The Watch: Jaeger-LeCoultre launched the Master Compressor in 2002 around a patented crown system that works by a half turn of a winged nut to close the crown, and that same turn back to open it. It's a simpler and more secure closer than a screw down, and easier to manipulate with a gloved hand. This ref extends that system to chronograph pushers as well.
The Chronograph 2 is the version running the cal. 751, Jaeger-LeCoultre's in-house automatic chronograph, 277 components, 39 jewels, 28,800 vph, with 65 hours of reserve off twin barrels. Every finished watch in the Master collection is run through the manufacture's 1000 Hours Control before it leaves Le Sentier.
The case is 42mm in steel, water resistant to 100 meters,
Condition: Good, some marks. See photos.
