Why Siam Horolog
What Sets This Workshop Apart
Unhurried Diagnostics
Every watch is examined thoroughly before any work begins. Nothing is assumed — each timepiece tells its own story under the loupe.
Written Service Records
Timing readings, parts replaced, and observations are logged. The owner receives a clear written account alongside the completed watch.
Water Resistance Testing
Where the case design permits, each watch is pressure-tested after service. Results are included in the written service report.
Manufacturer-Grade Parts
Replacement springs, gaskets, and other components are sourced from established suppliers. No generic substitutions on critical components.
Open Communication
Any observations noted during inspection are shared clearly. Questions are welcome at any stage of the service process.
Central Bangkok Location
The workshop sits on Silom Road in Bang Rak — straightforward to reach by BTS, MRT, or private transport.

Common Questions
Frequently Asked
How long does a full service overhaul take?
A full movement overhaul typically takes ten to fourteen working days. Chronograph and complication services require a minimum of seven days of observation after assembly, so the total time is generally three to four weeks. We keep the owner informed as the work progresses.
Is same-day service available for battery replacement?
For most standard quartz models, yes — the watch can be collected on the same day. If the case design requires extra care or the inspection reveals something worth discussing, we may ask to keep the watch overnight for a thorough rest-and-recheck.
What brands and movements do you service?
We work with a wide range of Swiss and Japanese movements, including ETA, Seiko, Miyota, and Sellita-based calibres. Some highly specialised complications may require a discussion before we confirm the scope of work. Please bring or send the watch and we will assess it before committing.
Do you provide a written record after the service?
Yes. For overhaul and complication services, we produce a written report that includes timing readings before and after the work, a list of parts replaced, and any observations made during the inspection. This document is handed to the owner along with the watch.
How should I send my watch for service?
The preferred approach is a direct drop-off at the workshop on Silom Road, where we can examine the watch together. If you are outside Bangkok, please contact us first to discuss secure shipping arrangements. We do not accept watches sent without prior correspondence.
Are the prices listed final, or may they change?
The prices shown are our standard rates for each service tier. In some cases, worn or damaged parts may add to the cost — we will always discuss any additional work and receive approval before proceeding. Nothing is done without the owner's knowledge.
