Duodecimal change
I find this timepiece extremely elegant with its copper dial and open heart... which doesn't reveal the balance wheel, as is usually the case, but rather a rather unusual mechanism... Indeed, thanks to this mechanism, the hour markers change every twelve hours to create a unique day/night indicator. This highly atypical complication, to my knowledge, was previously only found in Gruen watches. The version I am fortunate enough to own is limited to 200 pieces with this dial and is made of steel and titanium. Even though the watch required some repairs because the hour markers became stuck, it is now working perfectly again. The domed crystal enhances the elegant character of the model, and the original strap is suitable.
