Three levels of watchcare — precision instruments laid out

THREE LEVELS OF WATCHCARE

The Right Service
for Your Watch's Needs

Each of the three services at Nava Horology is designed around a different level of need. None is a package with unwanted additions — all work is discussed and agreed before it begins.

OUR METHODOLOGY

How the Work Is Done

Regardless of which service is appropriate, the underlying approach is the same: careful, informed, and communicated clearly throughout.

01

Intake & Photography

Every watch is photographed and logged on arrival. Case condition, dial state, crown, crystal — all noted before anything is opened.

02

Assessment Under Magnification

The movement is opened and examined fully under stereo magnification before any recommendation is made.

03

Written Report & Agreement

Findings and recommendations are put in writing. Work only proceeds once the owner has read and agreed to the scope.

04

Return with Documentation

On completion, the watch is returned with a full service record — what was found, what was done, timing results, water resistance result.

Opening inspection of a fine watch movement

SERVICE ONE

Opening Inspection & Maintenance

A gentle assessment for owners who wish to look after a fine watch with care. The watchmaker opens and inspects the movement under magnification, measures the rate, and reviews the seals, crown, and crystal. Where appropriate, the movement is cleaned and freshly lubricated. A written summary of condition and tactful recommendations follow, leaving any next steps entirely to you.

What is included

  • Full movement opening and inspection under magnification
  • Rate measurement in multiple positions
  • Seal, crown, and crystal review
  • Light cleaning and fresh lubrication where appropriate
  • Written condition summary provided

WORKSHOP STANDARDS

What Applies to Every Watch

Secure Handling

Every watch is individually labelled, logged, and kept in secure storage when not on the bench. The workshop is not left unattended during working hours.

Correct Tools Only

No improvisation with inappropriate instruments. All movement work uses watchmaking tools appropriate to the calibre in question.

Rate Verification at Completion

Timing machine results are recorded in multiple positions before any watch leaves the workshop. The owner receives these results.

Written Records

Every watch receives written documentation of its condition on arrival and the work completed. This record goes with the watch on return.

No Unauthorised Work

Nothing is carried out beyond the agreed scope. If something unexpected is found, the owner is contacted before any further work proceeds.

Originality by Default

For collectible watches, we do not alter the visual character of the piece without discussion. Patina, original finishes, and original parts are respected.
