I have spotted them in some radio-alarm-clocks made in 1980's and walked away. Maybe next time I will grab one to have a look inside! No way to source locally a Numechron in Italy.<br /><br />The linked websites are very interesting! Thank you!<br /><br />73!<br />PaoloPaolohttps://www.blogger.com/profile/15102621371527878145noreply@blogger.comtag:blogger.com,1999:blog-5063268635618920899.post-12318414414060971472017-11-27T03:44:58.488+01:002017-11-27T03:44:58.488+01:00I remember the flip-clocks.

I like old-school tech myself. One thing that came to mind about the flip-clock was the Pennwood Numechron's of the 1930's are the oldest (to my knowledge) "digital" clocks made. I have many pieces of Heathkit equipment my father had that I now have. One piece, the SB-630 Station Console has a Pennwood clock in it. The digits are printed on faceted drums with an ingenious system of cams to roll the numbers over to the next value. If you like old clocks (Heathkit GC-1107 with VFD) then these old Pennwood's are a real treat to view.<br />http://www.uv201.com/Clock_Pages/pennwood.htm<br /><br />73!<br />Smitty<br />K4ACS<br />https://heathkit-interests.blogspot.com/<br />K4ACShttps://www.blogger.com/profile/15664263688383787516noreply@blogger.com
