Jaeger-LeCoultre (JLC) 5042520 Moon Phase Watch
Overview
The Jaeger-LeCoultre (JLC) Master Grande Tradition Tourbillon 5042520 is a 42mm men's automatic watch with a rose gold case and a silver-white analog dial protected by sapphire crystal. It uses a 985 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 45 hours when fully wound and will self-wind when moved.
The 5042520 is currently ranked #296 in popularity out of 345 watches in this catalog. No retailer link is on file for .com; current availability is unknown. This watch is part of a family of five watches that are identical except for their color or strap. You can see the other variations in this family as well as other similar models 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 5042520 measures approximately 42mm wide (not including the crown) by 13mm 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 rose 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.
The 5042520 provides the following features and complications:
- Seconds subdial
- Minute hand
- Hour hand
- Day subdial to show the day of the week
- Date subdial to show the day of the month
