Why Authorised Servicing Is Non-Negotiable
A Swiss mechanical movement contains hundreds of micro-engineered components, each held to tolerances measured in microns. When a TAG Heuer, Zenith, or Bvlgari timepiece leaves the Maison's manufacture, it carries a warranty built on one assumption: that any future intervention will use original factory parts and certified technique.
Third-party workshops, however skilled, cannot fulfil that assumption. They lack access to proprietary components, calibration equipment, and Maison-specific technical documentation. The moment a non-authorised hand opens the case, the manufacturer's warranty is voided, and the timepiece's provenance, so critical to resale value, is compromised.
Picot & Moss is the only company in South Africa authorised to service and repair the Swiss watch brands it represents, including TAG Heuer, Bvlgari, Zenith, Frederique Constant, Victorinox, and Hermès. That exclusivity is not a marketing claim, it is a certification issued by the Maisons themselves.
The Real Cost of Third-Party Risk
Many collectors in Johannesburg, Cape Town, and Durban are drawn to independent watchmakers by shorter turnaround times or lower quoted prices. The short-term saving, however, frequently produces long-term expense.
Consider the following risks:
- Counterfeit or incompatible parts: Non-OEM components alter timekeeping accuracy and can accelerate movement wear.
- Voided manufacturer warranty: A single unauthorised service eliminates coverage for all subsequent defects, regardless of their cause.
- Reduced resale value: Auction houses and secondary-market buyers in Southern Africa scrutinise service history. An unauthorised stamp reduces hammer price.
- Undetected complications: Certified technicians follow Maison-prescribed inspection protocols. Independent workshops may miss hairspring fatigue, gasket deterioration, or lubrication degradation.
The authorised service record, by contrast, is a document of provenance, as significant to a serious collector as the original certificate of authenticity.
Service Intervals by Movement Type
Swiss watchmakers publish recommended service intervals based on movement architecture. These are not arbitrary, they reflect the lubrication lifespan of specific oils, the wear rate of particular alloys, and the tolerance drift of escapement geometry over time.
| Movement Type | Recommended Service Interval | Typical Scope |
|---|---|---|
| Mechanical (manual-wind) | Every 3-5 years | Full strip, clean, re-oil, regulate |
| Mechanical (automatic) | Every 4-6 years | Full strip, clean, re-oil, regulate, rotor inspection |
| Quartz (battery-powered) | Every 2-3 years | Battery replacement, seal inspection, timing check |
| Chronograph (mechanical) | Every 3-5 years | Full strip, column wheel/cam inspection, re-oil |
| Tourbillon / Grand Complication | Every 3-5 years | Maison-prescribed protocol, specialist technician only |
Intervals are guidelines. Watches worn daily, exposed to salt water, or subject to magnetic fields may require earlier attention.
If you are unsure of your timepiece's last service date, the team at Picot & Moss's authorised service centre can assess its condition and advise on the appropriate course of action.
Step-by-Step: The Picot & Moss Authorised Overhaul Process
Understanding what happens to your watch during an authorised service removes uncertainty and reinforces confidence in the result. Below is the standard overhaul sequence followed at the Picot & Moss service centre in Sandton, Johannesburg.
Step 1: Initial Assessment
A certified horologist conducts a visual and functional inspection. The movement's amplitude, beat rate, and power reserve are measured electronically. Any external damage, case wear, crystal chips, crown resistance, is documented.
Step 2: Client Quotation & Approval
A detailed service estimate is presented before any work begins. No intervention proceeds without written client authorisation. This transparency is a cornerstone of the Picot & Moss service philosophy.
Step 3: Case & Bracelet Restoration
The case, lugs, and bracelet are separated from the movement. Surfaces are refinished to factory specification, brushed zones remain brushed, polished zones are re-polished, using Maison-approved techniques.
Step 4: Movement Disassembly
Every component is removed under controlled conditions. Springs, jewels, wheels, and the escapement are catalogued individually. Worn or fatigued parts are identified for replacement with genuine Swiss factory components.
Step 5: Ultrasonic Cleaning
All metal parts undergo ultrasonic cleaning in a sequence of specialist solutions. This removes decades of dried lubricant, debris, and oxidation without abrasion.
Step 6: Reassembly & Lubrication
The movement is rebuilt to Maison specification. Each pivot point, gear train interface, and escapement surface receives the precise grade and volume of lubricant prescribed by the manufacturer, a process requiring both specialist knowledge and certified oils.
Step 7: Timing & Regulation
The reassembled movement is tested on a timing machine across multiple positions. Accuracy is adjusted to meet, or exceed, the original Maison specification.
Step 8: Water-Resistance Testing
The sealed case undergoes pressure testing to verify gasket integrity. This step is mandatory for any watch carrying a water-resistance rating and is frequently omitted by non-authorised workshops.
Step 9: Final Quality Control
A senior technician conducts a 24-hour power-reserve run and final accuracy check before the watch is returned. The service is recorded, and a new warranty document is issued.
Step 10: Repair Tracking & Client Communication
Throughout the process, clients receive updates at each stage. Picot & Moss's repair tracking system provides visibility from drop-off to collection, a standard that distinguishes authorised care from the opacity of third-party repair.
Authorised vs. Third-Party Servicing: A Direct Comparison
| Criterion | Picot & Moss Authorised Service | Third-Party Workshop |
|---|---|---|
| Genuine factory parts | Yes, sourced directly from Maison | Not guaranteed |
| Warranty preservation | Yes | No |
| Maison-certified technicians | Yes | Rarely |
| Repair tracking | Full step-by-step visibility | Typically none |
| Water-resistance testing | Standard protocol | Often omitted |
| Service documentation | Official Maison record | Informal or absent |
| Resale value impact | Positive | Neutral to negative |
Caring for Your Watch Between Services
Authorised servicing is the foundation of long-term care, but daily habits extend the interval between overhauls.
- Avoid magnetic fields: Speakers, tablets, and bag clasps can magnetise a movement, causing timekeeping to accelerate by minutes per day.
- Rinse after salt water exposure: Even water-resistant watches benefit from a fresh-water rinse after ocean swimming.
- Wind manually-wound watches at the same time each day: Consistent winding reduces stress on the mainspring.
- Store in a watch box or winder: Automatic watches left unworn for extended periods should be placed on a quality winder to maintain lubrication distribution.
- Never adjust the date between 9 PM and 2 AM: During this window, many mechanical movements are mid-cycle on the date-change mechanism; forcing the corrector risks damaging the date wheel.
These habits, combined with scheduled authorised servicing, protect both the mechanical integrity and the investment value of any luxury timepiece.
