Bovet Pininfarina OttantaSei 10-Day Tourbillon Watch Hands-On Review
The most distinctive design feature of the OttantaSei (means “eighty-six” in Italian) watch is how the case looks and feels. At 44m wide and 12mm thick, the specs alone do not really communicate what this wide and proportionally thin case feels like on the wrist. Because the sides of the case are fitted with sections of transparent sapphire crystal, this feels so little like how most watch cases do. It feels more like a display cage for the movement contained within.
There are a total of four sapphire crystals on the case of the Bovet Pininfarina OttantaSei 10-Day Tourbillon, and the use of flat crystals on the top as well as the flat planes on the sides make the watch feel like a large coin on your wrist. Laser engraving is used on the sides of the case to print the “limited edition” and “Pininfarina” labeling, while the partial seconds indicator scale is printed on the one of the main crystals and read on the opposite side. Unlike some of the convertible Bovet watch cases, the Bovet Pininfarina OttantaSei 10-Day Tourbillon watch does not transform into a pocket watch, pendant, or desk clock. The case is water resistant to 30 meters.
Inside the Bovet Pininfarina OttantaSei 10-Day Tourbillon Watch is a new movement known as the caliber 17BM03MM. Manually wound, the movement operates at 18,000 bph (2.5Hz) and has a long power reserve of 10 days in one barrel. To view and operate the movement is real beauty. Bovet decided to keep things as simple and classy as possible by offering the time on a subsidiary dial, large-diameter tourbillon (which doubles as the small seconds indicator), and a power reserve indicator.
Design wise, the 17BM03MM movement of the Bovet Pininfarina OttantaSei 10-Day Tourbillon is a stunner, with dark-gray-finished plates and attractive texturing and finishing. All the Pininfarina watches have a decidedly modern edge to them compared to a lot of the classic or Old World, “artistically dense” design style that many people associated with Bovet.
