Why Rattana Time

What sets the work apart

Transparent Assessment

Before anything is done, we explain what the watch needs and why. No surprises on the final receipt.

Respect for Original Finish

We advise honestly when polishing would do more harm than good — a watched-over character often matters more than a mirror shine.

Realistic Timelines

Same-day for battery work, a day or two for case tidying, two to three weeks for a full overhaul. We keep you updated throughout.

Proper Water Resistance Checks

Every battery service includes a pressure check — not just a new cell dropped in and the case sealed back up.

Timing Report on Overhauls

Mechanical overhauls conclude with a printed timing report so you can see the regulation result for yourself.

Easy to Find in Chiang Mai

Located on Chang Khlan Road, close to the Night Bazaar area — convenient whether you are a resident or visiting the city.

Questions

Common questions

How long does a battery change take?

Most battery and seal refreshes are completed the same day. If you come in the morning, your watch is usually ready by the afternoon. We'll let you know at drop-off if there is anything unusual that might take longer.

Do you work on all watch brands?

We work on most quartz and automatic watches — dress watches, daily wearers, and older automatics. We'll tell you honestly if a particular movement is outside what we handle well, rather than taking it on and not doing it justice.

What does a mechanical overhaul include?

Full disassembly, ultrasonic cleaning, fresh lubrication, and careful regulation. The work concludes with a timing report so you can see the before-and-after performance. Seal condition is also checked as part of the process.

Will polishing remove the original brushed finish?

It can. Brushed and satin surfaces require different techniques than polished ones, and over-polishing erases sharp case lines. We discuss this with you before starting, and sometimes the right advice is to leave the finish as it is.

What are your prices?

Battery & Seal Refresh starts at ฿1,430. Light Polish & Tidy starts at ฿2,560. A Mechanical Overhaul starts at ฿4,140. If we discover additional needs during the work, we'll contact you before proceeding.

Can I leave my watch while visiting Chiang Mai?

Of course. Battery services are same-day, so that works well even for shorter visits. For overhauls, we can communicate by email while you travel and arrange collection or shipping when the watch is ready.
