Servicing an early 1960's automatic LeCoultre Memovox Alarm Date calibre 825

I recently serviced this beautiful early 1960's automatic LeCoultre Memovox Alarm Date Calibre 825 watch for a ClockSavant customer. Once owned by his grandfather, it is both sentimental and a vintage watch of exceptional quality. The Memovox is arguably the finest mass production alarm watch ever made. A video posted to the ClockSavant Instagram page shows how well the alarm works when properly serviced. Combining automatic winding and the date, it is one of the most complicated regular production watches of the era, assuring their busy owner is on-time for important events, can see the date at a glance, and doesn't need to remember to wind the watch every morning. It is a  once-piece (monobloc) case meaning the movement is removed through the crystal. The stems are two-piece (split) and must be carefully force-fit into the watch. The watch has an automatic bumper mechanism wherein the weight swings between two springs creating a charming thump as you move your wrist. The time and date must all be synchronized correctly, via the many gears and springs, to assure the watches advances the date and sounds the alarm at the right now. A delicate calendar spring broke on the watch as shown in the picture. There are two mainsprings, one manually wound for the alarm and the other for the automatic. Running beautifully once again to within a few seconds a day, it's now keeping the family on-time once again.
