Somchai Thaweesuk

Bangkok · Automatic Movement Tune

My grandfather's Seiko 5 had been running about two minutes slow each day. Krit assessed it and said the mainspring was showing early fatigue along with the expected lubricant dry-out. The service took twelve working days. When I collected it, he handed over a printed timing sheet — which I didn't expect. It's now running to within about four seconds a day. I appreciated that he didn't oversell it or make promises about what the result would be beforehand.

Priya Patel

Bangkok (expat) · Water-Resistance Check

I brought in a dive watch before a trip to Koh Tao. The assessment found one of the crown gaskets had cracked — I wouldn't have known without checking. The reseal and pressure test took four days. The workshop is not large and you book by appointment or drop in, which suits me. I knocked one star off only because parking on that stretch of Sukhumvit is awkward, which isn't really their fault. The work itself was exactly what I needed.

Nattapon Watcharapong

Nonthaburi · Heirloom Revival

My father's Omega Constellation had not run in over twenty years. I wasn't sure it was worth the trouble but I brought it in anyway. Nattaya assessed it and explained that the movement was sound but that one jewel pivot had worn significantly. She sourced a period part — it took longer than expected, about six weeks total — but she kept me informed throughout. The watch now looks and runs well, and critically still looks like it did when my father wore it. The patina on the dial was preserved completely.

Lalita Mahathorn

Silom, Bangkok · Movement Tune

I have been to four different watch counters in Bangkok over the years and the experience is always the same — they take the watch, you wait, they hand it back with a verbal 'all good' and that's that. Chronohaven is different. Pramot showed me the timing results before and after, and explained what had caused the deviation. Small detail, but it made me feel the price was for something real rather than just labour.

Ravi Sharma

Sukhumvit · Water-Resistance Check

Quick and straightforward. I only needed the water-resistance check and it was done in three days. The assessment found the caseback seal was fine but the crown tube gasket had aged. They replaced it and ran the pressure test. Simple service, explained clearly, priced as advertised. I'll bring my other watch in when it needs a service.

Wanchai Charoenpong

Thonglor · Heirloom Revival

A Longines dress watch from my uncle — stopped running, bracelet clasp broken, crystal scuffed badly. I did not expect much given the watch's age. Krit was honest at the assessment that the movement overhaul was straightforward but that sourcing a bracelet clasp of the right period would take time. It did — five and a half weeks — but the result is a watch I now wear regularly. He was also honest that polishing the case to a high shine would remove evidence of age and asked what I preferred. I chose to keep it light and I'm glad I did.

Case Studies

Three Watches in Detail

A closer account of what the work actually involved in three representative cases.

Case 01: 1968 Citizen Automatic — Heirloom Revival

Duration: 7 weeks · Service: Heirloom Revival

Challenge

The watch had not run in at least fifteen years. The bracelet end links were missing. One luminous marker had detached from the dial. The movement turned over but stopped after a few minutes of wear.

What Was Done

Full movement disassembly and ultrasonic cleaning. The mainspring was replaced and the automatic rotor bearing rebuilt. End links were sourced from a Japanese parts archive. The detached marker was reset with period-correct adhesive. Crystal replaced with a period flat mineral.

Outcome

Running at +6 seconds per day in a dial-up position. Power reserve restored to approximately 40 hours. Owner described it as looking "like it should rather than like it's been fixed."

"I thought I was being sentimental even bringing it in. I was wrong."

Case 02: ETA 2824-2 Daily Wearer — Movement Tune

Duration: 11 working days · Service: Automatic Movement Tune

Challenge

Running approximately +35 seconds per day. The watch was four years past its last service. No visible damage but timekeeping had degraded noticeably over six months.

What Was Done

Movement removed and disassembled. All components ultrasonically cleaned and dried. Escapement pallet stones inspected under magnification — wear acceptable. Lubricated with Moebius oils appropriate to each component. Regulation performed over three days with timing machine monitoring.

Outcome

Timing at handover: +3 seconds/day dial up, +5 seconds/day crown down. Amplitude 285° (healthy range for this calibre). Owner received printed timing card with these figures.

"The printed sheet was an unexpected touch. Useful to have for the next service."

Case 03: Orient Diver — Water-Resistance Check

Duration: 3 working days · Service: Water-Resistance Check & Reseal

Challenge

Owner planning a diving trip to the Andaman Sea. Watch was rated 200m from manufacture but had not been checked in three years. No visible seal deterioration but owner wanted confirmation before submersion.

What Was Done

Crown tube, caseback, and crystal gaskets inspected. Caseback gasket showed minor compression set — replaced. Crown tube gasket in good condition — retained. Dry pressure test run at 20 bar. Case resealed and test repeated.

Outcome

Pressure test passed at 20 bar with no detectable leak. Owner left with a written test result and a note that the next check should be done within two years given tropical climate.

"Exactly what I needed before the trip. Quick, clear, and documented."
