I think the 'Rising Sun' Speedmaster from 2018 is one of the sharpest versions out there, but I never cared for it on a bracelet. I once saw it on a Himalayan croc strap but that material is very hard to find. Finally got word from George at Genteel-Handmade that they had it back in stock. I think this is the most expensive strap I've ever owned, but it's a beautiful material. I use an Artem deployant buckle which I like better than the standard Omega DP.
