown and turning it counter clockwise, which turns the inner portion of the dial that has the triangular marker.
The alarm is loud enough to alert the wearer without being so loud as to disturb your companions (although it will certainly attract their attention.) Lasting about 10 seconds, you will choose to respond or let it die out. The watch has two main springs, one each for the alarm and the time function. This Memovox is a versatile alarm watch, easy and fun to use, that has a vibrating hammer to sound the alarm. The Memovox is somewhat of a cult watch, which means you either know everything about it or you have never heard of it. Most were made for the American market, so the dials were usually signed only LeCoultre.Pre-owned Vintage Le Coultre Memovox Memodate 34.5mm, Silver Dial, Black Leather Strap with Tang Buckle, Ref.
