Mechanical Watchmaking
The Watch Enthusiasts Respect
A mechanical watch is the heart of a serious watch brand. It signals craftsmanship, holds its value, and earns the respect of buyers who know watches. For an independent brand, an automatic timepiece is what turns a fashion accessory into a real watch line.
SGARIT builds custom automatic and mechanical watches for independent brands — with reliable movements, precise case machining, and the kind of finishing that stands up to close inspection. Whether it is a dress automatic, a dive watch or an open-heart skeleton design, we manufacture it to your specification.
Movements
The Engine Inside Your Watch
Japanese — Miyota
Citizen’s Miyota automatic movements — dependable, widely serviced, and a trusted standard for independent brands. A reliable choice at accessible cost.
Japanese — Seiko NH
The Seiko NH series (NH35 and others) — robust automatic movements with hacking and hand-winding, popular for dive and sport watches.
Swiss — Sellita & ETA
For premium lines, Swiss Sellita and ETA movements are available on request — the choice when your brand positions at a higher tier.
All mechanical movements are regulated in multiple positions prior to assembly, for reliable accuracy. Movement sourcing can be documented for your records, and we will recommend the right movement for your target price and positioning.

Quick Answers
Mechanical Watch Questions
Which movement should I choose for my brand?
It depends on your target price and positioning. Miyota and Seiko NH movements suit accessible and mid-range lines; Swiss Sellita and ETA suit premium positioning. We will recommend the best fit for your project.
What is the MOQ for custom mechanical watches?
Bulk production starts at 300 pieces per model. Samples can be made from 2 pieces so you can approve quality first. Special movements or components may require a higher MOQ, confirmed in your quotation.
Can you make skeleton or open-heart designs?
Yes. We build open-heart and skeleton automatic watches, along with exhibition case backs that show the movement.
How long does a mechanical watch order take?
Sampling takes 15–45 days depending on tooling. Bulk production typically runs 30–60 days depending on movement and quantity.
What are the payment terms?
A deposit begins production, with the balance paid after final QC approval and before shipment — you settle the balance only once quality is confirmed.
