Three Services, One Workshop
Measured Work for Watches That Matter
Three clearly defined services, each matched to a specific set of needs — from a post-holiday salt-water clean to a full marine chronometer calibration before extended sea use.
← Back to HomeEach service at Aroon Tempus begins with an assessment of what the watch actually needs. We do not apply a standard package to every piece that arrives. A watch returning from a week of snorkelling has different requirements from one that has been worn daily for three years without service — and a marine chronometer being prepared for an extended voyage has different requirements again.
The assessment informs which of the three services is appropriate. In most cases, the work required is clear from the owner's description. Where there is uncertainty — particularly with pieces that have an unknown service history — a brief inspection is carried out and discussed with the owner before anything proceeds.
All work is documented. The condition report issued with every returned watch describes what was inspected, what was replaced, what was tested, and what is worth monitoring at the next service interval. This is a consistent practice, not an optional add-on.
Service One
Beach-Wear Watch Refresh
4,500 THB
A short-form workshop visit for watches that have been used in salt-water environments. The service covers gentle external cleaning, removal of accumulated salt from lug recesses and bracelet links, gasket inspection and renewal where appropriate, crown tube checks, and a pressure test where the case construction supports one. Suited to dive watches in regular use, daily-wear sports watches, and pieces returning from a long beach holiday.
- Gentle external cleaning of case, lugs, and bracelet links
- Salt deposit removal from recesses
- Gasket inspection and renewal where appropriate
- Crown tube inspection
- Pressure test where case construction supports it
- Short written note on completion
Process
Typical turnaround: 5 – 7 working days

Mechanical Servicing with Strap Refresh
8,200 THB
A combined visit that pairs a full mechanical movement service with a strap and bracelet refresh. The movement is disassembled, cleaned, lubricated, and regulated; the case and bracelet are gently cleaned, with optional light polishing referred back to the owner; and a new strap or fresh links can be fitted on request. Suited to watches in regular daily wear that have been overdue for attention. A written summary describes the movement's behaviour before and after the visit, along with notes on the case and strap condition.
- Full movement disassembly and ultrasonic cleaning
- Lubrication with appropriate horological oils
- Timing regulation — rate and amplitude measured
- Case and bracelet external clean
- Optional new strap or bracelet links on request
- Written summary of before and after behaviour
Process
Typical turnaround: 2 – 3 weeks

Service Three
Marine Chronometer & Diver Calibration
14,500 THB
A specialist service for marine chronometers, dive watches with depth ratings, and tropical-use field watches. The work includes case integrity inspection, gasket and o-ring renewal, helium escape valve check where fitted, full movement service, regulation across positions, depth-rated pressure testing in the workshop's certified chamber where applicable, and a written depth and timing report. Suited to owners who would like a clear written record of their watch's calibrated behaviour before extended sea use. Watches typically spend four to six weeks in the workshop.
- Full case integrity inspection
- All gaskets and o-rings renewed
- Helium escape valve checked where fitted
- Full movement service (disassembly, clean, lubrication)
- Multi-position timing regulation
- Certified depth-pressure test with written result
- Written depth and timing report
Process
Typical turnaround: 4 – 6 weeks

Practices followed as standard on every watch that passes through the Aroon Tempus workshop.
Secure Intake & Logging
Each watch is assigned a job number on arrival, with a dated visual condition record. Watches are stored individually throughout.
Humidity-Managed Storage
Parts cleaned and disassembled are kept in a low-humidity environment during drying phases to prevent new corrosion forming before reassembly.
Grade-Appropriate Lubrication
Lubricants are matched to the specific movement and its components. Greases and oils are rotated and not used beyond their recommended working life.
Timing Verification
Rate is checked using a timing machine before and after service. Any movement outside acceptable parameters is addressed before the watch is returned.
Owner Approval Before Extras
If inspection reveals components needing replacement beyond the agreed service scope, the owner is contacted and the work proceeds only with explicit agreement.
Written Report on Completion
A condition report accompanies every returned watch. It describes the initial state, the work completed, and any observations for future servicing.
