OK, so maybe this is just a petulant dummy-spit, but I really have to say this:
The Di Grisogono Meccanica DG is NOT the 'world's first mechanical digital watch'!!
Digital watches have been around since the late 17th century and they've been in fashion several times every century since.
I have a Ruhla Digi 73 and a Nelson Digital, both jump-hour digitals from the 1970s, that I wear regularly, and I have an 1885 Gedeon Thommen jump-hour/jump-minute piece awaiting restoration.
What the heck is this if it isn't a mechanical digital watch, eh?
I'm sorry for the outburst, it's just that I'm getting really pissed off that when I google "mechanical-digital watch", I've got to trawl through pages of Di Grisogono pretentiousness before I get to the good stuff.
If you feel the same way, please post pictures here of your own mechanical digital watches.
