At Watch Mod, we specialize in designing and assembling high-quality custom watches powered by automatic movements from Time Module Inc. (TMI) — a subsidiary of Seiko Instruments Inc. (SII). These include renowned calibers such as the NH34, NH35, NH36, NH38, NH70, and NH72, as well as hybrid meca-quartz movements like the VK63, VK64, and VK61. Every timepiece is hand-assembled with care, combining modern customization with the craftsmanship of traditional watchmaking.

Watch Mod is not affiliated with Seiko or any other watch brand.
All components including TMI movements are sourced from independent aftermarket suppliers. Our watches are built using parts that are not manufactured, approved, or endorsed by Seiko or any official brand. Any references to brand names are used purely for descriptive and compatibility purposes.

You are purchasing a fully customized timepiece.
Our watches may feature modifications to the case, dial, bezel, hands, or other mechanical and aesthetic components. Dials and parts may be custom-made or sourced from the secondary market. These modifications are common within the watch modding community, but please note that Seiko or other original manufacturers may refuse servicing or repairs on customized models.

We guarantee that each watch is equipped with an authentic movement sourced from a reputable supplier. However, we cannot be held liable for any third-party service policies or delivery-related delays.
