Jaeger-LeCoultre Perpetual Calendar (until the year 2100) from a private collection, complete set. German month and day-of-the-week display Complete set: Outer box Inner box Service record (JLC, September 26, 2003) Proof of purchase (2004) Instruction manual The buyer will also receive the JLC watch stand and a dealer’s glove. To my knowledge, this manufacture movement is one of the smallest with a perpetual calendar. Power reserve 50 hours Unique adjustment via the crown only Important note: To avoid damaging the movement, it is extremely important to follow the instruction manual, as failure to do so may damage the movement. This watch was originally delivered by JLC with a gold-plated pin buckle (included) and has been fitted by me with an original JLC folding clasp in yellow gold. The value of the folding clasp alone is approximately 2,000 euros. Private sale with no warranty or guarantee; no returns. I have added another photo with the updated calendar. The movement does not need to be adjusted until March 1, 2100 (preferably by JLC) - deviation of 1 day every 122 years- The photos were taken with a smartphone, so the case and the folding clasp appear grainy. Both are smooth and flat like the case back and free of scratches or indentations (i.e., in very good condition).
