All watches sold by Watchkraft are aftermarket custom builds using genuine movements and third-party mod components. We are not affiliated with Seiko Holdings Corporation or any other brands.
Each timepiece is carefully assembled and tested by our team to ensure quality and functionality, but as these are modified/custom watches, they do not carry Seiko’s original manufacturer warranty.
We offer our own 1-Year Limited Warranty covering movement functionality and assembly defects (see warranty terms for full details). Please note that water resistance is not guaranteed, Our watches are rated at 5 ATM water resistance, meaning they are suitable for light splashes and rain only when the crown is properly screwed down.
If the crown is left unscrewed or not secured tightly, water may enter the case, potentially damaging the movement. This is considered user error and is not covered under warranty. We strongly advise avoiding submersion, swimming, or showering with any modded watch, regardless of its rating.
Due to lighting, screen settings, and handcrafted assembly, slight variations in color, finish, or alignment may occur. All sales are considered final unless otherwise stated.
