Decent grade watches often have an overlapping circular decoration on the plates and bridges. Originally devised to catch dust, it’s now machine-applied for the most part and quite decorative. Here’s a picture from my C5 Malvern:

It’s called perlage, or more correctly L’oeil de perdrix (F.) literally translates in English as “partridge eye.”

Apparently, it has other applications too:

Yep, same pattern, applied to concrete in the parking garage. I’d guess it’s more for traction here.

There’s beauty everywhere.
