With a robust 40mm steel case, this watch speaks of strength and endurance. Its signature crown, positioned strategically at 4 o'clock, is a nod to both tradition and innovative thinking. However, it's the dial that truly captures the heart; carved from deep black onyx stone, it presents a luxurious vista. But the pièce de résistance is, undoubtedly, the cut-out at 7 o'clock – a window that offers a glimpse of the mesmerizing dance of the tourbillon.

The inner workings of this masterpiece are powered by a skeletonized hand-wound mechanical movement by Olivier Mory. With a staggering 105-hour power reserve, this watch doesn't just measure time – it challenges it. And for the true aficionados, the caseback unveils a world of intricate craftsmanship. An additional touch of genius, a mirror film on the back of the dial, reflects the upper face of the movement, letting the wearer delve deeper into its magic.

To wrap around your wrist, we've chosen an ethically conscious crocodile-style leather strap. The folding clasp adds to the convenience while the dual NFC chips embed modern tech into this classical beauty.

A fine Tourbillon on Onyx dial

Thanks to the dedication of Ba111od team, I recd my watch before Christmas as promised. Kudos to all the work on it!

The watch is beautiful, well thought design, good aesthetic and visual. My watch is without the word Tourbillon on its dial and that enhances the display element.

The case is well polished and the crown is comfortable to manage. The reverse sapphire back gives a sumptuous view of the movement.

A couple of small recommendations if I may. It will be ‘nicer’ if the letters of the brand is a tad smaller, so that it does not shout at you when you are looking at the watch. Also a discreet minute/ hour makers will be a valuable addition.

Overall this is an excellent example of a mid-range Tourbillon. Once again kudos to Thomas and the team for bringing us this watch.

Have a successful 2024!
