Sinn 256: Just picked this one up. Love it. I've always wanted a 156 or 256 because they are a great nod to the Sinn heritage. The 256 was my option as the 156's are a bit unobtainium these days. I also love the font on these dials, the curved '4' is just cool.
Sinn 403/EZM 2 GSG 9: This one kind of goes without saying. It's a Hydro, it's cool, and is everything a tactical/tool/dive watch can be. Great watch!
