What We Offer

Three Levels of
Considered Care

Each service is shaped by what your watch actually needs — not by a fixed menu. We begin with a conversation, proceed with care, and document everything throughout.

Our Methodology

How We Approach Every Service

01

Receive & Log

Your watch is checked in, photographed, and its condition noted before it is placed in secure storage.

02

Assess & Report

A thorough examination produces a written assessment with findings and recommendations — shared before any further work.

03

Work & Verify

Agreed service is carried out with the correct tools and materials. Results are verified against timing and water resistance standards.

04

Document & Return

Service documentation is prepared and your watch returned in appropriate packaging — ready to be worn and enjoyed.

Our Standards

Protocols Applied Across All Services

Secure Storage

Each watch is secured from the moment of receipt until return. Condition is photographed at intake and again before dispatch.

Correct Lubricants

Movement-specific Swiss lubricants are used throughout. No generic substitutions — each calibre's requirements are followed.

Timed & Verified

All regulated movements are verified on a certified timing machine across six positions before case reassembly.

Water Resistance Checked

Where water resistance is applicable, it is tested with calibrated pressure equipment after every case closure.

Owner Consulted First

No work that changes the character or appearance of a watch is carried out without the owner's specific agreement in advance.

Full Documentation

Every service produces written records. For restoration work, comprehensive documentation accompanies the returned watch.

Pricing

Transparent Starting Prices
