Three Services,
Each Described from the Component
Timing regulation, crystal replacement, and comprehensive servicing for late-model mechanicals. Each begins with a description of the part most relevant to the work.
← Back to HomeHow Intake Works
Every job begins at intake. The watch is examined visually, its condition noted in writing, and the appropriate service confirmed. If what we find during examination changes the scope of work, we stop and contact you before continuing.
Service delivery follows the same sequence each time: intake note, bench work according to specification, quality verification (timing measurement or pressure check), and written report to the customer. The sequence does not vary. A watch does not leave the bench without the verification step completed and documented.
Turnaround depends on the service: timing adjustment typically runs three to five working days; crystal replacement two to four; comprehensive service two to three weeks. These are working estimates. We will give you a specific timeline at intake based on current bench load.
Timing Adjustment & Regulation
The pallet fork and escape wheel together control the rate at which the hands advance. The escapementaad wheel's teeth are released one at a time by the pallet fork, which is itself pushed back and forth by the balance wheel. When the balance's oscillation rate has drifted — through temperature change, positional wear, or the passage of time — the watch loses or gains time relative to its designed specification.
This service addresses that drift. A short bench session with the Witschi timegrapher measures the rate in five positions, a light regulation of the regulator lever brings the rate within tolerance, and a follow-up timing pass confirms the adjustment has held. The service is appropriate for watches that have been on the bench within the last three years and whose movements are otherwise sound.
- Timing measurement in five positions on Witschi machine
- Light regulation of regulator lever
- Follow-up timing pass post-adjustment
- One-page timing record (before and after) issued to customer
Sapphire Crystal Replacement
The watch crystal is a transparent cover that protects the dial and hands while remaining readable. In modern watches, this is almost always synthetic sapphire — rated 9 on the Mohs scale, hard enough to resist most day-to-day contact, but not unbreakable. A deep scratch, a crack from impact, or a crystal that has been chemically marked all change how a watch looks and can affect the seal that keeps moisture out of the case.
We source a replacement crystal appropriate to the original case profile, fit it with the correct gasket and tension ring, clean the case exterior during fitment, and run a static pressure check once the case is closed. The customer receives a short note describing the replacement specification and the pressure check result.
- Replacement sapphire crystal, correct gasket and tension ring
- Case-side cleaning during fitment
- Static water-resistance check on reassembled case
- Written note: replacement specification and pressure check result
Comprehensive Service — Late-Model Mechanicals
A mechanical movement is not maintenance-free. The mainspring, gear train, and escapementaad all operate with metal moving against metal. Lubricants reduce wear at these contact surfaces, but they break down over time — thickening, migrating, or drying out depending on the surface and conditions. A movement that has not been serviced in four to seven years typically needs a full strip-down to restore the lubricant film correctly.
This service covers the complete process: written intake, full disassembly, ultrasonic cleaning of all components, lubrication at the correct friction points per manufacturer specification, replacement of common wear items, regulation in five positions on the Witschi machine, and a static pressure check. The customer receives a long-form report covering timing rates, amplitude, and beat-error figures.
- Written intake note and full movement disassembly
- Ultrasonic cleaning of all components
- Lubrication per manufacturer spec — friction surface by friction surface
- Replacement of common wear items as needed
- Regulation in five positions, Witschi machine
- Static pressure check on reassembled case
- Long-form service report: timing rates, amplitude, beat error

Shared Across All Services
Written Intake, Every Time
No bench work begins without a written condition note. The customer's description of the problem is noted alongside what we observe visually.
Contact Before Extra Work
If a job reveals damage beyond the agreed scope, work stops and we call or message you. Nothing additional is done without your explicit agreement.
Data Privacy
Customer contact details and service records are held only for operational purposes. We do not share information with third parties outside the service relationship.
