A Seiko Mod is a custom-built or customized Seiko watch that combines original Seiko components with aftermarket parts. These modifications can include changes to the dial, bezel, hands, crystal, or case — allowing you to create a unique timepiece that reflects your personal style while maintaining Seiko’s reliable movement and craftsmanship.
Seiko Mods are based on genuine Seiko watches or Seiko movements but feature custom or aftermarket parts. While they’re inspired by Seiko’s iconic designs, they are not official Seiko products and are considered custom creations by independent modders or builders.
Processing and assembly times can vary depending on customization. Typically, orders are shipped within 9-14 business days. Once your watch is dispatched, you’ll receive tracking information so you can follow your delivery’s progress.
Assembly: 2–4 business days
Shipping: 8-13 business days
Every order includes a free bracelet adjustment kit, so you can easily resize your watch at home. The kit allows you to remove or add links for the perfect fit.
