Ueni Trading Co., Ltd. has announced that GARRACK, its character collaboration brand, will release a new series of smartwatches based on the Four Emperors from ONE PIECE. Pre-orders open on April 27, with general availability beginning May 29, 2026, priced at JPY 12,980 each.

This is the second collection in GARRACK’s ONE PIECE smartwatch lineup. Building on the success of the first release, this new series introduces four models, each inspired by one of the Four Emperors: Buggy, Shanks, Teach, and Luffy.

Every model comes with a character-themed strap, an original watch face, and interactive dial animations that respond to activity data. Each watch also includes notification effects featuring pirate crew emblems and two customizable shortcut keys. The designs are meant to bring elements of the ONE PIECE world into daily wear while still functioning as a practical everyday smartwatch.

Each model comes packaged in a special edition box and includes an interchangeable strap.

The four models and their reference numbers are:

• Buggy Model: HUC-OP-BD11-B
• Shanks Model: HUC-OP-BD11-S
• Teach Model: HUC-OP-BD11-T
• Luffy Model: HUC-OP-BD11-L

Beyond the ONE PIECE themed look, the watches are built with a range of health and fitness functions. The watch body weighs approximately 16 grams without the strap, making it lightweight for everyday use.

On the battery side, the watch supports fast charging, with just 5 minutes of charging providing up to 2 days of use. A full charge lasts up to 14 days. Health tracking features include heart rate monitoring, blood oxygen tracking, stress monitoring through HRV (heart rate variability), and sleep tracking. The watch also supports over 100 workout modes. Other built-in features include alarm, music control, a timer, weather updates, notifications, and a phone finder function.
