Servicing and Restoration

Three jobs, three different aims

Servicing is planned maintenance: examining a watch, cleaning its mechanism, renewing lubrication where required and checking its operation. Repair addresses a fault, such as a damaged winding component or a failed seal. Restoration is a more interpretive undertaking, often involving an older watch whose worn, altered or missing elements require specialist decisions. The terms overlap, but they should never conceal the scope of the work.

A useful starting question is what the owner wants to preserve. A daily companion may need dependable operation and an agreed level of water resistance. A historically significant watch may call for greater restraint, with original surfaces and components taking priority over a factory-fresh appearance. Neither objective should be left implicit.

What happens during a full service

A mechanical overhaul generally begins with assessment and an estimate. The movement is removed and dismantled; components are inspected, cleaned and repaired or replaced as necessary. Reassembly includes carefully specified lubrication and adjustment. This is substantially different from regulating a watch, which adjusts how much time it gains or loses without necessarily addressing wear or contamination inside it.

Rolex's published procedure follows this sequence and separates movement work from case and bracelet work. It also includes renewed seals and pressure testing. Patek Philippe describes additional checks covering winding, power reserve, accuracy and simulated wear. These examples illustrate the breadth of a full service, rather than a checklist every workshop or watch must follow identically. A quartz battery replacement is likewise a particular intervention, not proof that every aspect of the watch has received an overhaul.

A calendar is a starting point

There is no universal service interval for wristwatches. The movement, lubricants, age, exposure and manufacturer's instructions all matter. Rolex currently recommends approximately ten years, depending on model and real-life use; Grand Seiko's instructions for its 9SA4 movement recommend an overhaul approximately every three to four years. Those recommendations belong to their respective watches and should not be transferred indiscriminately to others.

A marked change in performance, damaged controls or a significant impact merits assessment rather than waiting for a scheduled anniversary. Persistent condensation under the crystal is particularly important: Grand Seiko's care instructions advise immediate consultation. Water resistance also deserves its own conversation. Aging gaskets or damage can compromise a case even while its movement continues keeping time.

Originality is a set of decisions

Originality does not mean that every component must remain untouched forever. Replacing a worn working part can be essential to safe operation. Yet a new dial, handset or bezel can change a watch's appearance and remove evidence of its earlier life. A genuine manufacturer replacement is still a replacement; authenticity of the part and originality to that particular watch are separate questions.

Patek Philippe describes its restoration atelier's objective as retaining original movement and case components wherever possible, with specialist manufacture of unavailable parts when needed. The British Horological Institute's code similarly emphasizes respect for an object's original character. The practical lesson is to distinguish required functional work from optional cosmetic work before authorizing either. Ask what will change, why it is necessary, and how the intervention will be recorded.

Polishing changes more than shine

Cleaning removes dirt; abrasive refinishing removes material to alter the surface. Done sensitively, refinishing can restore the intended relationship between polished areas, brushed planes and crisp boundaries. Done aggressively or repeatedly, it can soften lug profiles, reduce bevels and weaken shallow markings. An article in the American Watchmakers-Clockmakers Institute's Horological Times stresses identifying original finishes and protecting corners from rounding during polishing.

Declining polishing can therefore be a deliberate conservation choice, while choosing expert refinishing can be reasonable for a modern watch whose owner prefers that appearance. Neither decision should be automatic. The material, coating, existing damage and remaining geometry limit what can responsibly be achieved. 'Light polish' is too vague on its own: specify the areas, intended finish and features that must remain intact.

Write a brief before the watch leaves

Record the reference and identifying numbers privately, photograph the condition, and describe symptoms and service history. Agree whether dial or hand replacement, reluming (renewing luminous material) and case refinishing require separate permission. Ask about parts availability, the estimate process, likely timescale, transport arrangements and the treatment of removed components. Ask explicitly whether replaced parts can be returned; their return should never be assumed.

Choose a provider with demonstrable experience of the relevant movement and case construction. A manufacturer's network may offer proprietary parts and factory procedures; a qualified independent specialist may suit a particular older mechanism or conservation brief. The decisive issue is capability matched to the watch and the agreed objective, including any applicable warranty conditions.

The record is part of the result

On collection, check the agreed functions and review the invoice, replaced components, test results and service warranty. Establish the watch's current water-use guidance rather than assuming an old dial inscription describes its present condition. Keep photographs and paperwork together. A well-documented intervention explains what survives, what changed and what the next watchmaker should know; it makes ongoing stewardship more informed.

Turn a service estimate into clear choices

Imagine an estimate listing a movement overhaul, a replacement handset and case refinishing. Those are three decisions, even when a provider offers them in one package. Ask which items address the reported fault, which are required by that provider’s service policy, and which change the appearance. If an intervention cannot be separated, understand that before authorising the work.

Write the objective in ordinary language: dependable daily use, conservation of a family object, or a particular cosmetic result. Then ask the provider to describe the proposed changes and any limits. “Please retain the current dial and hands where function permits, and contact me before any replacement” is clearer than “keep it original.” It is a question to agree with the workshop, not a promise that a particular part can safely remain.

Compare the result with the brief

Keep a dated copy of the agreed scope and the pre-service photographs. On return, compare the completed invoice with that scope: what was cleaned, repaired, replaced or refinished, what tests were performed, and what the service warranty covers. Ask about any difference in plain language. A record of the work is more useful than an unqualified statement that the watch is “as new.”

Treat water-use advice and cosmetic approval as separate conversations. A timing result cannot establish the current state of a case’s seals; an attractive finish cannot establish movement condition. Retain the service record privately with the watch’s instructions. This owner checklist develops the earlier guide’s questions; it is not a diagnosis, a legal service contract or a claim about the policies of every workshop.
