Thanks Panerik, yes Noah/ Sohisticatedrogue strap is the one I've seen on instagram.
Glad that it will also darken and patina over time.
I'd preferably prefer OEM staps, yet I do know there are loads of aftermarket ones available.
Ideally I like something that I could wear for all activities and for it to last (guess how the above has been) I do like the OEM ranger that comes with the 372, but not so keen on the unburnished sides (which I doubt would work will swimming ect)
I'll let you know how the hunting goes.
