What sets us apart
The reasons owners bring their watches to siamchra
Not every workshop works the same way. Here is a straightforward account of how siamchra operates and what that means for the owner.

Six things that define this workshop
Written condition reports
Every service generates a written document. The condition report describes what was found; the service summary describes what was done and how the watch performed at the end of the service period.
No work without approval
The diagnostic report is issued first. Service work starts only after the owner has reviewed the findings and given separate, explicit approval. There is no assumption that bringing the watch in constitutes consent to any particular work.
Calibre-appropriate materials
Lubricants and replacement parts are chosen to match each calibre's technical specification. The workshop maintains a range of watch-grade materials rather than applying a single standard approach to every movement.
Pressure testing included
Water resistance is verified after case reassembly on full service work. The result is noted in the written summary returned with the watch. This step is included as standard, not as an optional extra.
Permanent workshop address
The workshop is at a fixed address on Si Lom Road, accessible during opening hours without appointment for drop-off and collection. Owners can visit to discuss the piece before committing to any service.
Stated pricing in Thai Baht
Service pricing is stated clearly in Thai Baht before work begins. The diagnostic report is a defined service at a defined price, not an unlimited assessment that may expand without notice.
In more detail
How each benefit works in practice
Technical expertise
14 years of workshop practice
The workshop has operated since 2011. The lead technician trained in Switzerland and has worked with mechanical calibres from Japanese, Swiss, and German manufacturers across that period. Complication work — chronograph, GMT, annual calendar, moonphase — requires familiarity with the specific subsystems of each module, not only with general movement servicing.
- Swiss-trained lead technician
- Experience across Japanese, Swiss, and German calibres
- Complication recalibration capability
- Multi-day observation cycles for verification
Process transparency
Defined steps, written at each stage
The full service follows a defined sequence: opening and photography, ultrasonic cleaning, lubrication using calibre-specified materials, replacement of standard wear parts where needed, regulation across positions, case reassembly, and pressure testing. Each stage is documented. The owner receives a written summary when the watch is collected.
- Photographic documentation of components
- Ultrasonic cleaning stage included
- Regulation across multiple positions
- Written service summary at collection
Owner communication
Clear, timely, in plain language
The diagnostic report is written to be understood by the owner, not only by another technician. Findings are described in plain terms alongside the technical detail. When the report identifies options, it explains the reasoning behind each one so the owner can make an informed decision about what to do next.
- Reports written for owners, not technicians
- Options explained with reasoning
- Contact by phone or email during service period
- In-person discussion available at the workshop
Pricing and value
Stated before work begins
Service prices are stated in Thai Baht and confirmed before any work proceeds. The diagnostic service at ฿4,300 is a standalone engagement — it does not commit the owner to further work. The full service at ฿9,800 covers the complete process described, not a subset of it. Complication recalibration at ฿15,000 reflects the additional observation time required for multi-function modules.
- Prices stated upfront in Thai Baht
- No deposit required before diagnostic report
- Payment collected at collection, after work is complete
- Pressure testing and documentation included in price
Measured outcomes
Performance recorded and reported
The performance of the movement is measured after service. The written summary includes the measured rate — how the watch is performing against its specification — across the positions tested. For complication recalibration, the observation cycle gives a picture of consistency over time, not only a snapshot from the moment of assembly.
- Measured rate recorded in service summary
- Multi-position regulation for automatics
- Multi-day observation for complication work
- Result verifiable by owner at collection

Distinctive features
What siamchra offers that is not standard
01.The diagnostic report as a standalone service
Most workshops treat assessment as part of a service quotation, not as an independent deliverable. siamchra offers the condition report as a service in its own right, with its own price, at ฿4,300. The report belongs to the owner and may be used however they choose — including to seek a second opinion or proceed elsewhere.
02.Multi-day observation for complication work
Complication recalibration at siamchra includes a multi-day observation cycle after the technical work is complete. This period is used to verify consistent performance across the full function range of the module, not only a snapshot check immediately after assembly.
03.No courier-only model
The workshop maintains a permanent address where owners can visit, leave a piece, and collect in person during opening hours. There is no logistical intermediary between the owner and the technician who works on the piece.
04.Controlled environment during disassembly
Movements are opened in a filtered workspace. Particulate contamination is managed at the point of disassembly rather than relying only on post-cleaning to address what enters the movement during opening — a distinction that matters for the service longevity of the piece.

The diagnostic report is the first reasonable step
Before committing to a full service, it is worth knowing what condition the movement is actually in. The written report gives you that information and keeps all options open.
