Watch sellers often try to attract their customers with the supposed value of these pieces of jewels in the watch, but they are almost not valuable at all, at least not economically speaking. Today, they are not even natural gems, but artificially manufactured sapphire or ruby, called corundum.
Are jewels in watches worth money?
The higher the jewel count of your old watch, the higher it’s value. A 17 jewel watch is considered to be fully-jewelled. Historically, rubies were most commonly used as the functional jewels in antique watches due to the fact that they are hard and wear down slowly.
Are the rubies in watches real?
So yes, there are actually precious gems in the movement of your watch and usually quite a few of them! Back in the day, watchmakers used natural genuine rubies to create these bearings, and more recently, they adopted the use of lab-created rubies (also known as synthetic rubies) or sapphires.

Why do watchmakers use rubies?
