This Zenith Sporto watch is dated to 1968. It has the in-house caliber 2542 movement (17 jewels), that beats at 21,600 bph. It is in superb condition, recently serviced – cleaned and oiled and the case and the back have been only slightly polished to keep the vintage taste and not overpolish. The diameter is without crown 33.4 mm and 39 mm lug to lug. It has the champaign white dial – awesome condition as well. The crown is generic, but a lot of those seems to be with one like it – no crowns with the Zenith logo from that period are to be found, so it might as well be the original one. It is fitted with a brand new Hirsch Buffalo strap (size M) with a Hirsch buckle that fits it nicely.
