Swiss-Grade Caliber 2236 Clone Movement
The Rolex Datejust 31 278274 super clone runs on a Swiss-grade automatic movement engineered to match the genuine Rolex Caliber 2236 in feel, frequency, and autonomy. The Caliber 2236 is the dedicated midsize movement Rolex built for the 31mm Datejust, fitted with the silicon Syloxi hairspring for resistance to temperature change and magnetic interference. The movement operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a power reserve of approximately 55 hours.
Accuracy and Daily Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 2236. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build, and the Syloxi hairspring helps the rate stay stable through daily wear. The 100-meter water resistance and the screw-down Twinlock crown let the Datejust 31 278274 super clone hold its seal through daily wear, hand washing, and light water contact.
