: It is very difficult to tell about the crystals
: from the photos (or any other photos). It
: might be worth asking the seller. Many
: collectors would consider a replacement of
: the crystals as an acceptable form of
: "routine maintenance" . . . same
: as with older chronographs.

: What appears to be white around the numerals is
: actually where the radium has receded /
: deteriorated over the years. In the more
: than 40 years since they were made, this
: seems to happen to all these radium-painted
: Master Times and Monte Carlos. In my
: opinion, another acceptable form of aging.

: To my eye, this is a great looking set that
: should fetch a handsome price. It's very
: difficult to find these older pairs that are
: real pairs, from the factory, and this one
: looks legitimate.
