Good evening everyone.

Time flies, and before I knew it, there is only one month left this year. Maybe it's because I'm so busy every day, or maybe it's because I'm getting older, but I feel like a year has passed really quickly. (laughs)
Well, today we would like to introduce a rare and popular model that is the first arrival in our store! What's more, it's a "single shield"! Please enjoy until the end!
"Ref.5971P-001"
"Perpetual Calendar Chronograph" PT
The "Perpetual Calendar Chronograph" "Ref. 5971P-001" was discontinued after about two years from 2007.
The bezel, generously set with 36 large baguette-cut diamonds (3.88 ct), makes this watch even more eye-catching, and the layout of the calendar, sub-dials, and moon phases on the dial, as well as the tachymeter scale written around the outer edge of the dial, all create a perfect balance.
It can also be seen as a derivative model of the "Ref. 5970," but its true positioning seems more appropriate as a successor to the "Ref. 3990."
To talk a little about the "Ref. 3990," the case design and mechanism are the same as the "Ref. 3970," and it is available in all materials (18KYG, 18KRG, 18KWG, PT).
The basic design is very gorgeous, with diamond-set dial indexes, luminous leaf-shaped hands, and a bezel set with baguette-cut diamonds. It is said that this watch was produced from around 1995 to 2007, but the production numbers were extremely low, making it a rare model.
The 18KWG (white gold), 18KRG (rose gold), and 18KYG (yellow gold) models feature a silver dial with black calendar display, sub-dials, tachymeter scale, and chronograph hand, while the PT (platinum) model has a black dial with all of the various markings on the dial written in white, giving it a cool look and excellent visibility.
Although it may be a little difficult to see, the pin buckle is also adorned with six baguette-cut diamonds (approximately 0.3 carats), as befits a special model. The "Ref. 5970" uses a folding buckle, but this model is designed with a pin buckle, which gives it a classic feel and makes it very attractive.
There is also a diamond on the side of the case at 6 o'clock, which is proof that it is a PT (platinum) case. This is one of the points that only the owner can enjoy a sense of superiority.
The movement that can be seen through the skeleton back is the famous "Cal. CH 27-70 Q", an ebauche version of the Lemania chronograph movement "Cal. 2310".
This highly refined movement, created using Patek Philippe's technical expertise, is so captivating that you will never get bored of looking at it, no matter how many times you look at it.
The warranty date is May 2010. This is a recommended item that comes with all the accessories such as booklets, closed back, and adjustment pins.
And as for the selling price, I wanted to say, but the sale was decided soon after it arrived.
Unfortunately, since it was sold before it was even listed on the website, I can't provide any more details than what's written in this article, but I think anyone who manages to get their hands on this model will definitely be very lucky!!!
