Now that we know what the jewels are, you may be wondering why they’re even in place. Good question – they let your watch last longer.
You know that timepieces have gears in them. Like you would with a bicycle, you’d want to lubricate them. Watches are sealed, so this is tricky to do.
This is where jewels come into play. They keep friction at bay. They’re placed in-between gears to stop them from rubbing against each other. They are the reason why your watch hasn’t broken down yet.
You’re probably wondering - are more jewels in a watch better
? Yes, they make it run smoothly.
You won’t find an automatic watch without the glass pieces, even the cheaper ones. This is as they have a myriad of gears in them.
Mechanical watches usually come with 17 jewels. However, the best ones have more. Our personal favorite, the Seiko SRPD5 carries 24 in its gears. Swiss watches are the pinnacle of craftsmanship
, which is why they have the most jewels.
Not only do they let watches last longer, but jewels let them be more accurate
If you think about it, you can probably guess why:
Friction stops gears in their tracks. The more friction that builds up, the slower the gears would move. Over time, your piece would display time that is way behind. Jewels especially in a watch’s bearings prevent this from taking place.
