Characteristics

Officine Panerai has for many years promoted the Panerai Classic Yachts Challenge, the most important international circuit of regattas for classic and vintage yachts. It has dedicated a series of watches to it which today have become cult items among collectors. To celebrate its special link with the world of classic yachts, Officine Panerai has created the P.9100/R calibre, the first Panerai watch with a function specifically associated with the world of sailing: the Regatta countdown function for the start of the race. The P.9100/R calibre is a development of the P.9100 automatic calibre with chronograph function. With its flyback chronograph with vertical clutch and column wheel, the P.9100/R is identical in architecture and diameter (13¾ lignes) to the P.9100 but it is a little thicker (9.55mm) and it has 26 more parts (328 altogether) as a result of the greater constructional complexity resulting from the addition of the Regatta countdown function.
