What We Offer

Three Approaches to Watch Care

Each package is sized to what the watch actually needs — nothing added to inflate a bill, nothing skipped to cut corners.

Why Mainspring

What Makes the Difference

Written Record on Every Job

You receive a plain-language summary of what was found, what was done, and what parts were used. No guesswork about what happened to your watch.

One Watchmaker Per Watch

Your piece is assigned to a single technician from intake to completion. Continuity matters, especially for complicated or vintage movements.

Clear Communication Throughout

Before any significant work proceeds, we check in. You always know what is being considered and why, with no surprises added to the final cost.

Honest Assessment First

We look at the watch and tell you what it actually needs. If a lower-tier service is sufficient, that is what we recommend — not the more expensive option.

Secure Handling

Watches are logged on arrival with photographs, stored securely throughout, and returned only to the owner with a signed acknowledgement.

Walk-In Friendly, Bangkok Based

Located in Ratchathewi, easy to reach by BTS. Drop in for a quick consultation or call ahead to arrange a time that works for you.

Have a Watch That Needs Looking At?

Bring it in or get in touch. We take a look, give you a straightforward assessment, and work through the options with you — no pressure, no jargon.

Common Questions

Frequently Asked Questions

How do I know which service my watch needs?
Bring the watch in or send a brief description and we will advise you. If in doubt, the Everyday Service Package covers the most common needs for a watch that is simply due for maintenance. For older pieces we usually recommend the Vintage Refresh. The Collector's Restoration is for watches with sentimental or collector value where thoroughness and documentation matter.
How long does a service typically take?
The Everyday Service Package usually takes 7–10 working days. Vintage Refresh runs 2–4 weeks depending on part availability. The Collector's Restoration can take 4–8 weeks, as each stage is documented and approved before proceeding. We keep you updated throughout.
Are the prices listed the final price?
The prices cover the standard scope of each package. If the assessment reveals additional work — a cracked crystal, a worn crown, a faulty crown tube — we will contact you before proceeding. Nothing outside the quoted scope is done without your agreement.
Do you work on all watch brands and movements?
We work on a wide range of mechanical and automatic watches, including Swiss and Japanese movements. We do not service quartz battery watches as a main offering, though we can do basic battery and seal replacements on request. For highly specialised complications, we will let you know at the assessment stage if the work is within our scope.
Is my watch insured while it is with you?
Each watch is photographed and logged on arrival and kept in a secure environment throughout the service. We take every reasonable precaution with pieces in our care. Please contact us directly if you have specific questions about our handling procedures.
Can I drop in without an appointment?
Yes, walk-ins are welcome during opening hours. If you would like to discuss a particular restoration project in more detail, calling or messaging ahead means we can give you proper time and attention rather than a rushed consultation.
