What do you mean, a Spring Drive?
I actually preferred the music in the video to the actual watch.
I tried on a Speake-Marin watch a few years ago. The overall design is distinctive, I respect his work, and I was glad I got to try it on. However, that opportunity helped me to recognize its not for me. I struggle to decide if the overall design looks special, or if it merely looks like a concept from an amateur? Don't get me wrong, the workmanship is quite nice, but like others here the design just doesn't do it for me.
Titanium is lighter, generally more of a gray color that steel. Its also hypoallergenic (which works nicely for people who have allergies to metals with nickle content). I've never owned a titanium watch. I have heard that titanium resists scratching and denting better than steel, but that it is much easier to polish and remove scratches and small dents from steel.
Nice cars, but I like the old air cooled 911s more than current 911.
