Three Services, Each for a Specific Need

Water resistance refreshes, accuracy tuning, and considered complication care — all with prices stated up front and work confirmed before the bench begins.

How We Work

The Same Approach for Every Job

Regardless of the service type, each job follows the same path from intake to collection. That consistency matters.

01

Intake & Examination

The watch is logged, visually inspected, and assessed before any work plan is formed.

02

Scope Confirmation

For regulated and complication jobs, the plan and cost are agreed before the bench begins.

03

Service & Testing

Work is carried out at a considered pace. Readings and tests are taken during and after.

04

Documentation & Return

A written record accompanies the watch on collection. Results, readings, and any parts noted.

Water resistance check and reseal service

Service 01

Water Resistance Check & Reseal

A focused service to refresh a watch's seals and confirm its everyday water resistance. Gaskets are renewed, the case is checked for fit, and a pressure check is carried out where the design allows. Suited to active wearers and divers who want reassurance before Bangkok's rainy season. A short report notes the resistance confirmed.

What's Included

All accessible gaskets and seals replaced

Case back, crown, and pushers checked for fit

Pressure test performed where case design permits

Written resistance report issued on collection

Process Steps

1

Visual case inspection and current seal assessment

2

Gasket replacement with appropriate specification seals

3

Pressure test to verify resistance rating

4

Report preparation and owner notification

Regulation and accuracy tuning service

Service 02

Regulation & Accuracy Tuning

Fine adjustment of a running movement to improve timekeeping across positions. The watch is measured on a timing instrument, regulated, and re-measured to confirm steadier results. Suited to mechanical pieces that run sound but drift more than the owner would prefer. A before-and-after timing sheet is included.

What's Included

Timing measurement across multiple positions

Regulator adjustment to narrow the rate variance

Post-regulation timing confirmation

Before-and-after timing sheet issued

Process Steps

1

Initial timing run across six standard positions

2

Regulator adjusted toward closer tolerances

3

Second timing run to verify improvement

4

Timing sheet prepared and watch returned

Complication service for chronographs and calendars

Service 03

Complication Service & Care

Considered servicing for chronographs, calendars, and other added functions, where extra care and parts knowledge are needed. Covers cleaning, lubrication, and function checks of the complication alongside the base movement. Best for feature-rich pieces that deserve specialist attention. The planned work and timeline are confirmed before the bench begins.

What's Included

Full complication disassembly and inspection

Ultrasonic cleaning of components

Lubrication with movement-specific oils

Function check and timing verification after reassembly

Pre-work scope and cost confirmed in writing

Process Steps

1

Initial assessment — movement and complication examined

2

Work plan and timeline shared with owner for confirmation

3

Disassembly, cleaning, lubrication, reassembly

4

Full function check and regulation

5

Service record completed; owner notified for collection

Standards

Shared Across All Three Services

Secure Watch Handling

Each piece is logged on intake and stored individually. Only returned to the owner or their confirmed representative.

Written Records

Every job, regardless of scale, leaves the workshop with a written service record covering what was done and any readings taken.

Owner Communication

Unexpected findings are flagged before any additional work proceeds. You are not presented with surprises at collection.

Correct Lubricants

Movement-specific lubricants used in the correct quantities. Not generalised oil applied as a shortcut.

Original Parts Preferred

Original components are preserved where possible. Any replacements are discussed and noted in the service record.

Scheduled Thoughtfully

Jobs are scheduled to allow the time the work actually requires — not squeezed into whatever gap exists.
