Help needed re JB Champion or Forstner Komfit straps

Quick question for the vintage Speedmaster collectors. Do JB Champion and/or Forstner Komfit straps come in different widths? I know there are different end piece widths; i.e 19mm and 16mm but does the width of the strap itself vary on diferent models? To illustrate the pics below show a 16mm end piece with a 12mm strap width. Would a 19mm width end price example also have a 12mm strap? From casual observation I had the impression a 19mm end price bracelet had a 16mm wide strap but have never handeled one in person to know. Thanks in advance, Zac

I think all the ones used by NASA were 15.6 mm wide regardless of the end tube width. You might check MWO as they have chapter in the latest version.

You are completely right. Just checked my copy and page 208 say they are 15.6mm wide. Thanks.
