A Workshop Shaped by the Coast
Suriya Time was built around the particular demands of watches that spend time near salt water. We work carefully, document thoroughly, and do not rush.
Return to HomeHow Suriya Time Came to Be
Suriya Time began as a practical response to a gap that was difficult to ignore. Phuket has a large population of divers, sailors, and long-term residents who spend significant time around the Andaman Sea — and their watches show it. The combination of salt water, humidity, and tropical heat is hard on any timepiece, but it is particularly damaging to a watch that has not been properly maintained.
The workshop was established on Bangla Road in Patong to be close to the places where marine activity is concentrated. Our approach from the beginning has been methodical: inspect carefully, document what we find, discuss findings with the owner before proceeding, and use methods appropriate to each piece rather than applying a generic process to everything that comes through the door.
We focus on three areas of work that reflect what Phuket-based watch owners actually need: diver's service and pressure testing, restoration of pieces affected by coastal corrosion, and specialist work on older marine chronometers and vintage dive watches. Each of these requires a different body of knowledge, and we have built our practice around all three.
The name Suriya — Thai for sun — reflects both our location and the nature of the work: patient, steady, and present. A watch repaired here is one that has been given proper attention.
What We Stand For
-
Transparency Before Action
We share what we find in writing before undertaking any significant work. Owners decide what proceeds.
-
Documentation as a Standard
Every appointment generates a written record. For restoration work, that record travels with the watch.
-
Unhurried Work
We schedule appointments with enough time to do the work properly. Complexity does not get compressed into a shorter slot.
-
Respect for Original Character
Particularly for older pieces, we preserve what can be preserved and consult before replacing what cannot.

The People at the Bench
Suriya Thongsri
Workshop Principal
Over two decades working on mechanical watches, with a particular focus on marine instruments developed during fourteen years in Phuket. Trained initially in Bangkok before specialising in diver's watches and pressure-rated timepieces.
Pim Kaewchai
Movement Technician
Specialises in vintage movement service, with experience across Swiss and Japanese calibres from the 1950s to the 1980s. Responsible for the documentation process and parts sourcing for restoration appointments.
Nattapong Wongsa
Case & Restoration Specialist
Handles case-side work including polishing, corrosion treatment, and gasket replacement. Conducts pressure testing and maintains the workshop's sealing and testing equipment.
How We Work
Each standard below reflects a practical decision about how this kind of work should be conducted, not a marketing aspiration.
Calibrated Pressure Testing
Pressure testing equipment is calibrated regularly. Results are tested to the original rated depth of each model, not a generic figure.
Written Service Record
Every job produces a service ticket recording findings, parts used, and test results. Restoration work additionally receives a documented folder.
Gasket Standards
All gaskets used meet or exceed original manufacturer specifications. Crown, case-back, and pusher seals are replaced as a set, not selectively.
Condition-Led Approach
Movements are opened only where the inspection findings support it. We do not apply a standard strip-and-service to every watch that arrives.
Owner Consent Before Proceeding
For restoration appointments, significant findings are shared with the owner before any parts are sourced or replaced. Work scope is agreed in advance.
Original Parts Retained
Parts removed during service or restoration are returned to the owner with the watch. We do not dispose of original components without permission.
Marine Timepiece Work in a Coastal Setting
Working on watches in Phuket is different from doing the same work in a landlocked city. The air carries salt. Humidity sits consistently above what most manufacturers design their products to tolerate over long periods. Watches worn by divers accumulate pressure cycles that accelerate wear on seals and gaskets. These are not edge cases — they are the normal conditions for a large proportion of the watches we see.
Our diver's service appointment was designed around this reality. The pressure test is not an optional add-on: it is the primary quality measure. A watch that looks fine externally but fails a pressure test at a fraction of its rated depth is not a watch that should go back into the water. We record the result on the service ticket so the owner has a reference point for the next service interval.
Salt-air restoration is a less standardised appointment, because the degree of corrosion varies considerably between pieces. Some owners bring watches that have been sitting in a coastal environment for years without attention; others notice early pitting and act before it progresses. Either situation is addressable, though the scope of work differs. Our approach is to assess the piece thoroughly, share the findings in writing, and then discuss what is worth treating versus what falls within the owner's tolerance.
Vintage diver and marine chronometer work requires a different mindset entirely. The goal with a 1960s watch is not to make it look new — it is to make it run well while preserving the character that gives it value. Period bezels, original crystals, and correct-era indices are sourced where they remain available. Where they are not, we discuss appropriate alternatives with the owner before sourcing anything. The documentation produced during this kind of restoration becomes part of the piece's ongoing record.
Suriya Time is a small workshop, and we schedule accordingly. We do not take on more work than can be done well in a given period, and we are straightforward about timelines from the outset of each appointment.
