Ratana service solutions

Our Services

Three paths, one standard of care

Each tier is designed for a different situation. The watch's condition and your intentions for it determine where the work begins — and we'll help you think that through.

Our Methodology

How every service begins

Every watch that comes to Ratana is logged, assessed under magnification, and given a written condition report before any service begins. That report is shared with you, and work proceeds only once you've reviewed it. If the assessment reveals the watch needs something beyond the original tier, we discuss that clearly — including cost and timing — before adjusting scope.

Service 01

Service Inspection & Clean

A clear inspection followed by a light service: cleaning of accessible parts, gentle lubrication, timing adjustment, and a seal review. Everything found is noted plainly so you can decide on any further work with full understanding. A sensible first step for a watch returning to wear; about one to two weeks.

Service 02

Full Mechanical Service

A complete service for mechanical watches that have lost steady timekeeping. The movement is cleaned and re-oiled, the balance and mainspring reviewed and renewed where needed, and timing regulated across positions. Seals are renewed and the crown checked. Suited to daily-wear watches; around three weeks.

Our Standards

What applies to every service

Secure custody

Watches are logged on arrival and stored in a locked cabinet when not on the bench. We carry insurance for pieces in our care.

Timing machine verification

Every serviced movement is tested on a timing machine before the watch is closed. Results are recorded and included in your service report.

Correct lubrication

We use current-grade watch lubricants appropriate to each component. Lubricant type and date of application are recorded per service.

No unilateral decisions

If something unexpected is found during a service, we stop and contact you. Nothing is done without your understanding of what it involves.

Written service record

Every watch is returned with a written record of the work done, parts used, and timing results. This is yours to keep as part of the watch's history.

Thai and English

All client communication is handled in Thai and English. We respond to enquiries within one working day and give updates throughout longer services.

Not sure which service fits?

Describe the watch and what you've noticed. We'll suggest the right starting point and explain why — with no pressure to proceed further than makes sense.
