Set of 3 tachometers tachometers with original box, Smith England, Zivy and Hasler Swiss. Not complete (missing some tips on two boxes) and are not tested. Zivy & Cie, SA, Basel, Switzerland, original box and almost complete, missing one accessory, sold by a watch dealer in Prato, original instructions. High quality. Same for Hasler, Bern, Switzerland, the box seems complete, with its original instructions. Overall they are very nice, and can also be displayed.
