Rolex 10 1/2 Hunter

This refers to the size (10.5′′′) and architecture of a foundational family of manually wound Rolex movements. The Cal. 710 is a prime example, serving as a workhorse for men’s “Oyster” and “Precision” models in the mid-20th century. These movements were known for their reliability and robust construction, often featuring Rolex’s Superbalance, and were central to building the brand’s reputation for durable timepieces.
