Why Automatic 21 Jewels Is Necessary
From my experience, an automatic watch with 21 jewels offers a perfect blend of durability and precision.

This means my watch runs smoother and lasts longer without wearing down, which is essential for everyday reliability.
I’ve also noticed that the 21 jewels help maintain accurate timekeeping. Since these synthetic rubies minimize metal-on-metal contact, the movement stays more stable and consistent. For me, that means less frequent adjustments and a watch that I can truly depend on.
Ultimately, choosing an automatic watch with 21 jewels feels like investing in quality craftsmanship. It’s reassuring to know that my watch is built to perform efficiently over time, all while maintaining the charm of traditional mechanical engineering.
