Baltic x SpaceOne Seconde Majeure introduces jumping-hour display by Théo Auffret

Baltic and SpaceOne unveil the Seconde Majeure. A collaboration featuring a jumping-hour module by Théo Auffret and Soprod P024. Price: from €2,500.

Baltic and SpaceOne have joined forces to create the Seconde Majeure, a timepiece focusing on an original jumping-hour display developed by independent watchmaker Théo Auffret. 

Rather than combining familiar elements from the two brands, this first collaboration introduces a distinct design language built around an unconventional way of reading time.

Housed in a 38.5 mm case, the Seconde Majeure displays the jumping hours at 12 o’clock and the trailing minutes at 6 o’clock, both indicated by rotating sapphire discs.

A large central seconds hand sweeps above the dial, adding motion to a composition defined by symmetry and visible mechanical elements. 

The jumping-hour mechanism is integrated into the dial side and partially exposed. 

Beneath the minute disc, a control wheel completes one rotation every 60 minutes before engaging a star wheel connected to the hour disc. 

A visible jumper spring stores and releases energy, allowing the hour display to change instantaneously at the top of the hour.

The dial, cut from a single piece of maillechort (German silver), also serves as a structural component supporting the complication module. 

Two finishes are available: a brushed version and a hand-finished Charbonné execution, the latter produced directly in Théo Auffret’s atelier. 

For this collaboration, the brands have utilized 904L stainless steel, a high-alloy material that offers superior corrosion resistance and a higher, more brilliant polish compared to the industry-standard 316L.

The case measures 47.5 mm lug-to-lug and 12.3 mm thick. 

Brushed surfaces are contrasted by a polished concave bezel, while curved lugs improve comfort on the wrist. 

Power comes from the automatic Soprod P024 calibre operating at a frequency of 4 Hz (28,800 vibrations per hour) with a 42-hour power reserve, fitted here with the exclusive jumping-hour module.

The watch is paired with a beige Alcantara strap by Delugs. Water resistance is rated to 50 metres.

The Seconde Majeure will be available for pre-order from 12 to 17 May 2026, with production limited to the number of orders placed during that period. 

Prices before taxes are set at €2,500 for the Brushed version and €3,500 for the Charbonné model. baltic-watches.com
