While Naomi Osaka may have closed out the first weekend of the U.S. Open with a loss, the defending champion’s wrist looked good while doing it. The Citizen Ambassador was wearing a titanium Citizen Eco-Drive throughout her tournament, including in her third-round defeat of U.S. phenom Coco Gauff, where she displayed some real class in victory.

Osaka was also wearing a Citizen Eco-Drive when she won last year’s U.S. Open and this year’s Australian Open. She was wearing the same Eco-Drive model in a different colorway in last year’s U.S. Open, but the one she was wearing this year U.S. Open might be the best yet.

It’s a modern, unisex watch, measuring 40.5mm in diameter and 10.7mm thick. The case is a lightweight titanium, perfect for a world-class athlete like Osaka. And the dial, bezel, and strap are all a nice blue color — who cares if it’s the trend, it looks damn good.

It’s got some “smart” features, without looking or feeling like a full-on smart watch. The Eco-Drive gets notifications for incoming calls, emails, and messages, in addition to the more traditional alarm complication. The watch also syncs with a Citizen phone app.

The full line up includes the model Osaka wore during last year’s U.S. Open victory (BZ4006-01E), the model she wore during this year’s French Open (BZ4005-03E), and this new blue model (BZ4000-07L), which she also wore during Wimbledon this year.

All three models have a suggested MSRP of $700. The new blue model will be available online and in stores this September.
