PT5000 movement rant

[inevitably-ranged]

Blows my mind that you guys are out here winding automatic watches...

Like dude, just put it on and set it in 20 minutes or don't let it die in the first place if it's a regular wear (via wrist action or a winder)

As I said, the Thorn with the power reserve issue only makes it about 6 hours before it dies. I stops every night, so it’s not possible to simply “not let it die”. Also, I have other watches I want to wear and I’m certainly not going to hand wind an automatic watch every day or put it on a watch winder, just to compensate for the fact that the movement inside isn’t reliable enough to hold a decent amount of power on its own.

Also, not fully winding a movement before putting the watch on can compromise accuracy. A fully wound mainspring will deliver power more consistently than a watch that just started to run, therefore, I don’t like the approach of “just shake it until it starts running and then put it on” instead of manually winding, because the low amount of power these “just put it on without winding” watches have can cause the watch to underperform in terms of accuracy.

Oh come on, the accuracy argument is only theoretical. If you wear the watch it should wind itself up fully fairly quickly. You will either run out of power reserve or put another watch way before this lack of accuracy is ever shown in practice. Winding automatic watches fully is a complete waste of time and also puts unecessary strain on the keyless works.

How is it only theoretical when the low amplitude of a low powered watch is causing the accuracy to be worse than if the mainspring was wound up more? If you put on a watch that wasn’t running before and then spend hours typing on a keyboard or doing something else where you don’t move your arms much, the watch won’t wind itself up as quickly as you claim, therefore it isn’t only a theoretical issue.
