Rolex Caliber 3132

The Rolex Caliber 3132 is a self-winding mechanical movement introduced in the late 2000s as part of Rolex’s next-generation lineup of time-only calibers. It is built on the brand’s proven 31xx architecture but incorporates upgraded materials and enhanced shock-resistance to deliver long-term stability and consistent precision. The 3132 is most commonly known for powering the Explorer 39mm and select Oyster Perpetual models, where reliability and understated performance are essential. Show more

The movement operates at 28,800 vibrations per hour (4 Hz) and features a 48-hour power reserve, offering dependable autonomy for everyday wear. Rolex equips the 3132 with its blue Parachrom hairspring—a paramagnetic alloy engineered to withstand temperature variations and magnetic interference. It also includes Paraflex shock absorbers, a major improvement over earlier generations, providing better resilience against impacts. The 3132 features a free-sprung balance with Microstella regulation, ensuring consistent accuracy even under challenging conditions. A bidirectional Perpetual rotor maintains efficient automatic winding, allowing the movement to stay powered with normal wrist motion. As a COSC-certified chronometer, the 3132 is tested and certified for precision before being cased and further regulated by Rolex.
