TIL that the automatic winding mechanism of analog watches is called
Automatic Quartz. It is a wonderful intricate system, and I love the delicacy, yet robustness, of the implementation in watches, which can last way more than five decades

Don't let the name fool you it's not fully automatic.
Your wrist needs to shake the watch, sometimes every few weeks, sometimes every few months, because energy needs to be put in the device before it can be radiated through the whole watch. So You charge it with Potential Energy. The system creates rotational speed which can go all the way up to 100,000 RPMs this is coupled with a generator which is coupled to a set of slow discharging capacitors that electricity Powers your beautiful analog watch

#Asthma today.

I’m alone this weekend, the better half left yesterday morning to look after family again.

The #alpacas & #lambs rushed the lucerne this morning - looks like more rain is coming. Are they preparing?

Wearing an “new old stock’ #Seiko #kinetic #watch today. It’s the watch you never really hear about - it’s like a quartz watch & an automatic had a baby.

It arrived from #Penguin in #Tasmania yesterday. The trip took 10 days after being received by #AusPost.

Is Penguin remote?
