Moving beyond Sinn, for those that don't plan to do a lot of strap changes, the Oris Aquis comes in both 41.5 and 39.5mm sizing, and both offer a distinctive style. The 39.5mm size can link be had for $2,100 ($2,300 for the very pretty Clean Ocean LE), and they are 13mm thick and offer 300m water-resistance. It's a less techy option than the Sinn, but for that money, you get a bracelet and a ceramic bezel, which remains a solid value.
