Building your own watch is the cheapest way to own something nobody else has. A Seiko-style mod starts with three parts — a case, a movement and a dial — and AliExpress is where most modders buy all three. We ranked the parts by real orders and ratings, with prices in USD.

- Match the movement — The case listing must name your movement. NH35 (date), NH36 (day-date) and NH34 (GMT) all differ in stem position and dial feet.
- Insist on sapphire — Mineral glass scratches within weeks. Sapphire costs a few dollars more and is the single upgrade you will notice daily.
- Check the dial size — Cases list an internal dial diameter — usually 28.5 mm or 29 mm. Buying the wrong one is the most common first-build mistake.
- Buy the movement last — Cases and dials sell out in specific colours; the movement is generic and always available.
FAQ
What is a watch mod?
A watch mod is a watch you assemble yourself from separate parts — case, movement, dial, hands, bezel and strap — instead of buying it finished. Most builds are based on Seiko-style cases and NH-series movements.
Which movement should I use?
The Seiko NH35 is the standard starting point: automatic, hacking, hand-winding, widely available and cheap to replace. NH36 adds a day wheel, NH34 is a GMT.
Is sapphire crystal worth it on a cheap build?
Yes. It is usually the smallest price difference in the whole build and the only part you look at every single day. Mineral glass picks up scratches quickly.
How much does a full mod cost?
A complete build using parts like these typically lands between $60 and $150, depending on the case and whether you use a sapphire crystal and a ceramic bezel insert.
