Industrial equipment - Switzerland - Mechanical tachometer with stopwatch, produced by Hasler S.A. in Bern, Switzerland

Mechanical tachometer clock, produced by Hasler S.A. in Bern, Switzerland, presumably in the 1940s–1950s. In my opinion the condition is excellent, but I defer to a careful examination of the published photos since this is a sale on a 'sold as seen' basis. Complimentary compass box as shown in the photo.
