At Watch and Mods , we specialize in the creation and sale of high-quality custom watches using NH35 movements from Time Module Inc. (TMI), a subsidiary of Seiko Instruments Inc. (SII). Our watches are designed with passion and a deep respect for watchmaking tradition, using selected, high-quality, hand-assembled parts.

We are not affiliated with any of the brands shown; these are all aftermarket parts, like Seiko TMI NH movements, and are handcrafted using various parts from OEM and non-OEM suppliers to create unique, custom-modified pieces. "Custom" and "Made to Order" in the description mean that the piece(s) are custom-made and do not come from a Seiko factory or are related to Seiko.

Please note that you are purchasing a customized Seiko watch. By definition, this is a Seiko watch with the addition of custom or aftermarket parts. Customizations may include modifications to the watch case, hands, or bezel, or artwork and designs on the watch face. In the case of dials, these may be custom original dials or aftermarket dials. These modifications are common within the luxury watch industry, particularly with Seiko watches. Please note that, under certain circumstances, Seiko may refuse to service or repair modified watches without its express authorization. We guarantee that this watch has a genuine TMI movement. We are not responsible for any delays.

At Watch and Mods , we don't just create watches: we design pieces that tell your story. Discover the world of Seiko Mods and wear a masterpiece made to last on your wrist.
