Rubber straps in the aesthetic known from Flieger watches.
Made of matte, quite soft rubber, with embossing on the inside to improve wearing comfort.
What watches do I wear it with? It works best on watches with a larger wrist presence and thickness over 12mm. It's a "piece of a strap" that could simply overwhelm a smaller, thinner watch. Its matte aesthetic also works better with brushed cases, but I've also seen it on a mirror-polished Breitling and it still looked fine. The top side is quite subdued, so it can be easily combined with both simple timepieces and watches overloaded with details.
