Our methodology

Every service begins the same way.

01

Assessment

We open the case, examine the movement and seals, and form a view of what is needed. This is explained to you plainly before anything else is discussed.

02

Written Scope

If you choose to proceed, we set out the work to be done and its cost in writing. Nothing begins without your agreement to that document.

03

Careful Work

The work is carried out at the pace it requires. You are notified on completion and given a summary of what was done and any observations for future care.


Watch diagnostic and service

Service 01

Basic Diagnostic and Service

Helpful for owners who are unsure what their watch needs and would like an honest opinion first. The assessment is explained plainly, with no obligation to continue, and a service warranty applies to any work carried out.

Service 02

Water Resistance and Seal Service

A practical service for watches worn near water or simply in daily life, focused on restoring the seals that keep moisture and dust out. We replace gaskets, attend to the crown and case back, and test the watch's resistance where its design allows.

Recommended for dive-style and sports watches as well as everyday pieces. Any required parts and costs are confirmed before work begins, and honest advice is given on what level of water contact is sensible afterward.

What is included

  • Full gasket replacement (case back, crown, crystal where required)
  • Crown and tube inspection and service
  • Calibrated pressure testing where design permits
  • Written parts and cost confirmation in advance
