I have to say I'm thrilled!
To everyone who doesn't know what an automatic watch is:
This watch has no battery. It works mechanically via sophisticated mechanisms and is driven or 'charged' by the movement of the watch, via a flywheel. Therefore, you should wear such a watch in this case even more than 12 hours a day to guarantee that the watch is charged enough. For me, just a few hours was enough, depending on how much you exercise. Alternatively, there is a rotary knob with which you can open it manually.
The time is therefore not quite accurate and can vary up to 1 minute a day. Usually it is less. These are the disadvantages of an automatic watch, but for every technology enthusiast it is all worth it!
Such a watch is so complex and has so many gears that you can only guess how exactly it works despite the two glass panes (front and back).
I think they are very well made. After adjusting the strap, it fits like a glove - the necessary tools are included in the package and you can only need a hammer extra, otherwise everything you need is included. And for its type and processing, it is actually a bargain!
PS: I can't judge how well she tolerates water, since I take my watches off before showering or swimming, but I suspect that due to the lack of electronics, it should make little difference to the function, but it can be easy that moisture diffuses through the large glass and you can no longer get it out. I don't want to test it!
But a 5-star product for normal consumers!
