This watch is a popular type called a "roulette" that has an engraving on the inner bezel of a later model, and is priced higher than watches without the "roulette".
Random product numbers for the final year of production of the Explorer I Ref. 114270 are particularly rare compared to other sports models, so I'm sure there are some people out there looking for them.

The classic model "Explorer I" Ref. 114270 with a 36mm case size is a perennial favorite.

It is the ultimate simple watch, with no date display, only black dials, and only stainless steel cases. Because of its simplicity, it blends in with any outfit, and many people rate it as "the most user-friendly Rolex model."
