At ETRNO Custom Watches, we specialize in creating and selling high-quality custom watches that utilize 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 parts assembled by hand.

We are not affiliated with any of the brands shown; all these are aftermarket parts, such as Seiko TMI NH movements, and are handcrafted with various non-OEM or OEM suppliers’ parts to create unique custom-modified pieces. “Custom” and “Made to Order” in the listing mean that the piece(s) is/are made to order and is not from the Seiko factory nor 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 can include modifications to the case, hands, or bezel of the watch, or artwork and designs on the watch dial. In the case of watch dials, they may be custom original dials or dials manufactured in the secondary market. These modifications are common within the luxury watch industry, particularly with Seiko watches. It should be noted that under certain circumstances, Seiko may reject the servicing or repair of modified watches without their express authorization. We guarantee that this watch has a genuine TMI movement. We are not responsible for any delays.
