The 1950 3 Days case adds a small-seconds sub-dial at 9 that PAM01523 does not have; do not confuse the two references.

Known issues in the market
  • PAM01312 and the plain Luminor Marina PAM01523 share the 44mm case and P.9010 caliber but differ in dial layout: PAM01312 has small seconds at 9 and date at 3, PAM01523 does not carry small seconds.
  • Cal. P.9010 is Panerai's top-tier automatic with a double-barrel 72h reserve; verify through caseback.
