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 to ensure quality and functionality. As these are modified/custom watches, they do not carry Seiko’s original manufacturer warranty.
We provide our own 1-Year Limited Warranty covering movement functionality and assembly defects (refer to warranty terms for full details).
Please note that while the watch is rated at 5 ATM water resistance, it is only suitable for light splashes and rain when the crown is properly secured. Water damage caused by improper use (e.g., unscrewed crown, submersion, or showering) is considered user error and is not covered under warranty.
Due to lighting, screen differences, and handcrafted assembly, slight variations in colour, finishing, or alignment may occur. All sales are final unless otherwise stated.
