I remember what I first answered you 'nah, not for me'.
Then when I saw it for the second time at the
24 heures Le Mans and got privileged to be entirely introduced to the concept, I cracked up twice. 1. because it is an extraordinary piece. 2. because usually I dislike the 3 buttons of a chrono because I do not often (never) make use of those.
This piece is (imo) simply amazing, it is a display of many modern techniques and features applied in a mechanical timepiece.
Way to go Jaeger LeCoultre! BRAVO!
and many more glorious hours to Aston Martin.
