The 6238 is a low-production manual chronograph whose value sits mostly in an unpolished case and an untouched dial, so most of the inspection is about originality rather than about whether the watch is genuine.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| case | Smooth polished bezel | A plain polished bezel with no tachymetre engraving, which is the defining feature of the last Rolex chronograph made this way | A bezel carrying a tachymetre scale, which belongs to the 6239 and later Cosmograph references |
| dial | Tachymetre scale printed on the dial | The tachymetre scale printed around the outer dial track, inside the bezel | No scale on the dial, or printing whose font and spacing do not match known examples of the same dial generation |
| movement | Valjoux-based caliber 72 | A 17-jewel column-wheel chronograph on the Valjoux 72 base, Rolex-signed and consistent with the case vintage | A cam-actuated chronograph movement, or any automatic caliber, neither of which belongs in a 6238 |
| case | Reference and serial between the lugs | Legible reference and serial numbers between the lugs, with sharp edges to the lug chamfers | Numbers worn shallow or gone entirely, which indicates heavy polishing |
| hands | Chronograph and subdial hands | A matched set whose lume, where present, has aged in step with the dial | Mismatched subdial hands, or a chronograph seconds hand in a finish that does not match the rest of the set |
