226570 Polar White & Black Dial — Clone Cal.3285 Fixed 24-Hour Bezel Guide
The Rolex Explorer II super clone collection — engineered in the 42mm case diameter and powered by the clone Cal. 3285. Distinct from the GMT-Master II, the Explorer II features a fixed 24-hour engraved steel bezel — not a rotating ceramic insert — and a dial designed for speleologists and polar explorers where the 24-hour scale eliminates ambiguity between day and night underground. The orange 24-hour GMT hand tracks home time against the fixed bezel, while the local hour hand adjusts independently via the crown.
Our super clones are forged from 904L Oystersteel with a fully brushed Oyster bracelet — no polished centre links — maintaining the utilitarian tool-watch character of the Explorer II line.

Collector Notes on Explorer II Super Clone Quality
The three primary inspection criteria on an Explorer II super clone are the fixed bezel engraving, white dial tone on Polar variants, and hand stack geometry.
The fixed 24-hour bezel carries a radial sunburst brushing across its face, with hour numerals recessed and filled with black enamel compound. The fill must sit flush with the bezel surface — proud or recessed enamel is the most common bezel defect on Explorer II replicas. On the Polar dial, the white lacquer must read as a cool, neutral white — not warm or ivory, which is the most frequently cited colour defect on lower-grade white dial Explorer II replicas.
The Cal. 3285 Caliber uses a Chromalight display: the hour markers and hands fill with a blue-emitting compound, not the green of earlier calibers. This detail distinguishes a correctly spec’d super clone from one built on an older movement base.
Clone Cal. 3285 — Independent Hour Adjustment
Pulling the crown to the first position advances or retreats the local hour hand in one-hour increments, simultaneously driving the date wheel, without stopping the running seconds or altering the 24-hour GMT hand position. This mechanical behaviour is verified across a full 12-hour forward and reverse cycle as part of our pre-shipment quality control process.
