My ex told me about this back in the early 90s. I was talking to two self proclaimed watch experts. They didn’t believe me, and tried to convince me that the quartz was actually the glass protecting the watch making me look and feel like a jackass. Than you for validating what I knew all along.

James was busy and couldn't film this video so they used an actor and motion capture They don't have the budget of Weta or Industrial Light and Magic so the CGI looks a bit fake.
Finally someone who explains the oscillation of a quartz crystal and adds the small detail that the frequency is not intrinsic to the material itself, but rather dependant on the shape it's cut in. Also, the "tuning fork" is usually cut out to be a bit faster, then the tips are covered in gold, which slows it down. Then the gold is whittled away until the quartz is calibrated. The clocks at 2:53 have 13-hour cycles, by the way.
His shirt is stealing all the HD bandwidth, giving him a low-res SD head haha. Just how compression works. Pretty funny though. :>

There are millions of little people in a Quartz watch making it work. They have cities and making the watch work is their job. The round battery is their sun. When you let the battery die or throw away the watch, think of what you are doing!

Interesting how one of James' favorite watches is an old mechanical Timex. I started getting interested in their watches just recently (picked up a Timex 80 because I wanted a retro-style digital watch) and would really love to find one of their vintage mechanical watches. I've yet to find one of them at any of the watch stores I've been to.

I probably should. Hopefully I don't end up hitting the same brick wall I do on Amazon and find out what I want won't ship where I live. I actually own the Casio A158W, which is the stainless steel bracelet version of the F91W. However, I've found that I prefer to wear the Timex 80 because of the better bracelet and backlight. Though what I'd really want is a vintage-style digital watch with an actual stainless steel case like they used to have. Maybe with a red LED display as well...

Yes! It returns on 30th June!
Thanks Ed :)
agree
I love the guys over at top gear, but I have to say of the three, James is my favorite.
Excellent excellent excellent
I certainly agree most with his choices of car.
A combination of both, and more. The biggest danger is that it will disrupt the heart; for that, the electricity needs to pass across the heart, so path is important. There needs to be enough voltage to penetrate into the body (skin is a modest insulator), so voltage is important. And there needs to be a minimum current, about 0.05 amps I've read, to cause the heart to fibrillate (like a seizure); currents ~>1A stop the heart entirely, which is a bit easier to recover from than fibrillation.
Agreed, James from Top Gear, and Morna Fisken from Headsqueeze would be my top two.
I can too... he just talks in such a intelligent way
How do you message James with a question?
Great
The resonance for the quartz oscillator is more complex than simply passing a current through a crystal. The crystal is part of an amplified resonant feedback circuit. The frequency can be controlled or pulled slightly through the use of a trimmer circuit for greater accuracy. The output is counted down to 1 Hz/sec. Most watches use 32.768 kHz. The very expensive watches use higher frequencies and thermo compensation for greater accuracy.

There's electronics that gets the electric pulses from the crystal via the piezoelectric effect (movement⇄electricity) and divides it down.

I used to have a Casio watch with a hidden extra feature - if you held down both buttons B and C for 15 seconds, then you calibrate its speed by up to ±15 seconds per month. (As it happens it used to gain ½s a day until I discovered this feature.) Sadly I lost it when I took it off because I was getting too sweaty playing a video game.
Thanks James. Piezoelectrics are also used in ultrasonographs.
Good vibrations : ) It's so cute that you saved all your watches. I got my first watch in 3rd grade. It had a mouse face and his eyes moved up & down with the second hand. I took it off, laid it on my desk at school, got up for some reason, leaving behind the watch and like yours, mine was stolen. : ( Fun show.

This brushed over the part about how traditional timepieces work. eg How does the pendulum on a grandfather clock stay in time?
@RizhEdits

the period of one oscillation of the pendulum will always remain the same because it isn't dependent of the amplitude.
James please talk more!
He speaks clear and a beautiful english. I know be ause I'am a Hungarian.😊
It happens to any watch that isn't plastic or coated with something. The same thing happens to metal jewelry. Gold plating will just flake off, stainless steel lasts slightly longer, and copper stains everything green, but lasts the longest out of all the metals. The watch I'm wearing right now is a Timex expedition coated with clear nail polish. I've had it for 4 months now, and it's almost time for a 3rd coat of nail polish. My dad has the same problem. Maybe a Rolex will last longer.
How would they know that the quartz vibrates in regular intervals if to measure it, you would need some other accurate time keeper to do that? And for that that one as well, and so on and so on.
That pun at 3:31
What a boss.
At 2:33 you say that a second hand on a mechanical clock moves smoothly - but why? Aren't the mechanical clocks also regulated by an object with a period of 1 second?

No they don't. They are as mechanical as quartz watches. It always amuses me how "watch aficionados" try to convince themselves and others that "quartz is soulless, simple, cheap to make" and that mechanical watches "have a soul, complicated, expensive". when it's simply not true. At the end of the day, you are wearing something that barely keeps time. Take the most expensive and accurate mechanical watch and take the cheapest quartz you can find and the quartz outperforms the mechanical all day every day. I love mechanical watches but stop trying to convince people that they are something they are not. It's just old tech that we love because it's old. It has nothing else.

James May, will we ever be able to replicate perpetual motion, or anything close to it (for example, something that would run for years without needing a refill of some kind)? My friend in my class is always planning a plan for a machine for perpetual motion, mostly including magnets, and whenever he presents his idea, our physics teacher explains why it won't work.

people much smarter than your friend have tried and failed. But tell him to keep trying , you never know he might come up with something.

All things considered, I favor mechanical clocks and watches over quartz. Quartz may be more accurate, but there always comes the day when the battery dies, and then it's only accurate twice a day (whatever time it happens to stop on) until you get another. A good mechanical timepiece, provided it's wound up and is serviced periodically, can theoretically run forever. Purely a personal preference in end, guess I'm old fashioned.

+Shipwright1918 All things considered, mechanical watches are more a hobby thing than a reliable timepiece really. They require expensive maintenance every so often (compared to a cheap battery swap) and have expensive parts which can break. As mentioned in this video they are also not very accurate compared to quartz watches. I absolutely love my Casio Quartz watches, they've lasted well over 5 years without any maintenance and are almost bulletproof (rated Water Resistant, yet dived 20M with it many times). Mechanical watches are pieces of art really.

+Drinkyoghurt Depends on the watch. The old 17 jewel railroad watches were legally required to be accurate within 30 seconds a week (for people's lives literally depended on their accuracy and reliability) no matter how they were oriented, and to this day, they are considered some of the finest kinds of watch ever made. Personally I'm happy for you that you've got a good quartz watch, if you like it and it works, good on ya. I'm still going to stick with my mechanical pocket watch. It works, it keeps time, and you say mechanical watches are works of art, I like having a bit of functional art in my pocket.

"Quartz may be more accurate, but there always comes the day when the battery dies" - I think you are wrong here. My cheap Timex's battery lasted 3+ years, it showed time, day and date. Same with other brands. Citizen produces solar/light powered watches, which will last even more. I am also a fan of mechanical/automatic watches, would love own it one day, but because it a piece of beauty. (Not for reliability/accuracy.) It will also need service if you use it for 3 years.
@Shipwright1918
7 жыл бұрын
Yes, but at the end of those three years, the battery did die, correct? So I'm not quite wrong on that point. I will admit I wasn't aware that there were solar powered quartz watches out there, neat idea! If you really want a mechanical watch,, they can be had for $20-40 on Amazon if you really want one, some of them are really quite beautiful too. That's where I got mine at Christmas, and it's still running strong to this day. I will eventually have to take it for servicing, that's true, but usually it's much cheaper to just throw away a quartz watch instead of trying to repair it should it ever conk out beyond a dead battery. Ultimately it's a personal choice. I like mechanical watches and other old tech like steam engines and typewriters, and I like to use said old tech. I could've opted for an ornamental watch to sit and look pretty up on a shelf, but that wouldn't have done me any good out when I'm out working and I need to know what time it is, so I chose a plain full-hunter mechanical watch from AMPM24 with Arabic numerals, and I use it as a practical timepiece. It works for that purpose (a watch is supposed to tell time after all), I bought it for that purpose, so I have no issue with it. Purely a personal choice of mine. If you love quartz, have at 'em and enjoy them just as I do with mechanica watches.

You can get fantastic cheap automatic watches, something like a Seiko 5 for ~$60 USD. They don't typically need a service until there's a problem. I have a Timex from the 80s that gains maybe 5 minutes every 3 days, depending on the orientation I leave it at when it's off. It's a quick fix and not bad for a 30+ year old watch. Don't hesitate looking into mechanical watches if it's something that interests you. There's plenty of cheap, quality options. Seiko is a great place to start, Japanese watches don't carry the premium "Swiss heritage" price, yet they retain all the quality.
