Our Take

It’s back! And it’s bigger (the power reserve that is) and badder! Following the successful release of the U50 Diver Tourbillon in 2018, Angelus introduced the U51 Diver Tourbillon 5 Day Reserve at BaselWorld 2019. The U51 gets a few upgrades including a new color scheme, a tourbillon set on ball bearings instead of pivots, and now boasts a 5-day power reserve while maintaining the 28,800 vph (4hz) frequency.

Does anyone need a tourbillon in a diver watch? Probably not. Does anyone need a luxury mechanical watch in general? You get where I’m getting at here!

This is an absolute “because why the Fu&* not” watch. And Angelus made sure the design and technical elements are executed to perfection. The new exterior bezel features a CNC milled titanium bezel inspired by ocean waves. The legibility is fantastic with the combination of blue and orange colored rotating inner bezel. The comfort level on the wrist is also fantastic with the lightness of the titanium grade 5 case, as well as the skeletonized titanium bridges and main spring.

You won’t wear a better-looking and more comfortable tourbillon to the beach, on the boat, or just your backyard pool. And should the impromptu diving session come up, you’ll have the U51 strapped on and read to go.
