Hesagraph RitmoCorsa

The Hesagraph RitmoCorsa is the flagship of the HTD collection: a Swiss Made hand-wound chronograph just 12.4 mm thick, with a timeless design that has already won over enthusiasts around the world. A special edition born from the partnership with the HTD RitmoCorsa racing team, celebrating five years of racing, victories and shared passion between watches and cars.

At its heart is a Swiss Made Sellita SW510 M hand-wound chronograph movement, with a 28,800 vph frequency and a tricompax three-counter layout. The 316L stainless steel case, 39 mm wide (48 mm lug-to-lug), is protected by an ultra-domed sapphire crystal and features a push-in crown with four sealing O-rings, for water resistance of 50 metres (5 ATM).

The true star is the special-edition dial: an enamelled base in an exclusive red, the very shade of the team's racing livery. Red, long associated with the world of motorsport, here reaches its maximum brilliance — as glossy as a freshly polished car body. Curved hands in natural steel colour complete an aesthetic that is at once clean and racing-inspired.

Like all HTD collections, the Hesagraph RitmoCorsa is assembled in Italy, in the brand's Florence workshop, in keeping with the city's watchmaking tradition.
