Tutelary watch winder

[Ray Singh]

I bought a Tutelary watch winder from Ebay sometime ago. It works great and is very quiet.
Its standard function is to rotate the watches for 1 hour and rest for three hours.
If i leave my classic Omega and Porsche design by IWC on there day and night for weeks at a time am i over charging them? I understand there is a clutch inside the watch to prevent over charging, but am i in danger of wearing this out?

I could put a mains timer on the plug socket if i am damaging my watch?

They'll be fine.

The clutch can be worn out but only from lots of over use best speaking to your watchmaker about that.

I have one of these winders, don't know if it does any harm, but even 1hour on, 3 hours off was way more than my watch needed to keep running. I bought one of those cheap mains timers to turn it on and off. I only need it on two hours a day to keep my watch running.

Thanks for the replies. I will use my mains timer to stop the over winding. I will try it for a couple of hours per 24 hours as a starter.

Ive now set it up with a mains timer. 3 hours actual winding per day at regular intervals.

I did see that both my watches require 645 turns per day, so i might have to sit and count how many turns per minute it is making.....

You cannot over wind a modern automatic watch. Automatic movements have a clutch system so when the mainspring is fully wound the winding mechanism slips. Otherwise you would over wind your watch by wearing it on an active day! How exactly do you control the rotations of the rotor whilst it is on your wrist?

The 645 turns is most likely a recommended amount to fully wind the spring over the course of a day ... I definitely wouldn't read too much into it.
