BA111OD is scaling down its bestselling complication, the Veblen Dilemma Tourbillon, with a new 40mm case that brings the brand’s most talked-about watch to an even wider audience. First launched as Chapter 4.1, the tourbillon has already surpassed 600 pieces sold. Now, Chapter 4.5 keeps all the hallmarks of the original while refining the proportions into a more versatile, unisex size.
The watch stays true to BA111OD’s disruptive ethos. Entirely Swiss-made and designed with Olivier Mory, it pairs a hand-wound tourbillon movement featuring a 105-hour power reserve with something no one else dared: an NFC-enabled sapphire crystal. This tiny layer of technology quietly links the mechanical beauty on your wrist to a digital concierge service, exclusive invitations, and even a personalized ownership experience. Importantly, it doesn’t interfere with the movement or aesthetics. it’s simply there when you want it, invisible when you don’t.
The 40mm case, in Grade 5 titanium with a tantalum-grey DLC finish, feels modern and wearable while retaining the sharp lines and high-end finishing that define the Veblen Dilemma. It’s a watch that sits confidently between fine watchmaking and forward-thinking connectivity, proof that BA111OD’s vision of accessible haute horlogerie isn’t just a statement, it’s a reality.
