Somchai Kliangklao

Bangkok · Collector

I brought in a Valjoux 7750 that had not been touched in twelve years. The assessment was thorough — they noted three worn pivots and a cracked gasket before I agreed to proceed. The timing report they provided after service showed the watch running within +4 seconds per day. The summary document was something I had never received from a workshop before.

My grandmother's Omega Seamaster needed work and I was nervous about leaving it anywhere. The team photographed it on intake, sent me a written scope before touching anything, and returned it with a full service record. The communication in English was clear throughout. Four months on and it is keeping time better than it did when I was a child wearing it to school.

Phirun Thongsuk

Chiang Mai · Casual wear

I sent two quartz watches by registered post after speaking with them first. They confirmed receipt with photographs, replaced both batteries, noted that one crown seal was beginning to wear, and returned the watches with a written note. Slightly longer than the quoted 3 days due to shipping, but no issues with the service itself.

British, Bangkok · Collector

Khun Arun personally assessed my Lemania 2310-based chronograph. He explained the lever arrangement and why the rewind crown had been sticking before he confirmed the scope. The project took six weeks and cost more than I had initially expected — but the detailed project log and condition photographs he sent before I collected it made the decision easy. That watch is now running correctly for the first time in years.

Bangkok · First-time client

I had never taken a watch to a specialist before and was not sure what to expect. The intake process was clearly explained, the assessment note was written in English so I could share it with my father abroad, and the turnaround on a battery and gasket service was two days. I appreciated that they did not pressure me to do more than was needed.

Hiroshi Matsuda

Japanese expat · Bangkok

A Grand Seiko that I have worn for fifteen years was serviced here last month. The timing report showed +2/−1 seconds across five positions, which for that movement at that age I consider excellent. The written summary was precise — the kind of record I would expect from a Japanese service centre. Not common at this level in Bangkok.

Three Service Stories

Vintage Rolex Calibre 1520 — Standard Service

Client: Bangkok collector · May 2025

Challenge

A 1968 Rolex with calibre 1520 had not been serviced in over fourteen years. The owner reported gradual timekeeping decline — losing around 45 seconds per day. The watch held significant sentimental value; the owner was cautious about who handled it.

Service Approach

Full disassembly with condition photograph at each stage. The mainspring showed slight set; it was replaced. Worn cannon pinion addressed. All components cleaned, lubricated to factory specifications. Timing measured over four days post-reassembly to confirm stability.

Outcome

Watch returned running at +6 seconds per day — within the factory tolerance for the calibre. Written service summary included detailed timing data across six positions. Owner noted this was the most thorough documentation they had received for any watch in 30 years of collecting.

Turnaround: 16 days

Heuer Carrera Ref. 1158 — Complication Restoration

Client: Expatriate collector · April 2025

Challenge

A 1970s Heuer Carrera with Valjoux 7734 movement. The chronograph start/stop function had become unreliable — activating and stopping inconsistently. The case showed wear consistent with decades of use. The owner wanted both mechanical and cosmetic work addressed.

Service Approach

Full chronograph disassembly with mapping of cam and lever positions. Column wheel and lateral clutch inspected; worn return hammer spring replaced with sourced original-specification part. Case and bracelet refinished to preserve period-appropriate finish. Photo documentation of all stages.

Outcome

Chronograph function fully restored — consistent start, stop, and reset. Timing report showed +8 seconds per day on base movement. Cosmetic work preserved the patina while addressing surface corrosion. Project log with 34 photographs provided at collection.

Turnaround: 5 weeks

Longines VHP Quartz — Diagnostic & Battery

Client: First-time postal client · May 2025

Challenge

Client based in Chiang Mai contacted us by email with a Longines VHP that had stopped. Uncertain whether the issue was battery, movement, or a circuit fault. Sent the watch by insured courier after pre-arrangement.

Service Approach

Intake photograph sent to client on arrival. Assessment confirmed flat battery and a worn crown seal. Battery replaced with correct silver oxide cell; crown seal replaced. Basic water resistance check confirmed seal integrity. No circuit or movement faults found.

Outcome

Watch returned by insured courier within 5 days of receipt. Written note explained findings, the crown seal condition observed, and suggested monitoring timeline. Client reported the watch keeping accurate time and noted the clear written explanation was more than they had expected for a battery visit.

Turnaround: 3 working days
