While any Submariner 5513 is usually worth a few thousand pounds, one like this on our hirsute MD’s wrist a few years ago can be worth over ten times as much. The “Explorer-dial” Submariners are those made with the unusual “3 – 6 – 9” dial format similar to those more commonly seen on plain Explorer models. Earlier Submariners than this could be found with them, but 5512 and 5513 variants from the early 1960s era are especially favoured by many. There were in fact several versions of the Explorer dial during the short period of production and this one, with its uncalibrated depth rating, has become widely recognised only in the last few years. This particular watch was subsequently sold at auction.
