Hello,

A very well respected dealer is selling a 1985 Seadweller 16660 9.1XX Million Serial Number

I have a sensitivity to 904L so I need the older 304L case and bracelet.

What metal would this be and how do I tell without asking you experts with every watch I see.

Thanks in advance.

Joe

anyone?

Between 85-87 on the cases and much later for the bracelets. I'd say you are safe. Allergic to the Nickel?

Actually my allergy test came back this past week. i'm allergic to the copper. 2% in 904L

This makes sense. Even if the 904L has a higher Nickel content it actually sheds less nickel than 316L in a sweaty environment. I asked a researcher specializing in stainless steel interacting with body fluids and other corrosive environments.

I think tudor sub cases use the 316. Ever own one? I like them
More than my rolex models.
