Oh, there´s a lot!

Hi Jacky,

there´s a couple of differences; first of all, it´s quite a bit larger!
Thus it seems to fit a larger case (which the "Square" is, at least in terms of available space) better than the ultra-thin GP3000 calibers. Other differences are the winding system and the double 4th wheel. This allows for different driving of the seconds hand, which will not "skip" as some pieces with an indirect second did. It allows for an unusual layout as well, so there´s some room for creative dial designs.
The main difference is the barrel; the GP4500 makes use of a lot larger barrel and in fact, the whole movement was designed "around the barrel". That´s of benefit for power supply and subsequently, timekeeping.

We´ll have a closer look in the near future!

Cheers,

Peter

(GP NEW MODELS) Reference 25820 is for fans of the Vintage45 line

 
 By: PeterCDE : March 14th, 2007-21:57
interesting details: - case proportions, 32 x 34.20mm - date window (not sunken!!!) - seconds hand position at 10 In a nutshell, the new ref. 25820 "Vintage45 Square" accompanies the 2006 "Triple Calendar". The second extension of the cherished Vintage45 ...  

Lovely !

Thanks for the Vintage preview Peter.

It's nice that they fixed the sunken date feature. Not so sure I like the layout of the dial with the sub-seconds at 10 o'clock and date at 5. It's certainly a contemporary layout. Do these models replace any of the current Vintage line, or are they addit... 

The date is really special!

First of all, the small seconds hand is driven directly out of the movement - one major benefit of the GP4500 caliber, which overcomes the deeply sunken date wheel and is a nice view in the same degree: As far as i understand, the "Square" is an addition ...  

A great photo Peter, thanks for the additional tech. info.

I appreciate the technical highlights on this new piece. Maybe once I see actual watches, the unique placements of the date and sub-seconds will look better. I've found actual photos and seeing in person is a big difference for many GP watches. I'm sure t... 

square watch case

I hope the square case is only an additional to the current line-up. Personally I found the "King Size" case more traditional and elegant. It is also quite modern due to its size. The additional power reserve is most welcome.

I agree with you

Great picture, thanks Peter !!!

Always stunning to see those close-ups you pull out! Cheers, Christian

My pleasure! One more...

More to come during SIHH; there´s a couple of interesting details! Cheers, Peter...  

Putting that sub second at '10' is really unique and beautiful...

Not bad a watch at all... Especially this rosegold version...classy! Sapphire case back for all models including SS? Regards

Sure

 
 By: PeterCDE : March 28th, 2007-11:11
Hi Jacky, all models will come with transparent backs! I´m sure you will like it Cheers, Peter

One question Peter.....

 
 By: Jacky : March 28th, 2007-11:17
Whats the difference or good points of the Cal 4500 apart from the clearer date as compare to prev Cal 3000 ranges? Thanks... Regards

Thanks for the quick input =)

Very clear explanation Does the bigger barrel means longer power reserve? Probably right? Regards

That´s correct!

 
 By: PeterCDE : March 28th, 2007-13:08
Hi Jacky, indeed the power reserve is a bit longer! For example, the Vintage "Kingsize" ref. 25830 with GP3300 caliber offers a power reserve of 46 hours, while the new "Square" with GP4500 caliber comes with a power reserve of 56 hours. This is mainly ac... 

movements parts

 
 By: vlkcheng : March 29th, 2007-03:13
I've noticed GP uses a lot less parts for their movements compare to other movements. Am I right to say GP movements are less complicated without meaning less reliable or too simple of a movement??

A lot less?

 
 By: PeterCDE : March 29th, 2007-05:28
Howdy, well, which movements do use significantly more parts? Unless you compare it with a Grand Complication Seriously, the new Omega 8500 ("Hour Vision") constitutes of 202 parts, the JLC 875 ("Autotractor") is made of 218 parts. I´m not sure how many o... 

I've always admired GP3XXX movement...
