Professional Watch Testing with the Witschi WAIO at Crown Vintage Watches

At Crown Vintage Watches, we are always looking for ways to give you more confidence in the watches you buy from us. Our latest addition to the workshop is the Witschi WAIO, a state-of-the-art testing unit that elevates the way we assess mechanical and quartz watches before they ever reach your wrist.

Why Crown Vintage Uses the Witschi WAIO

As far as we are aware, ours is currently only one of a handful of  WAIO operating in Australia, bringing a level of watch-testing capability normally reserved for major service centres and brand facilities. The WAIO is a comprehensive, professional instrument designed to analyse chronometry, water-tightness, shock behaviour, magnetisation and accuracy in both mechanical and quartz watches.

This is not a typical timing machine. It is a fully automated diagnostic platform with a 7-inch touchscreen, precise acoustic sensors and data recording features that replicate what happens inside factory-level service environments.

Advanced Mechanical Watch Testing for Accuracy and Reliability

Multi-Position Timing for Real-World Performance

The WAIO listens to the heartbeat of a mechanical watch, analysing:

• Rate accuracy (–999 to +999 seconds/day, ±0.1 s/d)
• Amplitude (70° to 360°, ±1°)
• Beat error (0–9.9 ms, ±0.1 ms)
• Beat rate (3,600–72,000 A/h)
• Lift angle (manual, 10–90°)

Testing across four positions — dial up, dial down, crown up and crown down — simulates real wrist wear rather than flat-bench conditions. This reveals issues such as positional variance, unstable amplitude or early lubrication fatigue.

Quartz Movement Diagnostics

Quartz watches also receive full technical evaluation, including:

• High-precision rate measurement (0.01 s/d)
• Motor pulse detection
• Power level monitoring
• Inhibition and motor cycle evaluation

This is critical for verifying the long-term stability of quartz movements, particularly vintage high-accuracy calibres.

Assurance Through Technical Precision and Data Recording

Magnetisation Detection and Demagnetisation

Magnetisation is a common cause of erratic timekeeping. The WAIO performs:

• Controlled demagnetisation cycles
• Pre and post rate comparison
• Residual magnetism verification (<40 μT)

This ensures your watch leaves our workshop free from everyday magnetic interference.

Pressure and Leak Testing for Case Integrity

The WAIO includes a built-in air compressor to run dry pressure tests up to 5 bar, measuring case deformation with 0.01 micron resolution. Even for vintage pieces that aren’t intended for water use, verifying case tightness ensures protection against moisture, humidity and environmental changes.

Shock Detection for Vintage Watch Health

The WAIO monitors how a watch reacts to simulated real-world motion, highlighting whether past impacts have subtly affected rate stability or balance performance.

Data Storage and Traceability with Wicotrace 360°

Every test performed on your watch is:

• Stored automatically
• Linked to its serial
• Fully exportable
• Recoverable during future service conversations

This level of documentation gives long-term confidence and transparency. If a question arises years later about how a watch performed when it left our workshop, we have real measured data — not memory or guesswork.

Protecting the Watch During Testing

The WAIO uses ScratchProtect contact surfaces, ensuring no case or bracelet marks occur during testing. This is especially important for vintage Rolex, Omega, Heuer and other desirable steel sports models.

Bringing Laboratory-Grade Testing to Vintage Watch Buyers

Investing in the Witschi WAIO is part of our commitment to treating every watch as if it were our own. With:

• Multi-position chronometry analysis
• Quartz motor and rate diagnostics
• Pressure leak testing
• Magnetisation measurement and demagnetisation
• Shock response analysis
• Permanent digital records

We can offer genuine assurance that a watch has been tested, verified, documented and cleared as healthy before it reaches your wrist.

This is how Crown Vintage Watches raises the standard for vintage watch transparency in Australia — using the most advanced testing instrument available to give you complete confidence in what you buy.
