Architectural Jump Watches

The Seconde Majeure Uses Jumping Hours and a Central Seconds Hand

The Baltic x SpaceOne Seconde Majeure is a limited-edition watch created by the two French brands with a jumping-hour module developed by Théo Auffret. The watch displays hours at 12 o’clock and minutes at 6 o’clock, with both readings shown through sapphire discs and a crosshair-style pointer. A long central seconds hand gives the model its name. The case measures 38.5mm in stainless steel with a 12.3mm thickness, a concave polished bezel, brushed surfaces, and a crown positioned at 12 o’clock.

The watch uses a Soprod P024 automatic movement with a custom jumping-hour module. Two dial versions are available: brushed and charbonné, with the latter finished by hand. Pre-orders run from May 12 to 17, 2026, and production will match the number of orders placed during that window.

Jumping-hour Modularization
The integration of a discrete jumping-hour module into a standard automatic movement suggests scope for compact, swap-in timekeeping components that redefine mechanical watch architectures.
Architectural Dial Displays
Visible layered elements like sapphire discs and crosshair pointers create opportunities for rethinking legibility and spatial storytelling in miniature instrument faces.
Order-driven Limited Production
Short pre-order windows that calibrate production exactly to demand point toward flexible, low-inventory manufacturing models tied to direct consumer commitments.

Who This Affects Most

Independent Horology Suppliers
Specialist module developers and boutique movement houses can capture value by producing innovative plug-and-play complications for small brands seeking distinctive mechanics.
Advanced Materials Manufacturing
Producers of thin, high-clarity sapphire components and novel finishing techniques may enable new aesthetic and functional possibilities for premium watch surfaces.
Direct-to-consumer Luxury Retail
Brands using tightly timed pre-orders and made-to-demand runs are reshaping customer acquisition, pricing transparency, and scarcity narratives in high-end goods.
