Hi all, Just wondering if there's a definitive reference or resource for these bracelets. They have a strong relationship with Speedmasters obviously and was wondering if there's a discussion thread here for them? I'm new to the game and have lots of questions regarding them. I.E if in your opinion it is historically accurate to have one on a 145.022-69? I know it's more of a 105.012 and 145.012 kind of deal, but am aware 145.022s started to make their way through the cadre. Also, what's the deal with the flat type of bracelet. I do see them referred to as NASA JB Champion bracelets, but haven't seen photographic evidence of them being used. Photo for reference below.
