Our Story

A Workshop Built on Patience

Pim started with a simple conviction: watches deserve the same care they were built with. Sixteen years later, that hasn't changed.

Who We Are

Pim Watch Repair & Restoration

Pim opened in Ratchathewi in 2009. The founding idea was modest: to offer Bangkok a place where watches could be assessed honestly, serviced carefully, and returned to their owners in better shape than when they arrived.

The workshop handles three kinds of work — battery and seal service for quartz pieces, complete mechanical overhauls for daily-rotation watches, and patient vintage restoration for pieces with history behind them. Each service follows the same unhurried approach.

Customers come from across Bangkok and, increasingly, from outside Thailand. Many have tried other workshops and arrived here looking for a different experience: one where someone explains what a watch needs in plain terms, photographs document the process, and nothing is done without the owner's agreement.

Our Approach

The Setting Lever Philosophy

The setting lever is the small internal component that allows a wearer to adjust the time with a gentle push of the crown. It is easy to overlook, but without it the watch cannot be set. Pim's work is guided by that idea — thoughtful, deliberate action where the small things matter.

This means no unnecessary work, no inflated assessments, no cosmetic changes without discussion. For vintage pieces in particular, the aim is conservation rather than transformation — preserving the character of a watch rather than polishing it into something it wasn't.

What drives us

Honest assessments before work begins
Clear timelines, kept to where possible
Photographs accompanying restoration work
Patina conserved, not erased
No pressure to proceed after assessment

The People

The Workshop Team

Small, experienced, and focused on getting things right. Each member of the team handles a specific area of the work.

Pim Prasomsup

Lead Watchmaker

Sixteen years of movement repair across quartz and mechanical calibres. Pim oversees every job that leaves the workshop and handles all vintage restoration personally.

Nattapong Kriengkrai

Movement Technician

Specialises in complete service work for mechanical movements. Nattapong joined the workshop in 2015 and handles the majority of timing regulation and mainspring assessment.

Siriwan Wiriyaphan

Client Liaison

Handles enquiries, assessment appointments, and progress updates. Siriwan makes sure customers know where their watch is and what's happening to it at every stage.

How We Work

Standards We Hold Ourselves To

Written Assessments

Every watch that comes in receives a written note of what it needs before any work begins. Nothing proceeds without your agreement in hand.

Proper Tooling

Work is carried out with appropriate horological tools. No improvised methods, no substitution of correct parts with approximate alternatives.

Quality Lubricants

Movement oils and greases are sourced from established horological suppliers and are stored and applied according to manufacturer specifications.

Secure Custody

All watches in our care are logged on arrival, stored in a secured area, and handled only at the designated workbench during service hours.

Timing Verification

Mechanical movements are tested on a timing machine across multiple positions before being signed off. Results are noted and can be shared with the owner.

Water Resistance Checks

Where applicable and after seal replacement, watches are tested for water resistance using appropriate pressure equipment before being returned.

Bangkok Watch Repair with a Methodical Approach

Ratchathewi has long been a practical, working district — a place where things get done without fuss. Pim fits that character. The workshop doesn't advertise urgency or make claims about speed. What it offers instead is a reliable process: look at the watch, explain what it needs, do only that work, and return it in good running order.

For mechanical movements, this means a full clean of the plate and bridges, fresh oil in each jewel and pivot, careful inspection of the balance staff and pallet fork, and regulated timing across multiple positions. For vintage pieces, it means conserving what is worth keeping and discussing everything else with the owner first.

Restoration Work That Respects a Watch's Age

Vintage watches acquire a particular character over decades — a dial that has mellowed, lume that has shifted colour, a case with the small marks of everyday use. These are not defects. They are evidence of a life lived alongside someone.

Pim's restoration work starts from the assumption that this character is worth keeping. Movement overhaul, yes — a vintage calibre running accurately is not a compromise. But case polishing, dial refinishing, and similar cosmetic work happen only at the owner's specific request and with full discussion of what will be lost as well as gained.
