The purple enamel Freak S is ridiculous in a way I enjoy
91/120 bezel clicks. A sourced first look.

The purple enamel makes this Freak S look like something I would keep picking up just to watch it run. I don't normally need this much exposed mechanism on a dial, but the two angled oscillators give it a shape that I find interesting. The purple beneath them also keeps the whole thing from becoming an uninterrupted mass of grey parts. This gets 91 out of 120 bezel clicks.
Ulysse Nardin calls it the Freak S Purple Enamel, reference 2513-500LE-7AE-PURP/0A, and production is limited to 50 pieces. Current introduction coverage appeared on November 12, 2026. The official product page confirms the configuration but isn't dated. I haven't handled one, so my enthusiasm is about the published design and mechanism.
Purple below all that machinery
The enamel hour disc is the detail that makes me prefer this execution. A flat, ordinary-looking background could disappear under the movement. Here, the color is strong enough to remain visible, and it works with the violet calf-leather strap without making the watch look as though someone simply selected a bright strap at the end.
The Freak's way of showing time takes some getting used to if you're expecting two normal hands. I like that the mechanism is something you have to look at and understand. I would also want to find out how quickly I could read it on an ordinary day, because enjoying a photograph of a watch and enjoying its display every morning are different experiences.
At 45 mm, it is a substantial piece. The open architecture suits that scale better than a crowded set of conventional counters might, but I wouldn't assume the titanium makes it feel small. Its case shape and the way the strap leaves the lugs would need a proper wrist check.
Two oscillators and a differential
The automatic UN-251 has a stated 72-hour power reserve. Its twin inclined silicon oscillators and vertical differential are a large part of what you're looking at from the front. The mechanism is described as a flying carousel, so I wouldn't casually relabel the whole assembly a conventional tourbillon.
Ulysse Nardin also shows the enamel disc during assembly. Those images help explain how much of the purple surface sits underneath the moving structure. They are manufacturer material, not evidence that I've visited the workshop or tested the movement.
A verified US-dollar price and US allocation weren't available in this November 13 check. I would want both, along with a chance to try the actual case, before considering anything beyond admiration. Of the versions shown here, the purple background is the reason I'd keep coming back to this one.
