Four smartwatches in collaboration with ONE PIECE are now available. They will be priced at 12,980 yen (tax included) and will go on sale on May 29, 2026 (Friday). In the fall of 2025, the first ONE PIECE collaboration watch was released in the Egghead Arc, with Luffy, Zoro, and Sanji models, and now four new models will be released as the Four Emperors models.
The four models are "Buggy," "Shanks," "Teach," and "Luffy.

The collaboration models are developed by Weni Trading's character brand " GARRACK." Based on the "HUAWEI Band 11" currently being sold by Huawei, the body color and belt are customized to match the image of each character. The screen of each watch is also different. If you like ONE PIECE, you'll want one of these highly finished products.

Each character is depicted on the package. The original HUAWEI Band 11's package is compact enough to be held in one hand, but the ONE PIECE Four Emperors model is larger in size to make it more collectible and to show off the characters' images.

In addition to each collaboration watch, this package actually includes a black interchangeable belt. You can change the belt according to your fashion or mood of the day, or you may want to be bold and not use the belt as part of your collection. Of course, the commercially available replacement belt for the HUAWEI Band 11 can also be used.
Buggy" model is "Rough Rough Fruits" and "Cross Guild".

The blue-colored "Buggy" model features a design that brings the worlds of the "Rumble Roses" and "Cross Guild" to the forefront, and a character watch face that specializes in music, alarms, and step counting gimmicks.

The watch face is implemented with exclusive visuals featuring baggy and other Cross Guild members. The step count function changes the pose of the buggy as the number of steps increases, and the user can enjoy an animation of the cross guild members eventually gathering on the screen.
The upper button on the lower left of the screen is the music control, which allows one-touch music playback operation in the image of the baby carriage's flamboyant character. The button below that is the alarm function, whose icon is based on the baby carriage's nose.

The belt features a split-pattern design that expresses the separation of body parts, based on the motif of the ability of the fruit of dismemberment. When a notification is received, a cross guild pirate flag icon appears on the dial. The same icon is also displayed at all times.
The "Shanks" model is in the "Haou-iro and Mihon-iro colors".

The "Shanks" model is based on the theme of the red color of "Haou-iro" and "Mimon-iro" and combines weather, breathing exercises, and a heart rate-linked gimmick.

The watch face is an exclusive design with a large depiction of Shanks, with an animation that changes pose depending on heart rate. The button at the bottom left and top of the screen is a weather forecasting function, with an icon that resembles the image of the "Haiken-iro no Haiken," which can see into the future. You can check the weather information with a single touch. The lower button is a breathing exercise, designed to enhance concentration. One-tap activation is supported.

In addition, a gimmick is provided to visually indicate the intensity of the exercise by changing the pose of Shanks when the heart rate exceeds a certain level. The belt is red based on the image of Shanks, with graphics expressing the "high energy of the King's colors" that he has been training for. When a notification is received, the pirate flag symbol of the Red-Haired Pirates appears on the dial.
The "Teach" model is equipped with the "Yami Yami" and "Gulagura no Mi" fruits.

The design motif of the "Teach" model is based on two abilities, "Yami Yami" and "Gulagura no Mi". The model is designed for internal management, with a focus on sleep, alarm, and stress functions.

The dial features a large image of Teach and a gimmick that changes its pose in response to changes in stress levels. Teach's pose changes in accordance with the stress value calculated from heart rate fluctuations, allowing the user to visually grasp his or her condition.
The shortcut button in the lower left corner of the screen is a sleep measurement button with the image of YamiYami fruit, which allows one-touch access to the sleep measurement screen. The lower button is an alarm function with a motif of "wobbly fruit" that allows you to confirm and set an alarm with a single tap.

When a notification arrives, the pirate flag symbol of Blackbeard's pirates appears, linking the characterization with the notification function. The belt is also based on the "Yami Yami no Mi" and "Gura Gura no Mi" fruits, and the pattern mixing the abilities of the two devil fruits is designed to emphasize Blackbeard's unique abilities.
The "Luffy" model is "Gear 5 Luffy's robe of feathers".

The Luffy model, which emphasizes workout + breathing exercises and heart rate-linked functions, is based on the Gear 5 Luffy's robe of feathers.

The dial features a large image of Luffy in Gear 5, with an animation gimmick that changes his pose in response to heart rate, representing "Luffy in battle mode. A shortcut in the lower left corner of the screen allows one-touch activation of the training mode, with the workout mode at the top. The icon features the silhouette of an active Luffy. Below is a breathing exercise that calls up a breathing workout designed to resemble Gear 5 Luffy's plumage.

When the heart rate exceeds a certain level, Luffy's pose changes to indicate the intensity of the exercise. The belt is designed in a purple motif based on the plumage of "Gear 5" Luffy, and features a dynamic line pattern.
When receiving notifications, the pirate flag of the Straw Hat crew is displayed, seamlessly connecting daily notifications with the world of the work.
