Swiss watchmaker BA111OD has unveiled the CHPTR_Δ [MDP], a timepiece that challenges traditional Swiss watchmaking with its innovative mechanical complication and distinctive design. The watch is part of BA111OD's LAB 11:10 initiative, which aims to explore unconventional watchmaking solutions. The CHPTR_Δ [MDP] features a 40mm case made of 316L stainless steel, with a satin-matte finish and blue accents.
The CHPTR_Δ [MDP] boasts a unique triangular-shaped dial with a polished steel element and a yellow hour marker. The watch features a Super-LumiNova-coated minute hand and hour marker, allowing for easy readability in low light conditions. The dial's design is complemented by a sapphire crystal with an anti-reflective coating. The watch is available with two interchangeable bracelets: a stainless steel bracelet with a deployant buckle and a blue rubber bracelet with a double deployant buckle.
The CHPTR_Δ [MDP] is powered by an automatic Swiss movement, the BA111OD 09310, which is based on the Soprod M100 caliber. This movement features a hypo-cycloidal mechanism that displays the hours in a unique way. The hypo-cycloidal mechanism is based on a geometric concept where a point on a circle rolling inside another circle creates a distinctive path. This results in a novel display of the hours, rather than the traditional circular rotation.
The CHPTR_Δ [MDP] has a 42-hour power reserve and features 25 jewels to minimize friction on the movement's pivot points. The watch's caseback is made of transparent sapphire, allowing for a view of the movement. The watch has a 5 ATM water resistance rating, making it suitable for occasional exposure to water, but not for diving.
BA111OD's CHPTR_Δ [MDP] will be available for purchase in late October 2026, with two versions offered: one with a stainless steel bracelet priced at €3,960 and another with a blue rubber bracelet priced at €3,760. The €200 price difference between the two versions reflects the choice of bracelet.
The CHPTR_Δ [MDP] is aimed at collectors of mechanical watches who appreciate unconventional time displays. This watch's unique design and mechanical complication set it apart from traditional timepieces. BA111OD's innovative approach to watchmaking is showcased in the CHPTR_Δ [MDP].
Lydia Mahfo, a journalist for Le Nouveau Réveil, reported on the release of the CHPTR_Δ [MDP]. The watch's design and mechanics have been carefully crafted to provide a distinctive time-telling experience.
