Rolex 6239 double Swiss underline – full spec

Collecting · · by Christian Bissener


Steel Rolex 6239 Cosmograph on a wrist, black dial with white sub-dials and Units per Hour tachymeter bezel

Finding a Rolex 6239 double Swiss underline in full spec today is something special. It is like finding an early Porsche 911 in a barn in superb condition.

This example was in sublime condition and had every detail a serious early Daytona needs:

  • 275 bezel
  • long hour hand
  • thin sub-seconds hand
  • double Swiss, underline dial
  • 6238 caseback
  • 6239 between the lugs
  • ROW import mark
  • the correct original US bracelet
  • a very early and correct serial, 92310X

We were sorry to see it go, but it found the right home with a fine gentleman collector who will take care of it and enjoy wearing it.
