The Freak 2303-270/BLACK, seen from the bench

The Freak was introduced by Ulysse Nardin in 2001 as a watch without a traditional dial, where the movement itself serves as the time indicator. It is equipped with the UN-230 caliber with a time display system through the rotation of the central mechanism. The reference 2303-270/BLACK features a case with a black treatment and a crown positioned on the caseback for adjustment.

Frequently asked questions

Can a standard strap be mounted on the Ulysse Nardin Freak 2303-270/BLACK?

No, the Freak's attachment point does not correspond to standard dimensions. However, a bespoke strap is the perfect solution: <a href="/pages/casati-booking">Casati Milano</a> measures your watch directly and crafts a strap that integrates organically with the case, respecting the model's proprietary geometry.

How does the bespoke strap creation process work for this model?

During your appointment at our Milan atelier, the craftsman examines your Freak 2303-270/BLACK, takes precise measurements of the attachment point's width and thickness, and discusses leather selection with you. The strap is then hand-crafted to match your case's geometry exactly, without compromise.

Which type of leather suits the character of the Freak 2303-270/BLACK?

A leather with marked grain or natural texture aligns with the model's radical philosophy. A dark pull-up that develops patina with use amplifies the conscious materiality of the titanium and black ceramic, avoiding any decoration that would contradict the Freak's visual language.

How long does an artisanal strap crafted by Casati Milano last?

A strap built with quality leather and sartorial technique lasts for years, with continuous visual evolution thanks to natural patina. Longevity depends on use and care, but a fine leather subjected to artisanal craftsmanship represents an investment that exceeds the useful life of many industrial accessories.

Why is the Ulysse Nardin Freak 2303-270/BLACK so different from other luxury watches?

The Freak abolishes traditional horological codes: no printed dial, no classical hands, no side crown. The movement itself becomes visual architecture. The combination of titanium and black ceramic, together with the proprietary UN-230 calibre, transforms the watch into a manifesto of pure engineering, demanding conscious aesthetic awareness from its owner.
