The entomologist kind.What kind of a sadist are you?
I'll allow it.Maybe not quiiiite what this thread was intended for, but what the hell. Got myself one of these:
That counts as a watch, right? ... right?
Nice!Not for me but since Junior becomes a teenager on Saturday he is getting this bad boy for Christmas.
Breitling 80's and 90's quartz chronos have miyota movement's and those cost 2-3k?. Service cost's 700? and it is new 15? movement and cleaning of parts. But in defence, it is Breitling and when it came out, miyota movement wasn't 15?'s.Well, it's a custom casing for a miyota quartz movement. They shouldn't be really expensive.
Not likely enough to be of use. Seiko Kinetics essentially do this- they use a mechanical oscillating weight like a mechanical automatic watch which drives a dynamo to recharge what is now a lithium-ion rechargeable cell (originally they some type of capacitors, but those were found to fail too frequently and had a short service life). Most of these watches will run without additional input for 4 weeks to 4 months depending on the specific model (some newer ones have a feature that shuts off moving the hands after a certain amount of time without movement but continues to keep track of the time and will jump the hands to the correct position once moved again to conserve battery life, and they can keep track of time for up to 4 years this way). Compare that to the capacity of an equivalent silver oxide cell in a watch which has a lifespan between 18 months to 3 years of constant driving in typical watches. I don't think there's enough energy potential there given the size requirements.I wonder just how much a dynamo would be able to recharge a li-pol battery. Judging by some horribly failed similarly conceptualized battery packs, probably not that much. Plus, it would only add bulk and it would be positioned right where a bunch of sensors are.
Not terribly surprising. Quartz watches operate using tiny magnetic stepper motors, too strong a magnetic field can cause erratic behavior, stop the watch, or even permanently damage it if the field is strong enough to change the properties of the stator and rotor. This is also the reason a quartz watch should never be demagnetized. In any case, when this happens there's really no way to repair it short of replacing the magnetic driving components, and to my knowledge those sort of components for the movements in Ecodrives are not available. It would have to be returned to Citizen where they would probably replace the entire movement. Quartz chronographs typically use several stepper motor setups so they are able to independently drive multiple features at once, so it's certainly possible to damage some of them and not others, falling right in line with what you said happened.On the topic of breaking watches:
A co-worker and I own Citizen World Chronographs (picture), which are basically digital watches made to look like old school mechanical ones. And he managed to break his watch while he worked near the generator of one of our X-ray tubes. But not in the way you are probably thinking right now.
In short, the generator transforms 400 V AC into up to 60.000 V DC. At some point during that conversion there are two big coils involved. These coils produce a somewhat noticeable magnetic field. Turns out that field was strong enough to break his watch. After he was done, only the minute-hand still worked. Everything else was dead.*
*everything else on his watch. He obviously survived.
