  • The case measures 40 mm and the metal is Oystersteel (stainless steel) — weight and colour should match.
  • The bezel is: Steel tachymeter.
  • If the case is opened by a watchmaker, the movement is calibre 4030.
  • The serial should date to roughly 1988–2000. Check it with our serial-number decoder.
  • This reference has no date window — a 16520 with a date or cyclops lens is not genuine.
