So, these watches are all pre-sold and we can't buy one? When would be able to buy a watch with this innovative mechanism?
It's likely that this is a paid post. And if that's the case, then I think it's money well-spent, as this is a beautiful post and an effective advertisement.
Only 10 have been made and all have been sold for some exorbant amount, so mostly it’s genuinely motivated coverage of some cool tech.
Ford doesn't make GT's because they're profitable. They make them to sell Mustangs.

How does the spring drive actually work? What is the mechanism which keeps it moving at a consistent speed? A quick google only turned up rather vague descriptions.
At the heart of every mechanical watch lies a coiled spring. Within that spring energy is stored that wants to be released. This energy is released through the wheel train, which is a set of cogs with reductions (some of them attached to the hands). Left to its own device this system would just spin as quickly as possible until the spring is unwound. To prevent this, somewhere in the train there is something called a…
What i don't understand is exactly how the spring drive keeps the wheel moving at a constant speed.
I appreciate that this involves magnets, and eddy currents induced by those magnets, but that's a description, not an explanation. What is the mechanism, physically and mathemetically, that keeps the speed constant?

I understand (roughly!) the basic idea of a watch mechanism, and how mechanical escapements work. What i don't understand is exactly how the spring drive keeps the wheel moving at a constant speed .

The integrated circuit counts how many times the rotor has spun compared to how many quartz crystal oscillations have happened and adjusts the electromagnetic force somehow. My guess is by increasing/decreasing the power passing through some resistor (creating heat).

Do analog watches have any applications to begin with, these days?
EMP resistance. This isn't exactly a practical justification for most uses, of course.
A sundial is what you need.
I wonder what are the mechanical properties of the case material (aluminium foam filled with plastic). This seems like entirely new class of composites.

I've played around a bit with such super light metals and aerogels as well, they are very interesting materials with surprising properties.
Not only is the content incredibly interesting, but that website layout is perfect. So clean. The ads page is interesting: > The typical HODINKEE reader holds a master’s degree or higher, browses from his professional office, earns more than $200,000 per year, owns seven watches, and purchases, on average, three watches per year with an average value of $7,000 or higher per watch. An attrition rate of three $7,000 wa…
Do bear in mind though, even very wealthy collectors also regularly sell pieces and 'trade up' over time. You can only wear one watch at time after all... unless you decide to start 'Schwarzkopfing'

There's one basic question I couldn't figure out from the article. Where is the spring that you wind up and that stores the "power reserve of about 60 hours"? Is it part of the silicon? Or is it external? I figured out that the three crescent-shaped parts are springy ("flex laterally to provide a restoring force as the oscillator vibrates through six degrees of amplitude"), but it doesn't look like there's anything e…
This video may help, as you get to see the movement in action: https://youtu.be/xWh0p9Irznw It doesn’t clearly show the mainspring, however at around 10:45 you can see the small gear spinning. That is being driven by the mainspring, and if you removed the escapement it would spin super quick until the mainspring was unwound. It’s the constant rocking back and forth of the regulator that limits the speed that small ge…
