A Seiko mod is a custom-built watch that uses a Seiko automatic movement inside a case, dial and bracelet styled after an iconic luxury design. You get the look of a classic watch with a reliable mechanical movement, at a fraction of the price of a luxury piece. Seiko mods are not made or endorsed by the luxury brands whose designs inspire them – they are their own category of watch.
The movement
Most Seiko mods are built around Seiko’s NH-series automatic movements, which are widely used, easy to service and known for reliability. An automatic watch winds itself as you wear it, so it is worth wearing it regularly or using a winder.
Popular styles
