Why This Workshop

Some things are worth
taking seriously.

Not every watch repair shop works in the same way. Here is what distinguishes the way we approach the work — and why it matters for pieces that have history or value.

Key Advantages

What working with us means in practice

Specialist knowledge, honestly applied

We work with a wider range of calibers than most general workshops, including marine chronometers and obscure vintage movements. When a piece is outside our competence, we say so.

Nothing without your agreement

Irreversible steps — refinishing, component replacement, case work — require your explicit sign-off before we proceed. The piece is yours; the decisions are yours.

Written estimates and condition records

Every piece comes in with a written condition assessment. Costs are agreed before the work begins. If something changes, we contact you before the scope expands.

Conservative treatment as the default

We do not polish, refinish, or replace what can be preserved. Original parts and original surfaces have value — especially on pieces with age and use behind them.

Realistic timelines, kept to

We give honest turnaround estimates and we meet them. If something takes longer for a good reason, you hear from us before the original date passes — not after.

Photographic documentation provided

Restoration and chronometer work is photographed at each stage. You receive the full photographic record alongside the returned piece.

In More Detail

A closer look at the way we work

Expertise across unusual calibers

Most watch repair shops focus on common movements — the Swiss and Japanese calibers that are still in production and well-supported by parts suppliers. We work beyond that range. Marine chronometer movements, vintage English lever escapements, and mid-century Thai-market imports all present different challenges. We have encountered most of them.

When a part is no longer available through any supplier, we fabricate it at the bench. This is time-consuming and reflected in the pricing for specialist work, but it is what the piece requires — and what makes the difference between a watch that runs well and one that runs for a while before failing again.

What this covers

  • Wristwatch movements from the 1920s to the 1990s
  • Marine chronometer calibers, including box and gimballed types
  • Large vintage pocket watches and deck watches
  • Small parts fabrication where originals are unavailable
  • Escapement adjustment and regulation across movement sizes

How the intake works

  • Written condition record made on arrival
  • Estimate provided and agreed before work starts
  • Owner contacted before any irreversible step
  • Photographic record kept throughout
  • Completed piece returned with documentation

A clear process from intake to collection

The process at Ayutthaya Chronos is documented at each stage. When you bring a piece in, we record its condition in writing — noting the state of the dial, hands, case, crystal, crown, and movement if accessible. This record is the basis for the estimate we provide before any work begins.

Work proceeds against that agreed estimate. If we uncover something that changes what is needed — a worn wheel, a cracked jewel, a damaged mainspring — we stop, document it, and contact you. Nothing changes without your knowledge.

Communication that doesn't require chasing

We are aware that leaving a valued piece with a workshop involves trust. Our approach to communication reflects that. You receive an update when the piece arrives, when the estimate is ready, when any significant finding emerges during the work, and when the piece is ready for collection.

If you have a question at any point, you can reach us directly by phone or email. You will speak to the person actually working on your piece — not a separate customer service function.

"We find that most of the anxiety around sending a piece for repair comes from not knowing what is happening. We try to make that a non-issue."

What Sets Us Apart

Things you won't find in most workshops

Parts made on-site when none are available

For marine chronometers and obscure vintage calibers, sourcing original parts is often impossible. We fabricate what is needed — small wheels, click springs, cannon pinions — at the bench, rather than abandoning the piece or fitting non-original substitutes carelessly.

Marine chronometer servicing in Thailand

This is a rare speciality in Southeast Asia. If you have a chronometer in working or non-working condition, or inherited one and want to understand what it is and what it would take to bring it back to timekeeping, we are one of few workshops in the region that can properly assess and service one.

A record that stays with the piece

The written condition report and photographic documentation we provide become part of the piece's history. For inherited watches in particular, having a detailed record of the work done — what was found, what was done, and by whom — adds to the piece's story in a meaningful way.

Work accepted from outside Thailand

We regularly work with owners who send pieces from elsewhere in Asia and from Europe. If you have a watch or chronometer that needs specialist work and cannot find the right workshop at home, contact us before shipping — we will advise on whether the work is within our scope and how best to send the piece safely.
