Create Your Custom Mod

Create Your Custom Seiko Mod

Build a watch that’s truly yours—case, dial, bezel, crystal, hands, strap and more.
Base custom build is the same price as the equivalent Crownlab model.
Custom dial/logo printing and special requests are extra and quoted before we start.

How it works

1) Choose base & size
Pick your style (diver, dress, field) and case size that fits your wrist.

2) Select the movement
NH35 / NH38 / NH34 (GMT) / NH05. We’ll guide you on function and accuracy.

3) Dial & logo
Choose color/finish. Optionally add your own logo or text (additional cost).

4) Bezel & insert
Count-up, GMT, smooth, or fluted—match finishes and colors to your build.

5) Crystal & case-back
Flat or domed sapphire. Solid steel back or exhibition case-back (visible movement).

6) Hands & lume
Pick a handset style and lume tone that suits the dial.

7) Strap/bracelet
Steel bracelet, rubber, leather or nylon—sized to your wrist.

8) Assembly & QC
We assemble, regulate, check alignment, and pressure-test where applicable.

9) Final approval & delivery
You’ll receive photos/video for sign-off. Typical lead time is 7–14 business days (complex builds may take longer).
