I don't know which brand made the first Wristwatch Perpetual Calendar, and I didn't mean it was U.N.

I just said that the perpetual calendar released by U.N in 1996 was really revolutionnary, as it was the first TO ALLOW the owner to set the date forward, and backward.

It would be interesting to know who invented the first PC....Necessarily a pocket watch, but I don't know who...

Best,

Nicolas
