Why Mainspring

The Difference a Steady Bench Makes

A watch workshop is judged by the detail it notices, not just the work it completes.

No Shortcuts in Diagnostics

Each piece is examined before any work begins, so the scope is understood and communicated clearly.

Written Records for Every Job

Timing readings and service notes travel with the watch, giving owners a clear reference for years ahead.

Honest Communication

We explain what needs doing and why, and flag anything unexpected before proceeding.

Proper Workshop Equipment

Timing machines, pressure test equipment, and ultrasonic cleaning maintained and used correctly.

Responsible Parts Handling

Original parts are preserved wherever possible; replacements are sourced with care and noted in the job record.

Unhurried Pace

Work is scheduled so each watch receives the time it actually needs, not the time left in a busy queue.

Common Questions

Things People Often Ask

How long does a water resistance reseal typically take?

Most water resistance services are completed within three to five working days. If additional case work is needed, we'll let you know before proceeding. A short written report is ready for collection with the watch.

What does the timing sheet from the regulation service show?

The sheet records the rate measured across multiple positions before regulation and then again after. This gives you a clear before-and-after comparison and a useful baseline for future servicing.

Do I need to bring my watch in, or can I post it?

Walk-ins are welcome at our Chatuchak workshop, Tuesday through Saturday. If you'd prefer to ship, we can advise on a safe packing approach. Contact us first so we can prepare to receive the piece.

How much does the complication service cost for my specific watch?

The listed price of ฿33,500 covers most standard complication services. Particularly complex or rare movements may require an adjusted figure, which we'll discuss and confirm with you before the bench begins any work.

My watch is still running — does it still need servicing?

Running and well-serviced are different conditions. Lubricants in mechanical movements dry out over time regardless of whether the watch keeps time. A regulation check or reseal can be worthwhile even when nothing seems obviously wrong.

Will you use original parts, or substitutes?

Original components are preserved wherever possible. When a gasket or part requires replacement, we source carefully and note it in the service record. Any substitution is discussed with you beforehand.
