This is a 1958-59 GMT Master 6542. I believe this was one of the last Guardless GMT Masters produced. The dots on the dial are relatively small and easily damaged, and in my experience, I believe this is the last 6542 dial.
As you can see from the image, the engraving on the back cover indicates that it is the third series from 1958, so we can assume that it is almost the final model.

The bezel was replaced later, so the base is stainless steel (not plated brass). The case is in very good condition and has retained its original shape. The movement is also original, with a butterfly rotor, allowing you to enjoy the movement of the hands unique to low beats.

This watch has previously been overhauled at an authorized Rolex dealer in Japan, so you can use it with confidence.

The bracelet is a Jubilee from the 1970s. The bezel has been replaced, so we have set the price quite low. The overall balance is very good, so in a sense it is a high-value piece.
It would be nice to find an original Bakelite bezel and attach it, or you could completely change the look with an Oyster triple rivet.

Please take this opportunity to consider it.
