This is the new Jaeger-LeCoultre Master Compressor Extreme World Chronograph. Perhaps the most technically impressive sport watch I've reviewed all year (and I've seen a few...). It's also a handsome piece, but quite the beast at 46mm in diameter. :o Retail price is $12,750.00. I'm not sure I'm ready to put my Daytona up for sale, and cough up another 3k to boot, but wow....really neat watch.
