Following a successful collaboration with Nico Leonard, Maen bring the Grand Tonneau Jump Hour to its permanent collection, with four new dial colours and a slightly more accessible price.
Jumping hour watches have enjoyed a recent rise in popularity. Still, they remain a relatively unusual proposition. Maen has found an audience for this alternative way of displaying time. In 2025, the Stockholm-based brand teamed up with content creator Nico Leonard to introduce a limited-edition Jump Hour. Encouraged by the success, Maen now brings the design into its permanent collection with the Grand Tonneau Jump Hour. The new model retains the collaboration’s essential construction, including its tonneau-shaped case and jumping-hour display, but adds a few changes.
A case mixing vintage cues and modern execution
The Grand Tonneau Jump Hour comes in a two-piece 316L stainless steel case measuring 34mm wide, 9.7mm thick, and 45mm lug-to-lug. Its barrel-shaped case features a combination of brushed and polished surfaces for a layered, architectural appearance. Sculpted lugs rise above the dial and follow the contours of the integrated strap, while the overall profile remains quite slim. The case features a sapphire crystal with an anti-reflective coating and a display caseback, a welcome change from the solid back of the collab edition. Water resistance is rated at 50m.
New colours, new finishes
As its name suggests, the main attraction is the jumping-hour complication, which gives the Grand Tonneau its identity. The hour is displayed numerically through an aperture at 12 o’clock. The numeral changes instantaneously at the beginning of each new hour. Minutes are indicated on a rotating disc, visible through the curved window below the hour aperture.
Four dial versions become available, and all feature vertically brushed surfaces. Steel offers a clean metallic appearance; Anthracite Black, as photographed here, is darker and more contemporary. Midnight Blue introduces a deep blue tone, and Copper is the warmest option, with a salmon-like presence.
A modified Seagull Jumping Hour movement
The watch is powered by the automatic Seagull ST1721, modified by Maen to operate the jumping-hour and rotating-minute displays. It contains 20 jewels, runs at 21,600 vibrations/hour and provides an approximately 38-hour power reserve. Maen also says that every movement undergoes two weeks of in-house testing before assembly. The movement is now visible through the sapphire caseback, where a custom rotor adds a more personal touch.
The Maen Grand Tonneau Jump Hour is worn on a black FKM rubber strap, closed with a stainless steel butterfly clasp, decorated with perlage and fitted with micro-adjustment. An orange FKM strap and a bamboo steel bracelet are optional extras.
Availability & Price
The Grand Tonneau Jump Hour joins Maen’s permanent collection and will be on sale from December 10, 2026. It will be priced at EUR 899 including VAT, down from EUR 999 for the collaboration with Nico Leonard. For more details, please visit www.maenwatches.com.
