I’ve always thought that the Air-King is a hugely under-rated watch. Its simplicity is a joy, and although the 34mm case is considered small these days it actually makes the watch incredibly versatile. Dress it up and it’s the perfect dress watch; dress it down and you can wear it with jeans or shorts.

With this in mind, when an example comes along that dates back to 1970 but looks like it left the Rolex factory only yesterday, the decision to buy is quite an easy one. You can see why from the photos, and now I’m searching for an authentic bracelet – possibly a rivet bracelet, in fact – to pair it with.
