Chainsaw Man’s first movie arc is jumping from the big screen straight onto your wrist. GARRACK, a Japanese lifestyle brand known for high-end character collaborations, is launching four smart watches inspired by Chainsaw Man – The Movie: Reze Arc: one each for Denji, Reze, Makima, and Aki. Pre-orders open November 25, with general sales starting November 28. Packed with playful watch-face gimmicks, long battery life, and health tracking, these pieces are made to work as everyday gear—not just display-only merch.
GARRACK Chainsaw Man Reze Arc Smart Watch Lineup
The collection features four models themed around Denji, Reze, Makima, and Aki. Each watch is a lightweight smart wearable with character-specific art, custom faces, and exclusive packaging. All four are priced at 9,900 yen (tax included), with reservations beginning November 25 and regular sales on November 28. A dedicated feature page on WORLD WIDE WATCH showcases the lineup and details.
Character-Focused Designs for Denji, Reze, Makima, and Aki
Denji’s model echoes his chainsaw form, with an orange-and-black belt inspired by his chainsaw and chest pull cord. Reze’s watch uses floral motifs and her distinctive choker. Makima’s design leans on her hypnotic eyes, turning their pattern into a repeating strap motif. Aki’s model pulls in his cool, muted palette and cigarette imagery, landing as the most understated of the four while still clearly nodding to his character.
Playful Chainsaw Man Gimmicks on Dynamic Watch Faces
Each watch face hides a few devilish tricks. When your heart rate passes a set threshold, the on-screen character transforms: Denji shifts into Chainsaw Man, Reze into her Bomb form, while Makima and Aki get visual changes to their outfits and color accents. Battery indicators also match each character—chainsaws shorten for Denji, fuses burn down for Reze, coffee steam fades for Makima, and cigarettes shrink for Aki. Notifications even summon Pochita on-screen, turning everyday alerts into tiny Chainsaw Man cameos.
Long Battery Life, Fitness Functions, and Lightweight Comfort
Under the anime styling, these are practical smart watches. Fast charging gives about two days of use from a five-minute charge, and a full charge can last up to roughly 14 days. At just 14 grams without the strap, the body is light enough for sleep tracking and workouts. The watch supports stress monitoring via heart rate variability, walking and workout tracking with around 100 exercise modes, plus tools like timers, alarms, music control, blood oxygen checks, and sleep measurement.
Special Boxes, Custom Straps, and Everyday Styling Ideas
Each model ships in a special box featuring its character, making the watches gift-ready right out of the package. A quick-release custom strap is also included, so you can swap bands with just a button press. The slim, unisex case design and soft strap material aim to keep the look wearable for both casual office outfits and streetwear. It’s an easy way to carry Denji, Reze, Makima, or Aki into your daily routine without screaming “merch” at first glance.
Reservation Details and Online Spots for Overseas Chainsaw Man Fans
Pre-orders for all four models start November 25, with general sales rolling out on November 28 via GARRACK’s section of the WORLD WIDE WATCH site and other official channels. For the latest info, check the dedicated feature page: Chainsaw Man Reze Arc smart watch feature page.
