316L Stainless Steel
Definition
316L stainless steel is the alloy used for cases, bracelets and buckles in nearly all watchmaking. The L stands for low carbon; molybdenum gives it resistance to chlorine and sweat. It releases little nickel, which is why it is called «surgical». The buckles on my straps are made of stainless steel, the same type of steel as the case.
Frequently asked questions
What is 316L Stainless Steel?
The most widely used stainless steel in watchmaking: cases, bracelets, buckles. Low carbon, molybdenum against corrosion, low nickel release. It is the steel family of the buckles on my straps.
Why are Milano Straps buckles made of stainless steel?
Because it is the same type of steel as the case on nearly every watch: same tone, same resistance to sweat, little nickel in contact with the skin. A buckle in a different steel becomes noticeable after a year, when one of the two parts has yellowed and the other hasn't.
How do I match a strap to a 316L steel case?
I encounter 316L steel in the case and the buckle, not at the workbench: I work with leather. It is the most flexible pairing: it suits smooth calfskin, box calf, alligator, cordovan. The watch makes the choice: for a sports watch, grained leather or rubber; for a dress watch, box calf or alligator.
