Jaeger-LeCoultre (JLC) 50635SQ Moon Phase Watch
Overview
The Jaeger-LeCoultre (JLC) Master Grande Tradition Tourbillon 50635SQ is a 42mm men's automatic watch with a white gold case and a clear analog dial protected by sapphire crystal. It uses a 876-440B caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 8 days when fully wound and will self-wind when moved.
The 50635SQ is currently ranked #313 in popularity out of 345 watches in this catalog. No retailer link is on file for .com; current availability is unknown. You can see other models similar to this one on the left side of the page. By clicking the checkbox under a similar model you can compare that model with this one side-by-side. We use nearly 100 different weighted criteria to calculate which models are the most similar to one another.
The case of the 50635SQ measures approximately 42mm wide (not including the crown) by 12mm thick and is water resistant to 50 meters. This should be sufficient for splashes, rain, baths & showers but is not recommended for swimming or diving. The white gold bezel is fixed (cannot be rotated). The gap between the lugs is 18mm and the leather band can be removed using a band removal tool to be replaced with another band.
