A new generation of Chapter 4 Tourbillon T.V.D.

The new generation of Chapter 4 Tourbillon T.V.D.  represents an important milestone for BA111OD and a powerful expression of the Maison’s ambition to make the exceptional accessible without ever compromising on watchmaking substance.

From the beginning, the tourbillon has held a special place in the world of fine watchmaking. It is one of those complications that carries immediate emotional weight, but also demands real technical credibility. For BA111OD, approaching the tourbillon has never been about spectacle alone. It has always been about proving that high watchmaking can be made more open, more contemporary, and more accessible while remaining serious in its execution.

This new generation of Chapter 4 Tourbillon T.V.D. gives that ambition a new level of expression. At its heart is BA111OD’s first internally developed tourbillon movement within its strengthened technical ecosystem. This hand-wound mechanical calibre beats at 3 Hz and delivers an impressive 120-hour power reserve. The watch head is also certified as a chronometer by Timelab, the Geneva Chronometric Observatory, reinforcing the precision credentials behind the piece.

These are not details added for effect. They define the watch. They show that this new generation is not simply a visual update or a new variation on an existing model. It is a more mature watchmaking proposition, built on stronger technical foundations and designed for collectors who care as much about what is inside the watch as what appears on the dial.

That does not mean emotion disappears. Quite the opposite. A tourbillon should fascinate. It should create tension between mechanical precision and visual poetry. It should make the movement feel alive on the wrist. The Chapter 4 Tourbillon T.V.D. embraces that dimension fully, while staying true to BA111OD’s own design language: bold, contemporary, distinctive, and rooted in a vision of Swiss watchmaking that feels alive rather than distant.

This balance is what makes the piece so important within the BA111OD universe.

It expresses a higher level of technical ambition, but it still feels true to the Maison’s philosophy. It is serious without becoming cold. It is aspirational without becoming detached. It speaks to collectors and enthusiasts who want genuine horological content, but also to those who believe high watchmaking should still feel vibrant, human, and emotionally engaging.

The new generation of Chapter 4 Tourbillon T.V.D. also reflects the broader momentum behind BA111OD today. As the Maison continues to strengthen its technical capabilities and deepen its watchmaking legitimacy, this watch stands as a visible expression of that progress.

It is a watch that says something clearly: BA111OD is continuing to grow, not away from its original promise, but deeper into it. Making the exceptional accessible is easy to say. It is much harder to prove.

A watch like this is how that promise becomes tangible. For collectors, enthusiasts, and everyone who has followed BA111OD’s journey with curiosity, the new generation of Chapter 4 Tourbillon T.V.D. is more than a launch. It is a statement of intent.
