Our Services

Three Services, Each Done Properly

Battery care for everyday wearers, timing regulation for mechanical watches that have drifted, and full overhauls for older pieces that need unhurried attention.

Our Approach

How We Handle Every Piece

Each service at Kala Siam starts the same way: the watch is looked at carefully, its condition is noted, and you're told what we see before anything is agreed. For straightforward battery jobs this takes a few minutes. For overhauls it involves more conversation, but the principle is the same — nothing happens without your knowledge.

We don't rush. Overhauls take as long as the movement needs. Timing regulation involves running the watch on the timegrapher across positions, making fine adjustments, and verifying the result before handing it back. The work is the work; shortcuts tend to show up later.

Standards We Apply

Consistent Across All Three Services

Secure Piece Handling

All watches are stored in a locked cabinet when not on the bench. Each piece has an individual intake record from arrival to collection.

Calibre-Matched Lubricants

We stock a proper range of movement lubricants and apply them at the correct points and viscosities for each calibre type.

Written Handover Notes

Every service closes with a written note — what was done, what was found, and anything worth monitoring. Plain language, no abbreviations.

No Unannounced Costs

If anything unexpected comes up that would affect the final cost, we contact you before proceeding. Nothing is added without your knowledge.

Realistic Timelines Given at Intake

We provide an honest estimate at intake, not an optimistic one. If a job takes longer, we'll tell you as soon as that becomes clear.

Intake Photography

Photographs of each piece are taken at intake and kept on file until collection. Pre-existing marks and condition are documented from the start.
