Bangkok, Thailand

I brought a 1960s Omega Seamaster that had belonged to my father. It had not run for about fifteen years. The workshop examined it, gave me a clear written estimate, and then rang me when they found the mainspring needed replacing to confirm I was happy to proceed. That kind of communication was not something I had encountered before with repairs. The watch came back running well, with its original dial untouched. The condition report was thorough.

I sent a two-day marine chronometer from Sweden — a Kullberg from the early 1900s that had stopped some decades ago. Finding someone willing to work on it in Europe was proving difficult; most workshops I contacted declined outright. Ayutthaya Chronos were honest about the timeline — nearly three months — and sent photographs at each stage of the disassembly and reassembly. The rate is now within acceptable limits. I could not be more satisfied with the communication and the outcome.

Ayutthaya, Thailand

I went in to have a simple strap replaced on an older Seiko I had been wearing for years. The job was done carefully and the spring bars were replaced without being asked — which I appreciated since the existing ones were quite tired. The price was fair. The only small note is that I would have liked a wider range of strap options in thinner widths, but what was available was good quality. I'll go back when the watch needs a full service.

Chiang Mai, Thailand

I had a military-issue watch from the 1950s — a Longines — that needed movement work. I was concerned they might over-restore it and lose the character. Wanchai understood immediately what I was trying to preserve and was quite explicit that the case would not be polished without my agreement. It came back exactly as it should have: the movement cleaned and running accurately, and the exterior looking its age. That is precisely what a piece like this needs.

Nonthaburi, Thailand

My grandmother's dress watch — a small Tissot — had a cracked crystal and had not been serviced in many years. I was nervous about handing it to anyone. The assessment was detailed, the timeline was realistic, and the watch was returned with the original crown intact and the movement running smoothly. The dial was cleaned very carefully. I was kept informed throughout. A straightforward, unhurried experience.

I couriered a pocket watch from Singapore — a vintage IWC that had been in the family for three generations. The workshop contacted me promptly on receipt and provided a thorough assessment within a few days. The movement work took about six weeks. The rate has been consistent since I received it back. Communication was good throughout, though I would have appreciated one additional update mid-service. The end result was worth the wait.

Three pieces, three journeys

Case Study — Heritage Wristwatch Restoration

The Challenge

A 1947 Rolex Dateback — not a Datemaster but a genuine rarity — arrived from an owner in Bangkok who had inherited it and found it running some eight minutes per day fast. A previous workshop had attempted a service but the piece had not improved. The owner was understandably hesitant about further work.

The Work

Full disassembly revealed contaminated lubricants and a worn balance staff — the previous service had not addressed either. The balance staff was sourced through a vintage parts contact; the movement was cleaned and re-oiled with correct lubricants for the period. Regulation took approximately a week on the timing machine.

The Outcome

The watch was returned running at +4 seconds per day across five positions — well within acceptable parameters for the caliber. The owner received the full photographic record. Total time: seven weeks. The dial and case were not touched.

"I had given up expecting it to keep time. What came back was genuinely surprising." — Praween T., Bangkok

Case Study — Marine Chronometer Servicing

The Challenge

A box chronometer by Thomas Mercer — probably 1930s — arrived from a private collector in the UK who had acquired it at auction. It had not run in an unknown number of years. Two springs within the going train were broken, and the pivot of the escape wheel was bent. Several parts were simply unavailable through any supplier.

The Work

The bent pivot was replaced — the original wheel was used with a new pivot fitted at the bench. The broken springs were fabricated from stock material. Full disassembly, cleaning, and lubrication followed. The regulation period was extended to six weeks to establish a stable rate across temperature variations.

The Outcome

The chronometer was returned after fourteen weeks running at a consistent +1 to +2 seconds per day. The collector received 47 photographs documenting the disassembly and reassembly. The box hardware was cleaned but not refinished. Currently keeping time on a shelf in Edinburgh.

"It was the photographs that convinced me the work had been done properly. You could see every stage." — Alastair F., Edinburgh

Case Study — Strap & Bracelet Replacement

The Challenge

A 1970s Omega Genève with an original bracelet that had stretched badly over decades. The owner wanted a leather strap but was unsure what would suit an 18mm lug width on a case of that era — most modern straps look poorly proportioned on older watches.

The Work

We discussed the options and selected a narrower cordovan strap with a slight taper — more sympathetic to the 1970s case profile than a flat-cut modern strap would have been. The spring bars were replaced and the strap seated flush. The original bracelet was returned to the owner for safekeeping.

The Outcome

The fitting took just over an hour. The owner was satisfied with the proportions and has since returned for a movement service on the same watch. Turnaround on the strap: same day.

"They talked me through the options and kept the original bracelet — which I hadn't thought to ask about. Small things matter." — Kannikar W., Ayutthaya
