Watch repair tools on workbench

the work

Three services.
Each clearly defined.

A battery change, a full movement overhaul, or a patient end-to-end restoration of a piece with history behind it. Each service has a defined scope and a stated price.

methodology

How we approach each piece

Every watch that comes into Quartzen is handled the same way regardless of service level: it's examined, logged, and given a reference number. Nothing is started until the scope and price have been agreed. If the examination reveals anything that changes the expected cost, we stop and call you.

For mechanical work specifically, we don't skip the timing observation period. Assembling a movement and checking it once is not the same as observing it over several days across positions. The timing machine reading after assembly gives us a baseline; the readings taken over three to five days tell us whether that baseline holds.

Parts sourcing is handled by a dedicated member of the team. For standard services, parts are drawn from stock or ordered from verified Thai and Japanese suppliers. For vintage restoration, sourcing can take weeks and may involve contacting specialist dealers in multiple countries. We give an honest timeline when sourcing is involved and update you if it changes.

We keep records of all work. When you collect your watch, you receive a written condition report (for movement-level services) and, for restoration clients, a photographic log of the work carried out. These become part of the piece's service history.

shared standards

What applies to every service

Secure handling

All pieces are stored in a locked cabinet when not on the bench. A reference number is assigned at intake.

Written intake receipt

Every drop-off produces a written receipt with reference number and the agreed service scope.

Contact before additional work

Nothing is done beyond the agreed scope without prior approval. If something unexpected surfaces, we call you.

Correct lubricants for the application

Different movement parts require different lubricant viscosities. We use the correct type and quantity at each service point.

Privacy of personal information

Customer details are kept only for service administration purposes and are not shared with third parties. See our Privacy Policy for full details.

Follow-up if something is not right

If a watch returned from service develops an issue related to the work carried out, bring it back. We'll look at it without an additional service fee.
