The collaboration between Reservoir and the Atelier de Plumasserie M.Marceau has resulted in the original strap of hand-woven feathers on calfskin, specially made for the Tiefenmesser Bronze Plume watch. Maxime Leroy, founder of the French company specialising in handcrafted feathers, has signed numerous collaborations in the fields of fashion (for Givenchy, Jean Paul Gaultier and Louis Vuitton), art, photography, film and design. The other features of the Tiefenmesser remain unchanged: the retrograde minutes, shown along a 240° arc, and the jumping hours, displayed inside the window at 6 o'clock, both on a white dial with blue details; a self-winding mechanical movement based on an ETA 2824-2 and an additional module produced by Reservoir, with a 37-hour power reserve; a bronze case, 43 millimetres in diameter, closed by a titanium back with a sapphire crystal porthole; and water resistance of 5 atmospheres. The watch comes with an additional Nato-type strap and is on sale for €4,590 (the Tiefenmesser feather strap is available separately for €480).
