Rolex 3235

Disclaimer

An approximation of the Rolex 3235 layout from public drawings and photographs, not a manufacturer-accurate replica. Bidirectional winding by a monobloc rotor on a ball bearing held by a single screw, red reversing wheels, 28,800 vph (Rolex: eight beats a second), about 70 h power reserve, the Chronergy escapement (cut-out nickel-phosphorus escape wheel and fork, thinner pallet stones, offset pivots), the variable-inertia balance with four gold Microstella nuts, the blue Parachrom hairspring, the traversing height-adjustable bridge, Paraflex, the instantaneous date with rapid setting and stop-seconds are Rolex figures. Rolex publishes no jewel count, diameter or height: 31 jewels and Ø 28.50 mm come from Caliber Corner, Grail, Ranfft and Chronospex, and no reliable height was found. The orientation follows Rolex’s caseback render (balance at about 6, crown at 3: medium confidence). Tooth counts, wheel sizes, the barrel position, the train layout, the bridge outlines, the position of the escapement, the number and position of the reversing wheels, the seconds drive and the dial side are an approximation; the bridges are shown grained because no source names a decoration. Parts are drawn larger than life for legibility. The escapement motion is a kinematic model, not a physics simulation.
