Phil....
This discussion about the clocks made me so curious that I wanted to understand more of my clock and generally about electric clocks and how they works and learned alot of things I ignored, thanks!
I spoke with my sister yesterday of it about the alarm clock, and she does remember that granma gave it to us to bring to Italy because she said it was not working for her and had a problem of electricity, I believe that she knew of it by an electrician I bet she did not even know what cycles were, not sure what was the exact origin of that clock , she probably bought it used.....
I did forget about this story, I just remember I liked it so much with all the lights etc and was so happy to have it and my mom had to buy a new bigger luggage to fit it into...
It does have an hidden switch to twist with a screwdriver stating 50 and 60 on the 2 sides under the rear panel on the right side....
I believe it's the cycle switch and now it is pointed on 50, label tell 115/100 volts 60 cycle (actually 60 cy) a corner is cut so maybe it stated 50 cycle also, of course it's so....
I think it does have a kinda brake or mechanism inside to make it work right with both cycles and speed also....just guessing, or a thing converting hertz, not sure if that is that simple though....you look more expert than me.....
I'm not into clocks as you can understand, my father is more being a jeweler, I gotta ask this to him....
The clock states:
Made in Hong Kong, no date available.
Warnings are printed in english and japanese/chinese, but who can tell exactly? LOL
I believe it is from late 70s from the style.....
I also googled the matter and looks common to find american people with clocks running slower in 50hz countries, so another thing confirming you were right!
I never noticed my appliances works slower though, elements does not in my experience and nor motors runs slower significantly.
My mixer mix as it should blender also, fryer and steam irons all works like a charm and lamps too, so anyway what you could meet with an electric stove is the problem of the clock only I believe...
Anyway I'm glad I learned a new thing thanks of you Phil, that is good to learn of it that a 60 cycle clock will not work with 50, and this is good for many reasons apart personal culture...and specifically because I was watching one of those VTG electric coffee makers with built in clocks to give to my sister for Christmas!
Thank you for making me realize that.
