The standard configuration is a rotating engraved bidirectional bezel, predominantly Euro/ROW market: black aluminium insert, red triangle at 12, bidirectional rotation, single-unit 1-5 markings inside six 10-minute sectors. The 1-2-3-4-5 reading omits the trailing zero on each ten-minute mark; the bezel reads as 60 minutes divided into six sectors with single-unit refinement. Rolex’s reason for using the 1–5 layout is not documented. PerezCope's authentication test 5: serifed numerals are factory original; non-serif numerals indicate service or aftermarket bezel insert.
