tighten a canon pinion?

[ramrod]

can it be done? if so, how? i don't have any watchmaker's tools.

i have a seiko 7006 watch with a very loose canon pinion, i believe. when i set it, the crown turns without any perceptible resistance. it's rather annoying because i'd like to feel something there as i set the watch.

Does the watch keep time?

hey jc....yes it does. there seems to be no problems with it.

I wouldn't tighten it then. Even with the proper canon pinion tightening tool, it is easy to over tighten and then you'll have to find another canon pinion. I did this twice on the same watch. If it starts to lose time, then you can cross that bridge, but for now I would suggest you let it be.

If the watch keeps time then the cannon pinon is tight enough to carry the hands.

Hi,

    I agree if watch is keeping time the canon pinion is fine however yesterday I ran into this servicing an Old Waltham and thought you all might be interested in seeing a really worn out canon pinion. Amazingly enough watch still keeps time.

[ramrod]

all righty, then. i'll follow consensus. i'm not worried about it at all.

on that note, what would dictate the need to tighten it? how would a watch perform with a loose pinion?

Would lose time because of slipping.

The cannon pinion should be friction tight that's all. the main cause of it being to loose is the hands won't carry round or will move in fits and starts but the watch will still go and it will run right down. If the canon pinion is too tight it will stop the watch.

Hello,

A loose canon pinon would cause a loss of minutes in a day...I had onw situation where the watch would lose 20 minutes between marking 7 and 8....within an hour. When you start to see large chunks of time delay, that's the canon pinon.
