Rolex Movement & Calibers
A Rolex movement, or any other watch movement, is the heart of the watch. It's the mechanism that moves the hands and powers any complications, such as a chronograph, annual calendar or a dual time zone. The specific parts of a Rolex movement can vary depending on the model and the complications, but the basic components are similar across most mechanical watches.
Rolex Movement PartsHere are some of the key parts:
Main Spring: This stores the energy that powers the watch. When fully wound, the spring slowly uncoils and releases energy to drive the movement.
Gear Train: This is a series of interconnected gears that transfer the energy from the mainspring to the escapement. The gears also control the rotation of the hour, minute, and second hands.
Escapement: The escapement takes the energy from the gear train and releases it in controlled, regular amounts. This is what makes the "ticking" sound in a mechanical watch.
Balance Wheel: This part swings back and forth at a constant rate, usually 28,800 times an hour in Rolex watches, to control the rate at which the escapement releases energy.
Jewels: These are synthetic rubies used as bearings to reduce friction and wear on the moving parts. Rolex movements typically contain between 31 and 39 jewels.
Oscillator: It includes the balance wheel and the hairspring, which are responsible for the precision of the watch.
Automatic Winding Mechanism: In automatic watches like many Rolex models, this mechanism uses the movement of the wearer's wrist to wind the mainspring.
Rotor: Part of the automatic winding mechanism, it is a semi-circular weight that swings around with the movement of the wearer's wrist, winding the mainspring.
Pallet Fork: The component of the watch that interacts with the escapement wheel to create the ticking motion.
Dial Train: The system of gears that takes the motion from the escapement and translates it to the watch hands.
These are just the main components used in a Rolex movement. A mechanical watch movement can contain hundreds of parts, all working together to keep time. Rolex is known for its precision and quality, and each movement is a testament to the craftsmanship that goes into each watch.
Rolex Movements:1570 Movement: Rolex's own in-house movement, the 1500 series, developed in 19571.
3035 Movement: The first men's high-beat caliber Rolex made, featuring a quickset function.
3135 Movement: Forms the basis of most modern Rolex movements, includes an instantaneous date change at midnight. Variations include 3155 (day-date complication), 3130 (no date), 3131 (no date, with anti-magnetic shield), 3132 (no date, with Paraflex anti-shock system), 2235 (smaller with date, 2236 gets an updated hairspring), and 2230 (smaller without date).
3255 Movement: Introduced in 2015, doubles the accuracy of +6/-4 secs/day set out by Switzerland's official accuracy testing program, COSC1.
3186 Movement: 24-hour GMT movement, the 3187 picks up the Paraflex anti-shock system
9001 Movement: Most complicated Rolex movement with two time zones and an annual calendar (Sky-Dweller only)
4130 Movement: No-date chronograph movement (Daytona only)
Caliber 620: First automatic rotor that could wind the movement in both directions, introduced in 1930.
Caliber 1030: Known for its functionality and reliability, debuted in 1950.
Caliber 1040: Debuted in 1954, used in the Rolex Tru-Beat.
Calibers 1036 and 1565: Used in GMT watches for dual time zone display.
Caliber 1600: Introduced in 1964, used in the Rolex Cellini.
Caliber 1575: Introduced in 1965, known for its resilience and precision, used in the Rolex Datejust series among others.
Caliber 3055: Introduced in 1977, debuted the "quickset" feature in the Day-Date.
Caliber 3135: Introduced in 1988, one of Rolex's most famous movements, used in Datejust, Submariner Date, Yacht-Master, and the Sea-Dweller 4000, among others.
Calibers 3155 and 3185: Introduced in 1988, the 3155 introduced the "double quickset" feature in the Day-Date, while 3185 powers the GMT-Master II and Explorer II.
Caliber 2235: Introduced in 1999, mainly used in ladies' watches like the Lady Datejust and Lady Yacht-Master.
Caliber 4130: Introduced in the early 2000s, equipped with an innovative vertical clutch.
Caliber 9001: Introduced in 2012, the most complex Rolex caliber to date.
Calibre 3230: The Calibre 3230 is a self-winding mechanical movement entirely developed and manufactured by Rolex. It was introduced in 2020. This movement incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. The Calibre 3230 is equipped with a self-winding module via a Perpetual rotor, offering a power reserve of approximately 70 hours
