The CHPTR_Δ [MdP], now in 40 mm. The blue configuration that became a favourite in 44 mm returns in a more compact format. Its sculptural dial brings together a conventional minute hand and a yellow hour marker that traces a triangular path. Designed and assembled in Neuchâtel.

TIME TAKES A DIFFERENT PATH

The minutes move in a circle. The hours follow a different course: a yellow point traces a softly curved triangle across the dial. An invitation to watch time unfold, rather than simply read it.

WATCHMAKING EXPERTISE

FROM LA CHAUX-DE-FONDS TO NEUCHÂTEL

The CHPTR_Δ reflects the watchmaking expertise BA111OD is building within its own ecosystem. Its distinctive hour display was developed with watchmaker Olivier Mory at BCP Tourbillons in La Chaux-de-Fonds. 

Following BA111OD’s acquisition of BCP in 2026, that movement development expertise became part of LAB 11:10: a space for exploring new ideas in mechanical watchmaking and turning them into complications with a character of their own.

 The CHPTR_Δ [MdP] 40 mm brings this work to the wrist. Designed and assembled by BA111OD in Neuchâtel, it connects the movement expertise of La Chaux-de-Fonds with the design and hands-on watchmaking of the brand’s home city.

Swiss mechanics, revealed

At the heart of the CHPTR_Δ [MdP] 40 mm is a Soprod M100 automatic base movement, paired with the BA111OD 09310 module developed with watchmaker Olivier Mory at BCP Tourbillons. The transparent caseback reveals the automatic movement beneath.
