torque

the manual/instruction booklet for mine does not state how many turns of the crown are required to start the watch .

just to fully wind it-having said that...
it does take a lot of winding to get sufficient torque in the mainspring to get to the escapement and the beating heart to start.
the origins of this calibre may have something to do with it.
shaking a watch-is a no no can create even more problems 
a gentle flick in the horizontal position is normally all that is required (any more and there is a problem)
to get the pallet forks to unlock and start operation
mine i love as it hacks and is very very accurate.

Issue with The JLC Grande Reverso 976 Movement?

 
 By: charsiewfan : November 17th, 2021-07:38
Hi all, Recently got myself a pre-owned 976, and I encountered this strange issue which I have not seen with my other manual-winding watches. It appears that for this movement - which I have also seen in old forums posts on other sites - needs to be "kick... 

Some Movements Are Like That

Depending on the movement, some need more 'help' than others. Do you know when the last time your timepiece was serviced? If it has been more than 10 years it could need a nice refresh.

Thank you.

I do not have the full service record, but based on the registration date it is less than a decade old. Will consider sending in the piece for some maintenance, nonetheless!

Great to hear from an experienced collector!

Gives me some comfort. Maybe I am lucky with my other manual-winding pieces to avoid this situation. Thanks!

Yes,

I’ve owned a Reverso with cal 976 and don’t recall having this “issue”. However, I own a large collection and a couple of my watches (other brands) have the same characteristic, just need a gentle shake to start the movement. Hasn’t bothered me at all. ... 

Comforting to know.

Sounds good to me, thank you. Again, maybe I am lucky with most of my manual-winding pieces so far..

I have at least a half dozen watches that need assistance to start running

Out of about 100 or so. My suggestion, and that of my watchmaker mentor, is not to worry about it. Cheers Mike

Ah yes, I mean gentle flick.

Not going to be too rough with a slightly delicate piece, haha. Maybe I am just spoilt with pieces needs only a few turns to start running. Thank you, nonetheless!

This happened to some of my other manual winding before too

Not to my Reversos so far but other watches like the Lange 1. After sending for service the issue stops. My watchmaker told me one of the reason is dry oil. After oiling during servicing, this doesn't happen again. I'm not technical so I took his word for... 

Thank you Robin!

Might be a sound decision to send my timepiece in for some maintenance sometime soon
