Hi Fouad,
Interesting idea.
Some say that A.-L. Breguet’s concept for the original tourbillon was to evenly distribute lubricants within the escapement, rather than cancelling out the effects of gravity which is the usual ‘primary benefit’ discussed. Although modern lubricants are vastly different to what Breguet had available to him, your use of a watch winder for manual wind watches has some merit.
Some of my watches are more prone to positional effects on accuracy. After a while you work out which direction to leave them overnight to speed them up or slow them down as required. Now Nicolas has planted another idea in my head regarding temperature…
So my habits are: I wind the 8-day movements religiously on Sunday (pun intended). The other manual wind watches have a little spring put in their step every 2 weeks (I can’t yet let them go for 4 weeks like Nicolas).
The last few months I tend to wear an individual watch for periods of weeks rather than changing them frequently. There is a different emotional connection and going back to a watch you haven’t worn in weeks is like discovering an old friend. Then again, this all depends on how many watches are in your collection.
I will have to remember to keep my arm in different positions during the day as well!
Regards
Andrew
