BA111OD Chapter 7 Chronometer Jet Black - Rubber

BA111OD Chapter 7 Chronometer

A Swiss chronometer for every day. Precision confirmed by the Geneva Observatory.

The Chapter 7 Chronometer represents an important milestone for BA111OD – it is the brand's first model with official chronometer certification. Its sporty-elegant design, integrated bracelet, 100-meter water resistance, and above all, individually tested precision make it a watch that performs equally well in the office and during an active weekend.

The 316L steel case has a diameter of 40 mm, a height of 10.5 mm, and a lug-to-lug of 47 mm. The distinctive faceted bezel and the combination of satin-brushed and polished surfaces play with light, highlighting the watch's modern architecture. The crown is unconventionally placed at the four o'clock position, and the dial is protected by a sapphire crystal with a double-sided anti-reflective coating.

Precision with a certificate

Inside works a Swiss automatic caliber Soprod P024 with 25 jewels and a power reserve of 38 hours. Each movement undergoes individual testing by the Observatoire Chronométrique de Genève – TIMELAB and achieves a certified precision of −4/+6 seconds per day.

Therefore, with each watch, you will also receive its own chronometric measurement report and an individual certificate confirming the achieved precision.

The Chapter 7 is also Swiss Made, designed and assembled directly in Neuchâtel. The automatic movement can be observed through the sapphire case back, and the 100-meter water resistance allows the watch to be used safely even while swimming.

There is a choice of a sportier rubber strap with a double folding clasp or an integrated steel bracelet with tool-free micro-adjustment.

Four colors, four characters

All variants share a sunray dial with a characteristic cascading pattern, which creates depth and changes its appearance depending on the incident light. The faceted indices are coated with Super-LumiNova.

Forest Green
The rich green version is one of the most striking variants in the collection. The sunburst finish, together with the cascading structure, plays with various shades of green – from darker forest tones to more vibrant green reflections. A sporty color that still appears sufficiently elegant thanks to the steel case and bracelet.

Absolute Blue
Deep blue is probably the most classic color choice for the Chapter 7. The sunray surface highlights the dial's structure and transitions from dark blue to more striking shades depending on the light. A versatile variant that works well on both a steel bracelet and rubber.

Frost Blue
The lightest and most airy version of the collection. The icy blue shade gives the technical design of the Chapter 7 a fresher and more contemporary character, while allowing the cascading structure of the dial to stand out well. An ideal choice for those who want something less traditional than classic dark blue.

Jet Black
The cleanest and most technical variant. The black sunray dial creates an almost monochromatic look and allows the geometry of the case, the faceted indices, and the dial's structure itself to stand out more. The result is a versatile, yet distinctly modern Chapter 7.

Why choose Chapter 7 Chronometer?

Because it offers a very interesting combination of certified chronometric precision, a Swiss Made automatic movement, sapphire crystal, 100-meter water resistance, and a sophisticated sporty-elegant design.

And chronometric certification here is not just a label on the dial. Each piece is individually tested and delivered with its own report and certificate.

About the brand

BA111OD is an independent Swiss watch brand founded by Thomas Baillod in 2019. Its name is derived from Baillod's surname, which has roots in the Neuchâtel watchmaking tradition dating back to 1775. The brand was created with the ambition to offer genuine Swiss mechanical watches in a different way – with a distinctive design, a more direct relationship with customers, and an emphasis on making quality watchmaking not exclusively reserved for traditional luxury brands.

Chapter 8 embodies this philosophy perhaps better than any other BA111OD model. It is a gateway to the world of Swiss mechanical watchmaking, but it certainly doesn't feel like a "basic" watch. It offers a genuine automatic Swiss movement, sapphire crystal, thoughtful design, hand assembly in Neuchâtel, and above all, its own character.
