Rolex 3185 Description

The Rolex Caliber 3185 is a self-winding mechanical movement known for its robustness and reliability. It famously powered the Rolex GMT-Master II and Explorer II models. Its key feature is the independently adjustable 24-hour hand, allowing for the tracking of a second time zone. As a COSC-certified chronometer with a Breguet overcoil and KIF anti-shock system, the 3185 is a highly precise and durable “workhorse” movement that remains well-regarded by watch enthusiasts.
