This is a pre-owned version of Rolex’s GMT-Master II (Ref. 16710).
With a black bezel and red 24-hour hand, it allows you to read a second time zone while simultaneously using the standard hour hand for local time.
Unlike all the GMT-Master II watches in the 2025 Rolex catalog, this model has a single-colored bezel insert, which does not distinguish between day and night at a glance, the way the two-tone bezel-equipped models can.
It’s more about form and less about function, which is why it’s easy to see why some people are drawn to this particular style.
