Cal. 3132 is a time-only automatic movement produced by Rolex since 2010. Like other movements of its era, it features a blue Parachrom hairspring and Paraflex shock absorber system. It is closely related to Cal. 3131, the anti-magnetic movement used in the Milgauss.

Cal. 3132 was the base on which Rolex built special movements for the Cellini line, Cal. 3165 and 3180. Both of these feature small seconds, at 3:00 and 6:00, respectively.
As oversized watches became popular in the 2010s, Rolex created a group of special oversized movements. Cal. 3132, 3136, 3156, and 3187 all have a 2.5 mm wider main plate, bringing the movement dimension to 30.97 mm. This is not well-documented, and many sources list these movements at the Rolex standard diameter of 28.50 mm. The difference is obvious at a glance, however, with the wider flange visible in Rolex promotional shots and in the watches themselves. This larger size allowed the date wheel to be enlarged, moving the date display 1 mm further from the center on the large Datejust II and similar models.
