This is a reference I don’t often think of, but wow what a gorgeous watch!!
I think it looks great on every strap you put it on, with my favorites being photo #2 and photo #4
#4 appears to my eyes as a leather nato.. at first glance I thought it was an orange fabric nato and I think it you can find that burnt orange color in some kind of textile or fabric, instead of the leather, that would be my favorite.
I’m not a big fan of natos on my wrist. They look great for photos and the idea of them sounds comfortable, but everytime I decide to try one, I end up removing it pretty quick. Just too much fabric and height added for my taste. But I’m pairing it with a seamaster 300M, which is already not the slimmest case
Great photos of a beautiful watch, the rail master deserves more of my attention, what a great choice for a casual every day watch.
