Nice! Can they be found locally so did you have to buy online somewhere?
Can only get from Holben's, don't think I have ever seen them locally.
Anyways, I have a 20mm green and grey in this style (Palma Pacific - i.e. thickest weave in 2 piece style - note that one piece straps can scratch your caseback significantly if dirt gets trapped between, hence this choice ) to let go, you can find the green on Carousell (lazy to post the grey, maybe when I am bored during Christmas). Can ping me there if you're interested. Thought I might as well give a try since I have to be dinged on shipping, but those colors don't go with anything I have.
[Update] both straps have been sold
