To activate the minute repeater function, Jaeger-LeCoultre provides a pusher on the left side of the case. This is a notable difference from the traditional slide one expects on a repeater. The button also has a security system so that the user cannot re-trigger the repeater when it is already striking, which would run the risk of damaging the mechanism.
The Master Grande Tradition Minute Repeater is powered by Calibre 942, a 4-Hz movement with a 40-hour power reserve. It runs in 58 jewels; in total, it has 437 parts.
The watch comes on a brown alligator strap with a rose-gold pin buckle. It is water resistant to 50 meters. Price: $169,000.
