Swiss-Grade Clone of the Rolex Caliber 3255
The Day-Date 228345RBR super clone runs on a Swiss-grade automatic movement engineered to match the genuine Caliber 3255's feel, frequency, and 70-hour autonomy. The movement operates at 28,800 vibrations per hour, drives the central hours, minutes, and sweep seconds, and powers the day display at 12 and the date at 3 through the same instantaneous jump architecture the original uses on the 228345RBR.
Accuracy and Finishing
Daily deviation holds within -2 to +4 seconds per day after factory regulation, tracking close to the Rolex Superlative Chronometer -2/+2 standard. The movement carries circular graining on the mainplate, polished bevels on the bridges, and a satin finish on the perpetual rotor. The bidirectional winding rotor delivers steady reserve build-up during normal wrist motion, keeping the Day-Date 228345RBR chronometric performance stable across daily wear cycles.
