As a fun project some years ago,I set out to see if I could modify a mechanical watch run sdrawkcab! Here is the result. Runs fine, sdrawkcab! Wear two watches, and this one gives you 48-hours in a day! The job took me about two days to accomplish. When I first began to show it around, I had comments like,"Quartz movement that runs backwards?" Initially, I had to open the case to prove that it was mechanical. Eventually, I cut a hole in the case back and fitted a mineral crystal.
definitely cool, but there is an easier answer to the question of not having enough hours in the day... my solution has always been: just don't sleep.
