Kamen Rider Build: Wrist Watch - Harold's Gear DG Watch - Sento Model (REBOOT Ver.) (Limited Edition) (Reissue) [Bandai]

Japanese Original Edition, Fashion Accessory

The iconic “Watch That Liberal Arts Students Can’t Read” is back! Featured in the first episode of Kamen Rider Build and worn by Sento Kiryu, this unique wristwatch makes its grand return. Even years after the series ended, fans have continued to request its re-release, and now it’s finally here again.

The dial retains its original equation-based design, but the watch has been entirely redesigned for enhanced usability and casual wear. The original version, crafted as a bespoke item by skilled watchmakers, was a premium product that some fans found too delicate for everyday use. Feedback like “It’s too precious to wear” or “I’d love a more casual version” inspired this REBOOT EDITION, which maintains the stylish design while making it more practical for daily life.

Key updates include:

- Retained brass material, now enhanced with metallic plating for all metal components.
- Upgraded from non-waterproof to 3 ATM water resistance, suitable for everyday use.
- Extended leather strap length by approximately 2 cm for a more universal fit.
- Switched from luxury leather to a more durable leather material optimized for straps.
- Adjusted the watch case thickness for a sleeker profile.
- Added an engraved Kamen Rider Build logo on the back cover.

This updated version balances the original Harold's Gear aesthetic with modern practicality, making it an affordable and user-friendly product. For those who purchased the original, this can serve as a perfect second watch for casual occasions. For those who missed out the first time, now is the ideal opportunity to add this standout piece to your collection!
