The Zenith S.58 is a personal favorite of mine. It’s a gorgeous vintage diver that is generally overlooked nonetheless. As its name implies, it was originally launched in 1958, first with a hand-wound movement, and in 1960 and automatic caliber was added. Here we have the latter version. The S.58 was obviously built tough with practicality in mind, with a 37mm waterproof case, a rotating bakelite bezel, and lumed numerals on the dial. The deeply engraved case back is another attraction of this Zenith, clearly showing its reference number. In short, it is a very attractive package for a fraction of the price of a contemporary Rolex Submariner, which, at the time, did not even offer a date.
