A rarely seen stainless steel Memovox "Jumbo" automatic alarm calendar watch from Jaeger LeCoultre, dating to c1960, in very good overall condition. The watch has an elegant classic case and an eye catching two tone "bull's eye" dial, in great condition with a sweep seconds hand and an alarm arrow marker on the inner section. The watch houses the rugged cal. 825 automatic bumper movement which is running strongly and keeping time with the alarm and calendar functions working perfectly. The crowns match. It is signed in three places, on the dial, case, and movement. As with all of my watches, authenticity is backed by a full money back guarantee.

Case: stainless steel, in great condition measuring approximately 38 mm across, excluding the matching crowns and 46 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 careful use but absolutely no signs of abuse, dents or significant scratches that I could see to point out to you.

Dial: two tone finish, black enamel with a white centre disc, in good condition, signed “LeCoultre Memovox Swiss”. Gold coloured Arabic numerals and batons mark the hours and the hands are in good shape. The crystal is clean and clear.

Movement: high grade 17 jewel automatic cal. 825 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 black leather strap which attached to the watch measures approximately 206 mm from buckle tip to last hole.
