Indeed Raymond. This is an oldie but such a goodie as well. Many do not even know this Reverso was the 1st manual wind lateral clutch column wheel Chronograph which was not round but rectangular. JLC was truly making spectacular pieces back then 👍
Ay, this is a MAJOR catch, my friend. Huge congrats. A family picture has to be taken with the kings of the category, the Duometre, this one, the 1858 Tachymeter from MB, the A Lange Double Split and the Breguet 5247!
