Watch Expert III
With the handy Watch Expert III (Watch Matic III) watch measuring and testing device, the measured values for rate variation, amplitude and beat error are automatically calculated and displayed numerically. The beat number of all current watch movements is detected automatically. For watches with a special escapement, the Watch Expert III tests and measures using appropriate measuring modes. The multifunctional Watch Expert III watch measuring device saves a measurement of five values on the screen which can be retrieved at a later stage.
