Our Methodology

How We Handle Each Piece

Every watch arrives at the same starting point: an intake log. Before any service work begins, the piece is assessed, its condition noted in writing, and a service scope is confirmed with the owner. Nothing is done without that step.

Where parts need replacing, we work to source components appropriate to the movement — manufacturer-equivalent where original parts are unavailable, or period-correct sourcing for vintage calibres. We do not use generic substitutes when better options exist.

The pace of the work is set by the work itself, not by a target queue. Timing regulation is done on a calibrated machine, and each serviced movement is checked before and after casing to verify the result.

For archive-grade overhauls, a staged photographic file is assembled alongside the work and returned to the owner with the piece. The timeline for each service is communicated on intake, and updated if something unexpected is found.

Scope Agreed Before Work Begins

No work is carried out without the owner's agreement. If the assessment reveals additional needs, we contact you before proceeding.

TS-05

Appropriate Lubricants
