Rolex President

[gkenny]

Hi, I am new to this forum and this is my first post. I have a relative who owns a Rolex President about 45 years old. The stem does not wind the watch, it just spins. Everything else works normally and you can wind the watch by just turning it in your hand or on your wrist to wind it.

What are the possible problems? Is it something that can be repaired without sending to Rolex? What could be the possible to repair the winding this watch?

Thank you for any assistance that you can offer, it will be greatly appreciated!

Thank you very much, stay safe my friend, regards, gkenny.
