Oh, that´s what the double third wheel is made for
G'day,
regardless the attachment of the wheel driving the second hand, amplitude and performance will always be the same.
As noted, that´s what the double third wheel is made for; the second hand pinion always engages the same wheel, eliminating the need for intermediate wheels and pinions. Subsequently it´s always the same friction and torque.
Does this clearify?
Cheers,
Peter
Some thoughts on the new ref. 25820 Vintage45 "Square" and GP´s new caliber 4500
Dear enthusiasts, following up to our previous introduction , i´d like to have a closer look at GP´s new pre-SIHH introduction reference 25820, dubbed the Vintage 45 "Square" or "Carree": Vintage 1945 Carrée At the beginning of the 90s, well before "vinta...
Part 3 - some more details of the new caliber GP4500
As we´ve seen, the new GP4500 caliber incorporates some practical, new solutions to improve the efficiency, longevity and durability of this movement. It is promising to be an accurate, sturdy timekeeper for a long time to come. But is it a nice movement ...
Thanks a lot for this exciting pics and insights
Peter, that's a great thing what you're again doing for us! Amazing pictures I love very much. And I'm particularly glad to learn about and understand now this movement in a way I would like to be able to understand the 3XXX mvts. as well, which have not ...
Oh, there´s something for you!
Hi Alexander, thank you a lot! That´s much appreciated and the pleasure is completely on my side! In terms of the GP3xxx range, have a look here. There aren´t many chances to get much closer than this: http://www.tp178.com/jd/gp/article1b.html Sure it´s n...
Indeed,
thanks again for this hint, I didn't note this study before, best wishes for the feast days, Alex
Thank you Peter
Hello Peter, first I wanna thank you for this indepth look. I was wondering about how GP will provide the same moment with the central second position with a double third wheel, but with the second at 9 with a singular third wheel? Because in my opinion t...
Like this?
Hi Philipp, something like this? These are prototypes and in fact the GP4500 caliber with central second! While i can´t share details on upcoming models, at least it seems such is being evaluated very closely... Does this help a bit? Cheers, Peter ...
More technical...
Hey Peter, hmm... that's not really what I meant, but also nice pictures of course. In part 2 you showed us a picture with details of the different variations of seconds. And if GP produces the second at 9 they perhaps will have different torques and thou...

We're getting closer :o)
Hello Peter, yes in this case you're right. But what if you use the second wheel to display the small second at 9 without the second hand pinion like on the picture with only a single third wheel. You definitly will have less engagements in your going tra...
Well, i think that´s not possible
G'day, i´m rather tempted to trust GP´s engineer in this one Actually attaching a seconds hand onto the second wheel is a rather unconventional thing to do and as said, regardless the position of the second hand there´s no difference otherwise. In this i ...
Hi, Philippe,....
....I believe GP opted for this design for beeing flexible and vesatile. Of course one could use the classical small seconds design and use the fourth wheel directly to display the second. But, than you're also bound to design the train around it - i.e. o...
The black dial looks smart
Can't wait to "feel" it on my wrist thanks Peter cheers joe
