Sampling converts a supplier's promises into an object you can test. Stock samples ship fast, customized samples take longer (our anchor: about 20 days), and there is a specific 7-point checklist that catches the failures budget smartwatches are known for. Here is the full process.
A sample is the cheapest insurance in sourcing: it converts a supplier's promises into an object you can test. Reputable manufacturers expect to send samples before bulk orders, and how they handle the sample stage predicts how they will handle production. Skip it only when you have already validated the exact model from the same factory in a previous order.
Sample cost depends on the model and the customization level — a stock unit costs less than a custom-finished unit with your firmware and packaging. Timeline follows the same logic: stock samples ship quickly, customized samples take longer because they run through the same steps as production at small scale. As a practical anchor, our sample orders take about 20 days including customization confirmation. Always confirm both cost and timing in writing before you pay.
1. Battery under real use — not the spec sheet number, but days of actual wear with notifications on. 2. App pairing and stability — pair the watch to your own phone and use it for a week. 3. Screen and touch response in daylight and indoors. 4. Strap durability — the first thing users break. 5. Charging — does the cable seat firmly, does it charge reliably overnight. 6. Packaging — does it survive a drop test, because it will ship at least once. 7. Materials and finish — match them against the photos you will use in listings.
When the sample passes, the next step is a trial order — a first production run at or near MOQ to validate consistency between the sample and the batch. Inspect the trial batch against your golden sample before approving shipment. This two-stage approach (sample, then trial) is standard practice and any supplier who resists either stage is telling you something.
Samples are produced in our own Dongguan factory and take about 20 days including customization confirmation; cost depends on model and customization level. Tell us which category you are evaluating and we will confirm sample terms in writing before you pay anything.

It depends on the model and the customization level. Expect to pay more than the unit price at volume, because setup work is amortized over one unit instead of thousands. Get the cost in writing before paying.
Test both. The watch is only half the product — pairing stability, app permissions and notifications are where budget smartwatch programs fail first. Use the sample on your own phone for at least a week.
The approved sample both parties agree production must match. Keep it sealed and compare the trial batch against it before approving shipment — it is the reference point for any later quality discussion.
