A watch worth keeping
deserves careful hands.
hairspringf is a small repair workshop on Thanon Khao San. We work on straps, movements, and cases — taking the time each piece needs, without shortcuts.
What we do
Three services, done properly.
Strap & Bracelet Refresh
Cleaning, resizing, and refitting of leather, rubber, or metal bracelets, with worn spring bars renewed as needed. Link adjustment, clasp check, and a gentle bracelet clean included. Most jobs are done within a day.
- Spring bar renewal
- Link removal or addition
- Clasp and buckle check
Chronograph Servicing
Full servicing of the chronograph works alongside the base movement. Pusher function checked, reset behaviour adjusted. Suited to multi-function pieces whose stopwatch action has grown stiff or lost accuracy. Turnaround three to four weeks.
- Column wheel or cam inspection
- Sub-dial function testing
- Timing review and regulation
Complete Overhaul & Refinish
Full movement overhaul combined with hand refinishing of the case and bracelet. Brushing and polishing to original lines, crystal renewal, and complete water-resistance work. Four to eight weeks turnaround.
- Full movement strip and clean
- Case and bracelet hand refinishing
- Water-resistance pressure test
Why hairspringf
Unhurried work. Considered results.
Transparent Assessment
We look at every piece before quoting. You receive a written summary of what the watch needs and what it will cost, with no surprises after the fact.
Hands-On Craft
Every movement is handled by the same watchmaker from intake to return. No assembly-line handoffs; one person follows each job through to completion.
Six-Month Workmanship Cover
Our labour carries a six-month cover period. If an issue traced to the repair surfaces within that window, we address it at no additional charge.
Realistic Timelines
We quote turnaround times we can keep. Strap jobs typically same day; movement work three to eight weeks depending on scope.
Central Bangkok Location
The workshop sits on Thanon Khao San — accessible by tuk-tuk, taxi, or foot from the Phra Athit Chao Phraya pier. Walk-ins are welcome during opening hours.
Full Service Record
Every completed job comes with a written service record noting the work performed, parts replaced, and timing figures measured on the timegrapher.

Common questions
Before you drop off your watch.
Do you service all watch brands?
We work on most mechanical and automatic movements regardless of brand. Highly complex proprietary calibres — certain integrated chronograph movements in particular — may need to be referred to a brand service centre. We will tell you honestly at the assessment stage if that is the case.
How do I get a quote?
The most straightforward way is to bring the watch in. We examine it and prepare a written quote at no charge. If you are outside Bangkok, you can also send photos through the contact form and we can give an initial estimate, with the final figure confirmed once the watch is in hand.
How long does a complete overhaul take?
A full movement overhaul with case refinishing typically takes four to eight weeks. The range depends on parts availability, the condition of the movement, and current workshop volume. We provide a specific estimate when we accept the job and keep you updated if anything changes that timeline.
What does the strap service include?
The strap and bracelet refresh covers cleaning, link adjustment or removal, new spring bars where the existing ones are worn, and a clasp or buckle check. For metal bracelets we also clean between the links. Most strap jobs are ready the same day or the following morning.
Do you use original manufacturer parts?
Where genuine parts are available and within reasonable cost, we use them. For watches where OEM parts are no longer supplied or are disproportionately expensive, we will discuss the alternatives with you before proceeding. We do not fit non-original parts without the owner's knowledge and consent.
Is my watch insured while it is with you?
Watches in our care are covered against loss or damage caused by the workshop. We ask that owners declare an approximate value at drop-off so our records are accurate. For pieces of significant value, we recommend owners maintain their own insurance policy as well.
