Tennis player Medvedev Daniil spotted wearing a Bovet Fleurier

When Daniil Medvedev raised the US Open trophy at Arthur Ashe Stadium on September 12, 2021 — ending Novak Djokovic's bid for a calendar Grand Slam — the Russian wore one of the most technically complex watches in independent horology on his wrist. The Bovet Fleurier Ottantasei Flying Tourbillon, designed in collaboration with legendary Italian automotive design house Pininfarina, is not a watch that goes unnoticed, even in one of sport's most photographed moments.

The Ottantasei — Italian for 86, referencing the 86,400 seconds in a day — was unveiled as a landmark collaboration between Bovet 1822 and Pininfarina, marrying Swiss horological tradition with Italian industrial design philosophy. The 44 mm case, rendered here in blue-treated titanium, is transparent on six sides: front, back, and four lateral sapphire crystal panels that expose the full three-dimensional architecture of the movement. This construction allows the wearer and observer to view the flying tourbillon carriage, twin time-zone subdials, and the impressive gear train from virtually any angle — a display of movement architecture matched by almost no other watch in production.

The movement inside is Bovet's Calibre 11DM10, a hand-wound manufacture movement with an exceptional 10-day (240-hour) power reserve — visible via the "10 Jours" inscription on the dial. The flying tourbillon, positioned at 6 o'clock and beating at 18,000 vph, is constructed without an upper bridge, giving it a weightless, floating appearance that Pininfarina's design philosophy amplifies through the case's dramatic openwork structure. Dual time zones are displayed through two subsidiary dials at 10 and 2 o'clock, each with Roman and Arabic numerals.

For collectors, the Ottantasei occupies a rarefied space: it is produced in extremely limited numbers, with each configuration representing a distinct collaboration piece rather than a standard catalogue reference. The Pininfarina co-branding adds genuine design credibility beyond mere marketing — Pininfarina's engineers contributed meaningfully to the case architecture and ergonomics. The result is a watch that serious collectors regard as legitimately wearable sculpture.

Medvedev's choice to celebrate one of the greatest wins of his career with this particular piece is telling. The blue titanium colorway — matching his Lacoste match kit almost precisely — suggests deliberate coordination or an extraordinarily fortunate coincidence. At a retail price approaching $180,000, the Ottantasei positions Medvedev firmly among the elite tier of athlete watch collectors.
