A 10 carat gold filled Memovox "Jumbo" automatic alarm watch from Jaeger LeCoultre, dating to 1957, in great overall condition. The watch has an elegant classic case and an eye catching two tone dial, in excellent condition with a sweep seconds hand and an alarm arrow marker on the inner section. The watch houses the rugged cal. P815 automatic bumper movement which is running strongly and keeping time with the alarm working perfectly. The domed crowns which are correct for the period, match. The watch is signed in three places, on the dial, case, and movement.

Dial: two tone satin silver finish in great condition, signed “LeCoultre Memovox Automatic Swiss”. Gold coloured batons mark the hours and the hands are in good shape. The crystal is clean and clear.

Case: 10 carat gold filled bezel with a stainless steel back, in very good condition, measuring approximately 38 mm across, excluding the matching crowns and 45 mm in overall length. The inside of the rear cover is signed "LeCoultre". This watch has been carefully looked after over the years, showing the expected marks from use but absolutely no signs of abuse, dents or significant scratches that I could see to point out to you. The back of the case which still shows the swirled engineering marks, has some light surface scratches, not obvious in the photos but which I mention for the sake of accuracy. They will easily polish out if desired.

Movement: high grade 17 jewel automatic cal. P815 bumper movement, running strongly and keeping time. The watch is set by the lower crown and the alarm is wound and set by the upper crown. Both functions operate correctly. The bumper unit is an early automatic movement which was first seen in watches in the late 1940's, with many LeCoultre and Omega watches housing them up until the early 1950's. The bumper version of the Memovox continued until the late 1960's as until then Jaeger LeCoultre had not come up with a way of stopping a fully rotational rotor hitting the pin on the inside of the cover, against which the alarm mechanism hits to produce the clicking sound when the alarm is activated. The bumper mechanism rotates through a little over 300 degrees, hits a stop and then bounces back and forth with a hammer action. If you look at the photograph of the movement you will see the springs which cushion the impact of the hammer action and send the rotor back over to the other side of the movement. As with most automatic watch mechanisms (the Futurematic is one exception), the movement can be hand wound. It should be "kick started" when first used by manually winding the watch. Older automatics are not as efficient as modern day mechanisms so the watch may, need manual winding from time to time, depending on how much use and movement it receives when worn, in order to keep the power unit charged.

Strap: fitted with a new brown leather stitched and lightly padded strap which attached to the watch measures approximately 212 mm from buckle tip to last hole.

This is a fabulous watch, manufactured by one of the most prestigious watchmakers in the world and in great condition. It is in fully working order, highly collectible as well as suitable for wear. Do not miss the opportunity to purchase this iconic vintage watch.
