Six reasons people return to us.
No-pressure communication
We explain what we found and what it means. The decision always stays with the owner. We do not chase, upsell, or rush.
Transparent pricing in baht
Prices for each service are stated clearly. Nothing is added after the work begins without your agreement. What we quote is what you pay.
Careful, attentive handling
Cases, crystals, and dials are treated with the same care throughout the process. Protective covers are standard, not optional.
Honest turnaround times
We quote timelines we can keep. Battery services same day, mechanical services in two to three weeks. No vague promises.
Written service record
Every job comes with a brief written note of what was done. Useful for your own records and for any future service at another workshop.
Seal check as standard
Bangkok's humidity makes moisture a genuine concern. We check seals on every service — included in the price, not added as an extra.
Expertise
Fourteen years of working on movements, not just replacing batteries.
Nattawut, the workshop's lead watchmaker, has been working with both quartz and mechanical movements since 2010. That length of time matters — not because it is a number to impress with, but because certain things in this trade only become clear after handling hundreds of different movements. Unusual wear, manufacturing quirks, and age-related changes in particular calibres are things you learn to recognise gradually, not from a course.
- Quartz and automatic movements both handled
- Older and vintage movements welcome
- Honest about the limits of what we can do
What this means for you
When something unusual comes up during a service, it is more likely to be recognised and handled appropriately rather than missed. The workshop does not expand into areas it is not confident in — which keeps the quality consistent for the work it does take on.
What this means for you
You will not be left wondering what is happening to your watch. For longer services, we get in touch mid-way with an update. For quicker jobs, you will know at drop-off approximately when it will be ready. Questions are welcome at any point.
Communication
We tell you what is happening, and we do not rush you for a decision.
Watchwork takes time. The customer's side of the experience should not involve anxiety or confusion. At Chang Watchworks, we are straightforward about what we find, clear about what the options are, and patient about giving owners the space to decide. There is no script that tries to close quickly.
- Updates on longer mechanical services
- Clear explanation of findings
- No work started without agreement
Value
Priced for the work, not for a brand name on the wall.
Chang Watchworks prices reflect the time and materials involved in the actual service. A battery change with a seal check and movement inspection is ฿1,460. A complete mechanical service is ฿4,120. These numbers are posted openly because there is no reason to make pricing mysterious. The service either fits your budget or it does not, and knowing in advance means you can make a straightforward decision.
- Published pricing, no estimates that grow
- All additions agreed before work proceeds
- Advised when work is not cost-effective
What this means for you
No invoice surprises. If we find something during a service that would cost more to address, we contact you before touching it. Occasionally we advise that the service cost is not worth it relative to the watch's value — because an honest answer is more useful than a repair bill that does not make sense.
How we differ

| Progress updates | Only if you ask | Proactive on longer jobs |
| Timing report on mechanical service | Uncommon | Standard |
What sets us apart
Four things you will not find at every workshop.
We turn away work we are not right for
If your watch needs manufacturer-specific tooling or a complication we do not work on regularly, we say so clearly. We would rather direct you to someone better placed than take on a job we cannot do well.
Climate-aware servicing for Bangkok
Humidity is a constant here. We approach seal integrity and moisture protection as a standard part of every service — not something triggered by a visible problem. This is specific to working in Thailand's climate, and it matters.
The same people handle your watch throughout
Your watch is not handed between multiple technicians across different shifts. The same small team handles each job from assessment to collection, so nothing gets lost in handover and the responsibility stays clear.
Advice even when we cannot help
When the work is outside our scope, we try to point you toward the right kind of workshop, what to ask them, and what to expect to pay. A short, useful conversation now is more valuable than a polite refusal with no direction.
