Howdy,
i think it is and while GP is not comfortable to release production figures, i think it´s ok to say there is not that much more than a dozen pieces world-wide. It´s a very complicated watch to do, not just an expensive one... 
With thanks to Mrs. Ute of GP Germany for allowing an even more rare view on the wrist:
The watch measures 42mm in diameter and 14.15mm in height, making a really substantial piece beyond the "inner values". On a closer view, the dimensions and particularly the height is easily overestimated, a little bit of a chunky piece of metal:
The massive Pt case accounts for a heavy piece, but it still is very wearable and almost inobtrusive.
To me, the wrist shot puts things in perspective. It´s made to be worn and on the wrist, it doesn´t look like big bucks on first glimpse.
Ok, another view of the back:
(because this is a privately owned watch, i´ve digitally removed the individual number)
Oh my, details of the movement...
I really can´t claim to know how it works 
Based on the position of the vertical wheel, i´m tempted to guess it to be part of the keyless works and winding mechanism. Much of the movement is located on the dial side and usually not visible, apart from the tourbillon carriage and the hammers for the chime.
What i find a very nice thing is the incredible depth; there are so many layers and recesses filled with levers, wheel and springs! It´s inviting to be admired and begging for a close look, a spectacular view taken to the top when things start to work. It´s much like an orchestral work of mechanical parts, in some way "kinetic art".
On the model, it´s a GP "Opera TWO". The features sum up for tourbillon with perpetual calendar and a minute repeater with Westminster chimes ("carillon") by use of four hammers and gongs.
So yes, it´s pretty special 
Cheers,
Peter



It´s a big piece (42mm wide, 14.15mm high), but filled with truly a LOT of small parts:
Frankly, i´m undecided about the finish and personally find the Three Gold Bridges to be a bit finer.
But i think it would do equally well and comparably impressive without any decorative work at all; it is the work to make it work that isn´t without impact if you have a chance to see it up close.
And to make it sound nice, which this one did featuring a nice pitch and tone, but great volume despite the sheer weight and mass of the heavy case, is quite a trick!
It just doesn´t look like a repeater on first view?
I find it quite mesmerizing 
Cheers,
Peter

Yes, it´s pretty unusual not only because of the functionality!
And not a "traditional" repeater, obviously
On new models, i´ll do my best to see if there´s something to tell.
Well. If you look closely at the posts of the last two weeks, you may see something new already. A much more "simple" watch than the Opera 2 maybe. But still nice and classic, very "GP"
And if you don´t tell, i´d sugeest to have a look at the answer regarding the Vintage45 GMT chronograph below (may tell a bit too).
I´m afraid that´s for now, apart from, hmm, the pics of Opera 2 (and Opera 3, to come soon) may or may not be choosen intentionally!
Nonetheless, from what i´ve heard there will be very nice surprises for collectors over all the portfolio by GP, from the more affordable pieces up to wild, stunning, fantastic, evil-like expensive fun watches!
Cheers,
Peter
