A surprising partnership with a clear purpose
300 pieces total — 150 of each dial — and a €1,950 retail price. Baltic and SpaceOne didn’t team up for a logo swap. They made a watch with a single mechanical idea at its centre: a dead‑seconds module that turns the small seconds into a visible, ticking personality while the rest of the movement runs smoothly.
Design: subtle vintage cues meet a night‑sky dial
The case sticks to Baltic’s compact formula. It measures 38.5mm across, 12.6mm from crystal to caseback, and uses a gently domed sapphire and a slim polished bezel to keep the visual weight on the dial. Water resistance is rated at 100 metres, so this is meant to be worn, not boxed.
SpaceOne’s hand is most obvious on the dial. Two editions exist: a deep “Meteorite Blue” with a radial sunburst and luminescent specks that read like distant stars, and a matte “Nocturne Black” with laser‑etched micro‑dots. Both feature modest applied baton indices and a recessed seconds sector that makes the small seconds a sculptural focal point — a direct nod to the watch’s mechanical novelty.
Movement: dead‑seconds mechanics give the watch personality
The jumping‑seconds effect comes from a custom module built on a Swiss automatic base. Baltic calls the finished movement Calibre BM‑01. It runs at 28,800 vph and uses an enhanced mainspring to deliver approximately 56 hours of power reserve. The module produces the one‑second jumps of the seconds hand while leaving the rest of the gear train continuous.
Finishing fits the price tier: Côtes de Genève on the rotor and chamfered bridges visible through a sapphire caseback. The module is integrated so overall thickness stays restrained and the dial balance remains intact.

“We wanted to make a watch that felt like an idea rather than a logo,” a member of the joint design team said. “The dead‑seconds gives it mechanical character; the dial gives it atmosphere.”
At €1,950 the Seconde Majeure sits above Baltic’s core range but below bespoke dead‑seconds pieces from small independents. That pricing and the 300‑piece run point to a clear play: offer an accessible watch with a genuine mechanical twist and a coherent theme. If you value a small technical detail and a wearable vintage aesthetic, this is one to track through Baltic and SpaceOne channels; interest is likely to outpace supply.
