Lifestyle brand GARRACK, known for its frequent collaborations with Japanese anime IPs, has previously teamed up with hits like "Jujutsu Kaisen" and "Attack on Titan," even dropping a reverse-blade katana kitchen knife from "Rurouni Kenshin"! Their fun crossover merch always gets rave reviews.
Now, they're partnering with the highly anticipated "Chainsaw Man – Reze Arc" film to release a series of smartwatches featuring four iconic characters. Priced at 9,900 JPY, these are available for pre-order now on GARRACK's official website.
The four styles are themed after Denji, Reze, Makima, and Aki. Each watch boasts a complete character makeover, from the strap to the exclusive screen interface design.
Each watch boasts unique heartbeat-triggered animations – hit a certain heart rate, and your character transforms! Get a notification, and adorable Pochita pops up. Plus, there are character-specific battery level animations. And it's not just pretty faces! These watches pack a punch with fast charging, up to 14 days of battery life, stress detection, and sports management. Weighing in at a featherlight 14g (without the strap), you'll barely know it's there!
▼ Denji Model
Hit a certain heart rate, and watch the chainsaw pull cord on the screen get yanked, transforming Denji into Chainsaw Man! The battery display is a chainsaw, shrinking as power drains. The strap itself features Denji's iconic chest pull cord and chainsaw design – instantly recognizable!
▼ Reze Model
When your heart rate hits a certain point, Reze's collar pin is pulled, transforming her into the Bomb Devil (Bombe)! Low battery? The bomb's fuse gets shorter, giving off a real "about to explode!" vibe. The strap design features Reze's signature flowers in a unique purple hue.
▼ Makima Model
Reach a certain heart rate, and Makima on screen gradually reveals her full-color design. As the battery dwindles, the steam from her coffee cup fades, perfectly capturing her calm, unhurried aura. The strap features Makima's distinctive eye pattern – fans will spot it a mile away!
▼ Aki Hayakawa Model
Hit a certain heart rate, and Aki on screen slowly reveals his full-color design. Low on power? His cigarette gets shorter, a subtle nod to one of his key symbols. The strap features a smoky line pattern, simple yet full of character.
Functionality is top-notch too: enjoy fast charging and long-lasting battery life – a 5-minute charge gives you about 2 days, and a full charge lasts up to 14 days! It also includes stress management, assessing your stress levels via Heart Rate Variability (HRV).
Plus, it supports 100 sports modes to match your workout style, along with features like alarms, blood oxygen detection, music control, timers, breathing exercises, phone finder, notifications, weather, sleep tracking, and more.
Each watch comes in its own specially designed box and includes quick-release custom straps for effortless swapping.
