The caliber 27-460 is stamped with the Geneva Quality hallmark, and it has the Patek Philippe seal. It's rhodium plated, with fausses cotes embellishment, a shock absorber device, and a straight-line lever escapement. It includes a self-adjustable balance spring stud carrier, an adjustable-mass balance with a Breguet over coil spring and a Gyromax balance that's adjusted for heat, cold, isochronism, and 5 positions, and a centrally mounted solid 18K yellow gold rotor, consummately decorated with engine turning.
This mechanism oscillates at the frequency of 19,800 vph (3 Hz). 
The caliber 27-460 M, successor of the caliber 12-600 AT, was the first automatic watch movement with a date produced by Patek Philippe in a series in production for 25 years, from 1960 to 1985.
This caliber 27-460M offers the same exquisite finishing as the 12-600 AT movement in the ref. 2526.
Walt Odets called Cal. 27-460 "the reigning queen of that half century" and "the most elaborate and costly simple automatic watch movement ever produced."
Caliber 27-460 M was also called "La Grande Dame des automatiques Suisse"
