Variations on a theme.

I don't think mechanical watch making has 'moved on', just continually refined what was done centuries ago. There have been developments, but every hundred years or so.
Just making the case square or only having one hand doesn't seem very creative to me.

Motor cars are a similar. The endless creativity of modifying what has already been done.
A Veyron, advanced as it is, can directly trace it's lineage back to the cars trying to get from London to Brighton tomorrow. As with a Cortina, they're different, but essentially the same…….!!!
