State of the luxury watch industry is a bit of a mess. Watchmakers not really being progressive with marketing their products to a newer crowd. It'd be daring if any decided to offer a watch as a drop, but it'd be one hell of a way to get exposure and spread the word. That Sennheiser HD6XX drop was a hint of what kind of fuss could be drummed up.
I have the speedmaster pro and the Sinn 856 utc, and both are lovely watches. I prefer the Sinn, the speedy needs hand-wound, and in all the 15 years I have worn the speedy before I got the Sinn, only 1 person commented on the looks of the watch. Bang for buck the Sinn has the edge imo. I know the 3570 is the grail but trust me, the Sinn is a lot of watch for the money
