Sunray
太阳纹Radial brushing that moves with the light. The most classic finish — and the hardest to keep even across a full run. One dial that reads differently from its neighbour is a reject.
Movements are admired by collectors. Cases are noticed at a distance. But the dial is where every glance lands — twelve indexes, one logo, a few tenths of a millimetre of light and shadow.
We do one thing: making that surface exact. Brass, stainless steel, copper alloy. Sunray, guilloché, multi-colour printing, diamond-set, openwork, mother-of-pearl.
Our tolerance is ±0.02mm. Not because a catalogue says so, but because at 5× magnification, anything larger is visible to the person wearing it.
Every finish below is done in-house. Pick the one closest to your concept — we will tell you honestly if it is not the right process for your quantity, budget or deadline.

Radial brushing that moves with the light. The most classic finish — and the hardest to keep even across a full run. One dial that reads differently from its neighbour is a reject.

Traditional engine-turned pattern. Concentric and radial lines interlock, so the cut has to run without a break — a single hesitation shows up under any raking light.

Micro-setting with stone-level traceability. Drilled, chamfered and seated in three passes. One missing or misaligned stone means the dial is stripped and redone.

Up to six colours of pad and screen printing, registered to the dial centre — crests, maps, illustrated motifs, relief effects. Matched to Pantone or to a sample you send.

The movement shows through. Open area and structural strength have to be solved at the same time — cut too much and the dial no longer holds its shape on the movement.

Natural shell, no two alike. The light band has to be read on the raw blank before cutting, otherwise the dial ends up with its glow off-centre.
Stamping, CNC, polishing, pad printing, diamond setting, final assembly — in the same building.
That matters more than it sounds. Every time a part leaves one factory and enters another, your tolerance loses a little. Handing a half-finished dial to a subcontractor is how a ±0.02mm becomes ±0.05mm and nobody can say where.
We keep it inside. Not out of pride — out of arithmetic.
Below is the floor as it runs on a normal working day: machines on, work in progress, nobody posed for the camera.
Three checks, every single dial, no sampling. A dimensional report goes out with every shipment.
Dimension, appearance, and a 5× loupe pass for dust, burrs and scratches. The third one is the one that catches what a gauge cannot.
Every batch leaves a retained sample in the cabinet, kept two years. So a reorder in 2028 still matches the run from 2026 — not a photo of it, the actual part.
Every dial measured on critical dimensions — not a sample from the batch.
Dust, scratches and burrs. At 5× nothing hides — including what the buyer will see.
Two years per batch. Reorders are matched to the physical part, not a colour code.
Hangs on the wall. Everyone on the floor judges a reject by the same standard.
You hold a physical sample and approve it in writing. Production starts only after that, so “close enough” never scales.
Every dial can be traced back to the plating tank, the paint batch and the press die it came off. That is why a colour drift gets answered, not discussed.
Self-declaration for brass, steel and every plating process, issued with the shipment. Laboratory test reports can be commissioned at cost.
Your designs are never shown in our portfolio without written permission.
If you cannot fly here this quarter, start with this. Zhou Mingdong has been making dials since 1990 — 66 seconds, from a workshop in Shenzhen to the plant he runs today.
Design and tooling, stamping and blanking, dial feet, CD pattern and grinding, plating and coating, printing and assembly. Nothing is sent out, so nothing waits in someone else's queue.
Shot on site at the Qingyuan plant. Nothing staged — the machines were running anyway.
Five steps, and you know the status of every one of them.
We confirm tolerance, material, finish and assembly fit. Questions are raised before tooling, not after shipping. Quote back within 2 working days.
Fifteen days for a physical sample. Colour, texture and hand-feel are approved in the hand, not on a screen.
Thirty days from approved sample. Weekly photo updates on the line, so you are never guessing.
Dimension and appearance on every dial, 5× loupe re-check. Non-conforming parts never leave the building.
FOB Shenzhen or DDP door-to-door. Individual foam trays, dust-free packing, full export documentation.
We turn down work outside this range — it is cheaper for you than finding out at inspection. Inside it, the tolerance is ours to carry.

Both work. A PDF, DXF or STEP file is enough to start; a physical sample helps us match finish and feel faster. Send whichever you have — we reply with a process review and a quotation within two working days.
100 pcs per colour for production runs. Sampling and prototypes start at one piece, with no MOQ — most of our long-term customers began with a single sample order.
Your contract, invoice and shipping documents come from Qingyuan Yifang Technology Co., Ltd. (清远一方科技有限公司) at the Qingyuan address above. HENGWEI is the brand this workshop has traded under since it operated in Guangzhou as Guangzhou Hengwei Watch Parts Co., Ltd. — the same team, the same tooling, a larger plant. If your purchasing department needs the business licence and the association certificates before opening a supplier file, we send all of them with the quotation.
Yes, before drawings change hands. Your designs are never published, shown at trade fairs, or used in our portfolio without written permission. If confidentiality is the reason you have not approached a Chinese supplier yet, start with this conversation.
Tooling made for your reference is used only for your orders. No logo, dial or sample leaves the building without written approval, and retained samples are kept in a locked cabinet — which also protects your consistency on reorders.
Yes — FOB Shenzhen or DDP to your door. REACH and RoHS declarations are provided for all materials and plating processes. We currently supply brands in 14 countries; express samples usually arrive in 3–5 days.
Because every dial is inspected, we usually know before you do. Non-conforming dials are remade at our cost, and the inspection report that ships with each batch is the record both sides work from.
Send a drawing or a reference photo through the form below. You will get a process review, an indicative price and a lead time — no obligation, no sales sequence.
We reply with a process review and an indicative price — usually within 24 hours, Monday to Saturday, GMT+8.
