Patek Philippe Ref. 2499 (Lifestyle)
September 24, 2024
The Patek Philippe Reference 2499 is a perpetual calendar chronograph that was produced by Patek from 1950 until 1985. The model is extremely limited with Patek only producing an estimated total of 349 units during that 35 year period (10 units per year).
Features of the watch include a perpetual calendar, chronograph, and a moon phase. The perpetual calendar complication is used to display the correct date with automatic adjustments for the varying lengths of months, including leap years. The chronograph is used as a stopwatch to measure elapsed time by using the pushers to start, stop, and rest the measured time. The moon phase is used to track the phases of the moon over the period of the lunar month. The combination of all three of these complications makes for an extremely complex watch movement, and is referred to as a “grand complication” in the world of horology.
In recent years the 2499 has sold at auctions anywhere between $2 to $5 million for gold models, and well over $10 million for the more limited platinum models.
