Automatic - 40mm - Clear caseback

Build your own Datejust-style custom watch with the MedoMods Seiko Mod Configurator. Choose your dial, bezel, case finish and bracelet to design a clean, dressy everyday piece — powered by the genuine Seiko NH35 automatic movement.

Discover the MedoMods Seiko Datejust Style Collection – custom built Seiko mods that bring together classic Datejust-inspired design and the reliability of the Seiko NH35 automatic movement.

Every watch in this collection is hand-assembled to order. We use high-quality third-party aftermarket (non-OEM) parts, sapphire crystal and 904L stainless steel cases and bracelets to create a sharp, daily-wear ready Seiko mod.

Choose your perfect Datejust-style Seiko mod:

• Dials: Arabic dial, Roman dial, diamond dial, sunburst, Wimbledon, Green Leaf, White Texture and more

• Sizes: 36 mm, 39 mm and 41 mm case options

• Bracelets: Jubilee, Presidential or Oyster style stainless steel bracelets

• Finishes: Steel, rose gold, two-tone and black or coloured dials

All watches are powered by the Seiko TMI NH35 movement (hacking & hand-winding), regulated and checked before shipping. Each piece is built as a unique custom Seiko mod watch, not a mass-produced factory model.

This collection features Seiko mod watches using OEM Seiko movements and third-party aftermarket parts.

If you are looking for a Seiko Datejust style mod, Seiko NH35 mod or a custom Arabic or Roman dial build, this collection is the best place to start.
