A Seiko mod is a customized Seiko watch built by replacing or upgrading parts like the dial, hands, bezel, case, or crystal.

These mods allow enthusiasts to create a unique timepiece that reflects their personal style—while maintaining the reliable movement and build quality Seiko is known for.

Our “Build Your Watch” section features an easy-to-use configurator that lets you design your own timepiece, component by component. From the case to the dial, every choice is yours—so your watch truly reflects your style.

Our watches are water-resistant to a certain depth, suitable for everyday activities like handwashing or light splashes.

Since each watch is custom-built, we recommend avoiding prolonged water exposure or full submersion. It's also crucial to ensure the crown is fully screwed down to maintain water resistance and protect the internal components.
