What are Jewel Bearings

Post by koimaster » July 10th 2020, 10:28pm

“I’ve heard that there are some rubies on your watch? Must very precious, right? Wait, where are they? I can’t see them.” And when looking at a movement for the first time, people often ask what are the little red dots on their watch’s movement or why watches all mention the number of jewels? If you’re a watch collector, this conversation should be familiar. After looking at the evolution of the critical part that is the escapement, A Technical Perspective will today focus on an often underestimated part of a watch, even if its role is vital to a flawless run: jewel bearings.

With the lilt of Irish laughter

Every day and in every way

Now forever and ever after."
