MAEN × Nico Leonard Grand Tonneau Jump Hour Black

Released in 2025 in collaboration with watch YouTuber Nico Leonard, the MAEN Jump Hour is a modern take on one of the most romantic and classical of complications.

The case is crafted in steel and measures in at 34mm x 45mm, which endows it with wrist presence without overstepping the boundaries of what you'd expect to see when housing a complication such as a jump hour. The case itself is a tonneau-tank hybrid, with polished lugs with abroad bevel extending uninterrupted from end-to-end, within which sits a vertically brushed inner section which then houses the dial. The dial itself is deep black in this variant, and very sparse, allowing the complication to be the star. 

Powering it is an automatic movement based on the Seagull ST1721 caliber, modified to suit their requirements, and it's mounted to an FKM rubber strap with double deployant.

This particular example was delivered in December 2025 and presents in TZ 'Good' condition. The polished sections of the case show light scratches, and the reason for the 'Good' rather than 'Excellent' grading according to the TZ scale is due to a couple of small pin dents on the left side of the brushed inner section, and a tiny nick on the left bevel line. There's also a small rub mark on the lower left side of this area, and the case sides show light marks. Please see images for full condition details.

Strap is uncut, with stickers still on the clasp.

All functions operating as they should, and remains under manufacturers warranty.

Comes with outer sleeve, outer box, inner watch roll, booklet, warranty card and spare FKM rubber strap.
