About Horolune
A Workshop That
Works at the Pace of the Work
We opened Horolune because we believed Bangkok deserved a watch repair workshop that put the quality of the work before the speed of the turnaround. Fifteen years on, that hasn't changed.

Started by One Watchmaker. Still Run That Way.
Horolune opened on Sukhumvit Road in 2009. The founder, Khun Wanchai, had spent a decade at a Swiss-trained watchmaking school in Chiang Mai before moving to Bangkok with a set of tools, a timing machine, and a workbench he built himself.
The name is a compound of horology — the study of timekeeping — and lune, the French word for moon, a nod to the moon-phase complications that first drew him to mechanical watchmaking. It felt right: patient, cyclical, and not in a rush to arrive anywhere.
Over the years the workshop expanded to a small team of two technicians, but the approach hasn't shifted. Each watch is assessed by hand. Each service report is written by the person who did the work. We don't sub-contract to larger service centres, and we don't treat a collector piece the same way we'd treat a budget quartz.
Most of our work comes through word of mouth from customers who brought in a grandfather's automatic and were pleased enough to come back when their own daily wearer needed attention. That kind of continuity matters to us.
Our Mission
Care Over Convenience
Our aim is straightforward: return each watch to the person who brought it in running more accurately and with a clear record of what was done inside it. We're not trying to be the fastest workshop in Bangkok. We're trying to be the one you trust.
Transparency About the Work
Written condition reports go out with every mechanical service. If a part is worn, we name it and explain what it means for the movement's long-term performance. If a part doesn't need replacement, we say so rather than pad an invoice.
Heritage Piece Sensitivity
A 1965 dress watch is not the same job as a modern sport model. We adjust our approach — and the tools we reach for — based on what the piece is, what it means, and what original specifications we can work from.
The Workshop Team
Two Technicians, One Standard
Wanchai Srisuk
Founder & Lead Technician
Swiss-trained watchmaker with 20 years of hands-on experience in mechanical movement servicing, regulation, and heritage restoration. He assesses every piece that enters the workshop.
Nattaporn Phitak
Workshop Technician
Trained in Bangkok and specialised in quartz servicing, strap and bracelet work, and water-resistance testing. Also handles case polishing and bracelet refinishing on restoration projects.
Anchalee Kaewsri
Client Liaison
Manages intake assessments, written condition reports, and customer communication. Anchalee ensures that the detail recorded in the workshop is communicated clearly to the person who owns the watch.
Workshop Protocols
The Standards We Hold Ourselves To
Swiss-Grade Lubricants
We use only Moebius and Nye lubricant lines, applied to manufacturer-specified points and quantities. The lubricants we stock are stored at controlled temperature to preserve viscosity.
Timing Machine Regulation
Every mechanical service ends with multi-position regulation on a Witschi timing analyser. The printed result accompanies the written condition report.
Pressure Testing
Water-resistance work is verified with a dry-air pressure test at the case's rated depth before handback. We do not rely on visual gasket inspection alone.
Ultrasonic Cleaning
Movement parts are cleaned in a multi-stage ultrasonic bath with dedicated solutions for different component materials. No part goes back into assembly with residual old lubricant.
Written Documentation
Every movement service results in a written report noting pre-service condition, work performed, parts replaced if any, timing results, and any components flagged for future monitoring.
Secure Custody
Every piece in the workshop is catalogued with photos at intake. Watches are stored in a locked cabinet when not on the bench, and handed back only to the person who brought them in.
What We Stand For
Watchmaking Values in a Bangkok Workshop
Watch repair in Bangkok is not a shortage of options. There are market-stall technicians who will change a battery in two minutes, and there are authorised service centres with long queues and longer wait lists. Horolune sits between those two worlds — a private workshop where mechanical work is taken seriously, but where you don't need a manufacturer's account number to get a thoughtful service.
We work on pieces that matter to the people who own them. A watch given at retirement. A sports watch bought on a first salary. A complicated dress watch that belonged to a parent. Those pieces deserve careful handling and honest communication about what's inside them.
Our location on Sukhumvit Road keeps us accessible to Bangkok's international community and to Thai collectors alike. We work in English and Thai, and we've built relationships with suppliers in Switzerland and Japan that allow us to source parts for movements that aren't easy to find locally.
Horolune is not trying to be a chain. We have two benches, two technicians, and a clear sense of what kind of work we want to do well. If your watch needs the kind of attention we can give it, we'd be glad to take a look.
