316L vs. 304 Stainless Steel: Why the Grade of Your Watch Strap Hardware Matters

Most brands use 304-grade steel for their clasps, buckles, and spring bars, then charge you 316L prices. The difference shows up months later, when the joints start spotting and the hardware starts to pit.

"Stainless Steel" Is a Lie. Here's What Actually Matters.

"Stainless steel" means nothing on its own. There are dozens of grades. Some rust. Some corrode. Some turn your wrist green after a few months of sweat. The grade is everything, and most brands never tell you.

We use 316L. Here's why it's the only choice we'd stand behind.
