AliExpress Watch Mod Compatibility Engine

Stop guessing
if it fits.

ChronosBuild checks lug width, date wheels, hand length, and case fit before you buy — then hands you the exact AliExpress parts list. Built by a modder, for the NH35/NH36 crowd.

No spam. One email when we launch — probably on r/SeikoMods first.

What it actually does

A part picker, not a parts store.

You already know AliExpress has the parts. What you don't know is whether they'll actually go together. That's the whole problem ChronosBuild solves.

01

Visual stacking

See your movement, dial, hands, case, and strap layered together before you spend a cent.

02

Mechanical constraints

Lug width, date wheel alignment, and hand length are checked automatically — incompatible parts get locked.

03

Adapter resolver

Mismatched movement in a case? We'll surface the exact spacer or adapter that makes it work.

04

Wrist-scale preview

Enter your wrist size and see the case scaled to how it'll actually sit, lug-to-lug.

05

Lume mode

Flip the lights out and preview how your exact build glows before you commit.

06

Shareable build sheet

Export your parts list as clean Markdown to post on Reddit or Discord and get feedback.
