I bought this a few months ago. Not at all happy. Stops working. The Dasate doesn't always change. The Middle screw pops out or something. Cannot read it at night. And forget about registering it. The numbers don't seem to coincide.
I'm disappointed with the tach in a whole. The hands blend in with the bezel, so it makes it extremely difficult to tell the time. I would not recommend this watch to anyone.
