Sony has a new version of the FES Watch, its E Ink watch that can display a variety of faces and band designs at the touch of a button. The FES Watch U adds a metal bezel to the original’s minimalist design, which may or may not to be your taste — it kind of isn’t to mine, though the product does look more refined overall.

While neither model is really a smartwatch, the FES Watch U does have a little more functionality than the original model, with extra face designs available by connecting to an app called FES Closet. Sony says it will release new designs from notable creators every month for the rest of the year. The new watch also uses a rechargeable battery that lasts up to 3 weeks; the original FES Watch used button cells that had to be replaced every couple of years.

The FES Watch U is available in Japan from today from Sony’s First Flight crowdfunding site, as well as several fashion boutiques in Tokyo. The “premium black” model costs 60,000 yen ($544), while the regular steel finish sells for 46,000 yen ($417) with a black or white strap. Both variants are considerably more expensive than the 29,700 yen original, and it’s unlikely any of them will see an official release outside Japan.
