Workshop Services
Each service is carried out by hand, at a pace that the work requires. No part of the process is shortened to meet a deadline.
Hairspring & Balance Adjustment
For watches that are running fast, slow, or with positional irregularity. The technician inspects the hairspring under magnification, checks for coil sticking, magnetism, and centring issues, demagnetises the movement where appropriate, and regulates across several positions on the timing machine.
- Timing machine report before & after
- Demagnetisation where needed
- Multi-position regulation
Bracelet & Clasp Workshop
A dedicated session for bracelets and clasps that have become loose, worn, or noisy. Covers link pin and collar tube inspection, replacement of standard wear parts, clasp tension adjustment, removal of accumulated deposits from link joints, and wrist-fit sizing.
- Suited to steel & integrated bracelets
- Clasp tension restoration
- Care leaflet provided
Long-Term Calibre Overhaul
A substantive overhaul for watches whose movements have not been serviced in a decade or more. Full disassembly, ultrasonic cleaning, pivot and jewel inspection, mainspring barrel check, lubrication, regulation across positions, and pressure testing where the case construction permits.
- 5–7 weeks in workshop
- Written condition report
- Approved spare parts only
Why choose this workshop
What sets nagatima apart is its pace and its transparency — a single technician works on your watch, and you are kept informed throughout.
Work under magnification
Every hairspring inspection and pivot check is done under high-power loupe or stereo microscope. Small deviations are caught before they become larger problems.
Condition reports as standard
After each service, you receive a written record of the movement's measured state. No verbal summaries — a printed sheet you can keep with the watch.
One technician, one watch
Your watch is not passed between multiple hands. A single senior technician handles it from intake to return, with consistent familiarity throughout.
Approved spares only
Replacement parts are sourced only from brand-authorised distributors or from calibre-matched donor movements. No generic substitutes are fitted.
Clear timelines, no surprises
Estimated workshop durations are quoted upfront. If additional work is identified mid-service, you are consulted before any further steps are taken.
Central Bangkok location
The workshop is located on Ratchadamri Road in Pathumwan, accessible by BTS at Ratchadamri station. Drop-off and collection are by appointment.

Your watch deserves a second opinion.
