In 1960 they cost $125.00 and they were guarantied a average daily accuracy within 2 seconds. Which at the time no balance wheel watch could even come close to that kind of accuracy, You just put a 1 dollar battery in it which would last a year, set the time once and enjoy accurate for a full year ! Quite a amazing feat of engineering for 1960 !

Here are some technical facts about the Accutron 214 movement....

The wire used in the coils is .015 (15 microns) thick

There are 8000 turns of wire used to make the coils

If unspooled the wire used is 90 meters long

The indexing wheel at the heart of the accutron is 2.4mm in dia

The indexing wheel is .04mm thick

The indexing wheel has 300 teeth

Each tooth is 1/100mm (10 microns) tall

The index and pawl jewels are perfect little square blocks of synthetic ruby, 0.18mm (0.007") square and 0.06mm (0.002) thick

In one year the indexing wheel turns 38 million times !

Is the Accutron still made and if not when was it discontinued ?

The real Accutron tuning fork watches were discontinued in 1977 Bulova kept using the name which I don't really like Because Accutron (accuracy through electronics) should have died with the tuning fork watches IMHO.....

OMG magnets, what now.
I think this has art project potential, but its also a few hundred worth of magnets.

Not sure it counts as a "video from YouTube you wish to share" if you upload it to your own YouTube channel just to post it here... Not really the point of the thread, but OK. :confused:

I'd like to share a little a bit about my work (clients) as of recent.
Doing some rebuilding of laptops and repairs for newcomers this week.

Food for thought. If you were a refugee fleeing your country and you had to restart your life,
what would you want? How would you adapt? Could you learn a completely new language and customs?
Would you keep some of your cultural identity? (probably, most likely yes)


This is humanity at work.




A little information about families from Syria coming to Canada.
(Not all is easy, many struggles to adapt)

Even if this type of music isn't your cup of tea anyone can recognize this one guy can play the guitar !




And this guy is the best drummer I've ever seen, It seems to come so effortlessly and natural !

Guitar shreds sound good, but mechanical music is the most stirring to me.
