The Sinn 144 is such a beautiful classic chronograph that screams 1970s, I'm surprised I don't see more around. Not too big at 41mm, but built like a tank with nice heft and wrist presence from a bead-blasted case. Not a glint or shine anywhere on it. And the way that red pops off of the deep black dial is fantastic. Great that Sinn still makes this iconic tool watch, although Watchbuys are sold out of them, and I rarely see them on the secondary market. Probably a good sign. That means guys hold onto them, like me.
