The New Witschi WisioScope S
By Aaron Recksiek, CW21
The WisioScope S represents a brand-new standard of precision watch timing in the watch industry’s after-sales service sector. The machine was announced in June at the Environnement Professionnel Horlogerie-Joaillerie (EPHJ), a show designed for brands to exhibit new tools and technologies in the watch industry.
At first glance, the machine resembles the Witschi S1 in size and appearance. The main noticeable differences are the full-color, 800 x 480-pixels display and the extra optical attachment mounted on top of the acoustic microphone. The camera mounted on top of the microphone is capable of visually recording the rate and amplitude independently, or in synchronicity, of the acoustic sound of the escapement. A non-harmful Class 1 laser is used to track the movement of the balance wheel, much like a modern hairspring vibrating tool.
The “real lift angle” of any watch can also be automatically calculated by comparing the optical readings with the acoustic sounds. The real lift angle of any watch might be slightly different than the manufacturer-specified theoretical angle, depending on the adjustments done to the escapement. This machine also allows the rate and amplitude of watches with special escapements to be recorded because the laser tracks the motion of the balance wheel. This is critical in modern industry because of advancements in silicon technology and other new, unconventional escapements being developed every year. The
machine is capable of recording the rates of a watch even in an extremely noisy environment, which is not possible with an acoustic-only machine. The interface is also capable of simultaneously showing the optical readings in comparison to the acoustic readings to help determine if there are any errors in the escapement.
The software for the new machine was developed in collaboration with the Centre Suisse d’Electronique et de Microtechnique (CSEM) in Neuchâtel, and funded in part by the Swiss Commission for Innovation and Technology (CTI). Witschi and CSEM jointly presented the new technology at the Congrès international de chronométrie 2016 (2016 International Chronometry Conference) in Montreux, Switzerland. Now that the innovations on this front have been made, it’s likely that we will soon see a new requirement of higher-precision machines in the modern watch-repair facility.
The WisioScope S will be available for purchase in the first quarter of 2017 and will be priced at 9,450 Swiss francs (approximately $9,651).
