Sorry I am sold

A rarely seen stainless steel Memodate "Jumbo" automatic alarm calendar watch from Jaeger LeCoultre, dating to c1970, in superb original un-restored condition. It houses the cal. 916 movement with the fully bi-rotational winding rotor. This watch has been in my collection for some time as I rarely come across a watch in such great original condition and I wanted to enjoy wearing it before selling it to make way for new additions. It has an elegant classic case which looks great and an attractive un-restored dial with a sweep seconds hand and an alarm arrow marker on the inner section. The movement is running strongly and keeping time, with the alarm and calendar functions working perfectly. It is signed in three places, on the dial, case and movement.

Case: stainless steel, in great condition measuring approximately 37 mm across, excluding the matching unsigned crowns and 43 mm in overall length. The inside of the rear cover is signed LeCoultre. This watch has been carefully looked after over the years and probably only worn occasionally. It is showing the expected light marks from careful use but absolutely no signs of abuse, dents or significant scratches that I could see to point out to you.

Dial: original factory satin silver finish, signed “LeCoultre Memodate Automatic Swiss”. Applied rose gold coloured batons mark the hours and the hands are in very good shape. The crystal is clean and clear.

Movement: high grade 17 jewel automatic cal. 916 movement, running strongly and keeping time. It is a high beat movement, running at 28000 A/h compared with 18000 A/h for the previous cal.815/825 bumper models. This provides for greater accuracy in timekeeping. The 916 was the first automatic alarm watch produced by any watchmaker with a rotor that would turn a full 360 degrees. Previously they always housed a bumper mechanism due to the alarm hammer mechanism which, when activated hit a pin protruding from the inside of the back case cover. The bumper rotor swung back and forth without hitting the pin whereas a fully rotating rotor would hit it. This problem was ingeniously overcome with the 916 by the alarm pin on the case cover passing through a hole in the centre of the rotor. If you look at the photos below you can see the pin on the inside of the cover. The watch is set and can be wound by the lower crown and the alarm is wound and set by the upper crown. The calendar function operates correctly. The serial number on the movement dates the watch to c1970.

Strap: fitted with a generic brown leather strap which attached to the watch measures approximately 220 mm from buckle tip to last hole.
