Maen M8.1.1: Grand Tonneau Jump Hour Joins the Core Range
Maen is adding the Grand Tonneau Jump Hour to its permanent collection, with four dial versions priced at €719.20 before VAT, or €899 including VAT. The new range includes Steel M8.1.1, Anthracite Black M8.1.2, Midnight Blue M8.1.3 and Copper M8.1.4, with sales scheduled to start on December 10.
Hours that jump, minutes that rotate
The hour appears through a small window at 12 o’clock and changes in a single step at the start of the next hour. A separate rotating disc displays the minutes through the curved opening beneath it. Both indications are driven mechanically, leaving most of the dial free of hands or printed scales.
All four versions have vertical brushing. Steel retains a metallic silver appearance, while the black, blue and copper surfaces receive colored PVD coatings. The two-piece barrel-shaped case measures 34 mm across and takes its outline from tonneau watches of the early twentieth century.
The permanent collection follows Maen’s earlier limited collaboration with Nico Leonard. Alongside the different dial treatments, the new watches gain a display caseback, replacing the previous solid back and exposing a decorated movement with a custom rotor.
A modified automatic behind the windows
Maen modifies the Seagull ST1721 for the jumping-hour and rotating-minute display. The brand says each movement undergoes two weeks of testing before assembly. The standard black FKM strap closes with a steel butterfly clasp that combines micro-adjustment with perlage decoration.
- 316L steel case: 45 mm lug to lug and 9.7 mm thick.
- Sapphire crystal; water resistance: 50 m.
- Automatic movement: 20 jewels, 21,600 vibrations per hour and approximately 38 hours of reserve.

The listed starting price covers the black rubber strap; additional straps and the bracelet are priced separately.
