Is there an issue of over winding 233?

[psilow]

Is there a clutch that prevents over winding?

From another site, I read that:
"Feedback from service centre people say that 233 mechanism will not last long due to constant winding. Richemont Luxury Ctr also feedback that many 233 has been sent back for repairs due to broken mainspring & stem due to constant over-winding."

Dumbest thing I've read here in a long time.

well i am sure the 233 is a manual winding movement. Thus over winding is easily done. having never owned a panerai but other manual winds i know this problem does occur. after a certain amount of winding you should feel some strong resistance - you should stop then ( or does the panerai not have this feature)

Well at least on my PAM177 there is a clear stopping point in winding to limit to winding, at that point you just can't wind beyond, so I can't see why this might be a problem with other Panerais

Of course, and with a 233 you have the big "shark's tooth" power reserve meter on the front of it. You'd have to be a moron to overwind this model.

I will never say never but my 233 has a clear endpoint.

In actuality the 8 day reserve actually last 10 days when fully wound. Therefore the 8 day gauge is conservative and the watch can be wound past it.

While the p2002 is a 10 day movement, the power reserve indicator isn't calibrated to 8 days, it's min-to-max. So your point that upon reaching the max on the power meter indicates only 8 days of power and can be wound more is simply wrong.

If you say so buddy.

I guess you slept through science class. On planet earth my 233I when wound to the eight day marker or end of the indicator last 8 days... imagine
that. When I wind it extra after it reaches the end of the indicator I get 10 days. I have done this countless times and am only stating my observations.

As they say, no point in arguing with a moron.

i have no idea but if Brainbizz has tested it and has had ten days power reserve the why would he be lying about it?
genuine question

Hi Chris,
Yes, it has a 10 day or at least a 9+ day power reserve (WatchTime review). I thought we all agreed on that. It's made that way. The "8 Days" and the 8 increment shark's tooth (center is four) power reserve is a "tip of the hat" to the brand's legacy.
Since this has to be discussed in the context of the OP, I said that while it's easy to sense full winding, the power meter showing "full" was a back up. That reflects "8 days" on the power meter (FULL) and over nine days in practice -- not that that's the point anyway. Second pic shows it fully wound (can't wind it more) or at the "8 Days" point, if I cared to check it, it would be running longer than that.

Edit: Final point I forgot to include. The power reserve meter has been shown not to be linear. In other words, it doesn't measure elapsed reserve uniformly. That's why I consider it is a "min-max" indicator. If anything, the watch will run after reflecting zero, something Panerai didn't encourage as, despite the three barrel main spring system, the watch won't hold spec at the lowest end, or below the power reserve indicator.

From Watch Time:
Panerai uses three serially switched barrels to minimize the difference in torque throughout
the duration of the power reserve. Furthermore,the brand’s watchmakers developed
their own special testing procedure: the accuracy of the rate is monitored in each of the usual
positions when the watch is fully wound, then checked again seven days later. The amplitude
must remain between 170 and 330 degrees. The greatest deviation of rate at both
measuring times is calculated according to the CTMP (Contrôle Technique des Montres Panerai)
formula, which gives 50 percent greater weight to the later measurement. The tolerances
are rather lenient: a watch with a 10-second greatest deviation of rate among all the
positions when fully wound on the first day, and with a 20-second deviation after seven
days, would satisfy the minimum requirements of the test. All of the test results are
recorded in each watch’s guarantee book. The watch that we tested performed significantly better than
the hypothetical one described above, just as we expected when we discovered that its daily
deviation on the wrist remained within the relatively narrow range of +2 to +5 seconds. On
the timing machine, the greatest deviation of rate was also fairly small: four seconds among
the several positions when fully wound and six seconds after seven days had elapsed. The decline
in amplitude after seven days and the consequent tendency to gain were clearly measurable
but by no means dramatic. The average deviation after seven days was approximately
seven seconds. Those who are fanatical about the accuracy of their wristwatches shouldn’t
use the full extent of the power reserve.

okay i get it now


lovely watch by the way!

YAWN....I am stating my observations based on the laws of physics. There is something known as the scientific principle where one makes a hypothesis and then uses scientific methods to prove or disprove the hypothesis. I realize that this may be a stretch for you and you can quote Panerai, Watch Time the Bible or whatever you like. Linear non linear who cares. I wind my watch to the end of the meter I get approx 8 days + or - a few hours period. (That is one day longer than a week) If I want more I wind it after it reaches the end of the indicator which gives me more than an extra day. Let me show you a 10 day reserve indicator, notice that it is longer. I know different movement but interesting observation.

Exactly!!

[Launch Mini]

Pretty sure my 233 doesn't have a clutch to prevent overwinding.
It does become tight when fully wound.
Now , if i tried,pretty sure I could crank a few more turns of the crown after it reached the stopping point, but the would not be good.
Yeah, you do get over 9 days, but the meter is like a gas gauge, once on empty you can go a lot futher if you want to try.

[brainbizz]

Good analogy with the gas gauge. My point is that once the "tooth" is at the end of the indicator there is more. I get several more winds when it reaches the end. When I feel good resistance I stop. I am just stating my observations with my watch. I wind it wear it a few days and check it later out of curiosity in 7 to 10 days. It is not so complicated. The poster asked a reasonable question for which I was providing my observations with my watch.
