A bit of a slam-dunk for the old over-winding argument.
Thanks.

Thanks Graham, a very interesting article.

Agree. Good link, G!

Great info, can't wait to correct my Dad when I see him next week - he is obsessed with not "overwinding"!

So why do watch makers warn against fully (or over) winding automatics? E.g. from a Christopher Ward owner's manual:

Never fully wind your watch if it stops, 10-15 revolutions should suffice to have it restart.

The use of "Never" suggests to me that it's bad to fully wind an automatic whereas the article above concludes that it won't damage the mainspring and you're unlikely to wear out the barrel's inner wall.

Being new to watches,I found this very informative. Need more easy to understand articles.

Look's to be a good link.

Cheers

After reading the article I think I'm going to have a word with a colleague of mine who has a Speedmaster who is obsessed with over winding

If I'm not wearing my Speedy,it sits on the Winder. Keeps running perfectly,never need to do do any manual winding.

Only some SpeedMasters are automatic. Most are hand wind.

Nice article. I still worry about overwinding and using winders.

Great link

From what I have heard, the hand wind mechanism in an automatic is not designed to be used extensively, it is made of parts that are not durable enough for regular use. So regularly winding your automatic by hand may damage the mechanism over time.

The thread was extremely detailed and informational...I didn't know that it wasn't really possible to over wind a mechanism. I guess when it comes to down to it, time kills all things.
