Swiss-Grade Automatic Clone of Caliber 3155
The Rolex Day-Date 118239-0304 super clone runs on a Swiss-grade automatic clone movement modeled on the genuine Rolex Caliber 3155 that powered the 118239 from production launch through 2018. The clone movement operates at 28,800 vibrations per hour (4 Hz), drives a quickset day display and quickset date display via the crown, and holds 50 hours of power reserve after a full wind. The movement carries factory regulation before shipping and remains protected by the closed white-gold-tone caseback.
Accuracy and Daily Performance
Daily deviation holds within -5 to +10 seconds per day after factory regulation on this Rolex Day-Date 118239-0304 super clone. The smooth sweep of the seconds hand confirms the 28,800 vph beat rate at a glance, separating this movement from quartz or low-grade automatic clones that tick or stutter. The quickset day and date crown function lets you advance both displays without rotating the hands through 24-hour cycles, which is the practical convenience the genuine 118239 buyers value most after wrist comfort.
