How a Mechanical Watch Actually Works

Rolex · Mar 5, 2026 Technology

A mechanical watch stores energy in a coiled mainspring, releases it through an escapement controlled by a pallet fork, and regulates timing via a balance wheel and hairspring oscillating 3–6 times per second. Every tick you hear is the pallet fork releasing one beat of the gear train. The whole system depends on the physical properties of metals — elasticity, inertia, tensile strength — keeping time within 2 seconds per day.

André Heiniger, Rolex's second CEO, recognizes that technical product differentiation is no longer defensible — every Swiss company can now make a comparable watch. The answer is lifestyle. Between 1953 and 1963, Rolex launches an iconic suite: the Explorer (proto-worn by Sir Edmund Hillary on Everest in 1953), the Submariner (associated with Jacques Cousteau's Oscar-winning The Silent World documentary and worn by Sean Connery as James Bond from 1962–1995), the GMT-Master (developed in partnership with Pan Am to show two time zones for transatlantic jet pilots, featuring the iconic 'Pepsi' bicolor bezel), the Milgauss (magnetic-field resistant, co-designed with CERN engineers), and in 1963, the Daytona chronograph (named for Daytona International Speedway). Each watch is more than a product — it's a lifestyle category with a specific aspirational human context.
