Bucherer launched its own limited edition too only available in their store ASFAIK.
"Bucherer is one of the oldest names in watch retail. The shop's 130th birthday is fast approaching (2018), and to celebrate they've created a capsule collection of watches all focused around the color blue. The latest of the so-called Blue Editions is this partnership with Tudor, the Heritage Black Bay Bronze Blue. And it's exactly what it sounds like."
