Three Services

The Work We Do
and How We Do It

Three focused services covering the most common and most involved watch repair needs. Each follows the same principle: open, assess, communicate, complete.

Our Method

How Every Job Begins

01

Intake

We log the watch with owner details, a description of its condition, and the agreed service scope. Nothing is opened until intake is complete.

02

Assess

The case is opened and the movement or seals assessed. If the findings differ from what was expected, we contact you before proceeding.

03

Service

The agreed work is carried out — cell replaced, gaskets renewed, or calibre cleaned and lubricated — using appropriate tools and grade-specific lubricants.

04

Return

The watch is returned with a verbal or written summary depending on scope. For calibre work, a service note is included.

Battery and quartz service

Service 01

Battery & Quartz Service

฿3,400

Replacement of the cell, gasket inspection, and a function check for quartz watches. We test the movement draw to confirm a healthy power reading before returning the piece. A straightforward visit, usually completed the same day, with a note on any wear we observe.

What is Included

  • Cell removed and replaced with correct specification
  • Crown and caseback gasket visually inspected
  • Movement draw measured with reference meter
  • Timekeeping confirmed over short run period
  • Condition notes provided on any observed wear

Process

  1. Case opened and existing cell removed
  2. Contacts cleaned and new cell seated
  3. Movement draw tested for healthy current reading
  4. Case closed, running time confirmed
  5. Watch returned same day in most cases
Enquire Typical: same day
Water-resistance review

Service 02

Water-Resistance Review

฿6,800

A pressure assessment of seals and gaskets for watches intended to handle splashes or swimming. We replace worn gaskets and re-seat the caseback, then confirm the rating where the case allows. Helpful before a holiday or rainy-season travel.

What is Included

  • Dry-air pressure test to watch's stated bar rating
  • Crown tube gasket and caseback O-ring replaced
  • Caseback re-seated to correct torque
  • Post-assembly re-test confirms seal integrity
  • Case condition noted in handover report

Process

  1. Initial pressure test on the assembled watch
  2. Caseback opened, old gaskets removed
  3. New gaskets fitted and case reassembled
  4. Second pressure test confirms new seal holds
  5. Case condition documented and watch returned
Enquire Typical: 1–2 days
Chronograph calibre service

Service 03

Chronograph Calibre Service

฿11,500

Detailed servicing of stopwatch complications, including the levers and resetting mechanism that need careful adjustment. We clean and lubricate the calibre and confirm each pusher functions cleanly. Carried out over a few days with a written summary of the work.

What is Included

  • Full disassembly of base movement and chronograph layer
  • Ultrasonic cleaning of all metal components
  • Column wheel and coupling clutch inspected and adjusted
  • Calibre-specific lubrication to all relevant points
  • Each pusher and reset mechanism confirmed clean
  • Timing machine rate check in multiple positions
  • Written service summary returned with the watch

Process

  1. Movement removed and photographed before opening
  2. Full disassembly, components sorted and cleaned
  3. Escapement and chronograph layer reassembled with fresh lubricants
  4. Rate checked on timing machine, regulation as needed
  5. Pushers and reset tested repeatedly before casing
  6. Service note compiled, watch returned with paperwork
Enquire Typical: 4–7 days

Shared Standards

Protocols Across All Services

Case Protection Protocol

Bracelet and case are covered during movement work. No polishing or case modification is carried out without explicit request.

One Technician per Job

Responsibility for a watch is assigned to one person from intake to return. No mid-service handoffs.

Secure Storage

Watches left for multi-day work are tagged and stored securely on-site. Intake record includes owner contact and agreed scope.

Grade-Specific Lubricants

We stock the lubricant grades specified by the calibre manufacturer and use them at the correct application points.

No Surprise Costs

Any cost beyond the agreed scope is discussed and approved before it is incurred. You are in control of what is spent.

Honest Scope Assessment

If a watch requires work we cannot carry out properly, we say so. Manufacturer-specific parts or proprietary tooling requirements are explained at intake.

Pricing

Clear, Fixed Service Rates

All prices in Thai Baht. Additional parts quoted separately and approved before ordering.
