Good evening everyone.

This time, we would like to introduce a model that was released almost 20 years ago in 2003 and became a hot topic, and is now in stock for the first time in a long time. Please read to the end.
"Ref.5101P-010"
"10 Days Tourbillon" PT
The "10 Days Tourbillon" "Ref. 5101P-010" was released as a new model in 2003.
This is a derivative model of the "10 Days" "Ref. 5100" released in 2000, the year of the millennium, and is a special watch equipped with a "tourbillon" that cannot be seen from the dial side of the watch and a "10-day long power reserve".
Nowadays, it is becoming common to see dials in rose or pink tones, also known as "copper" or "salmon," but when the "10 Days Tourbillon" was first released, there was a strong impression that these colors were only used on special models. The watch we are introducing here also features a rose dial, which signifies "special," and it is beautiful yet exudes a somewhat classical atmosphere.
Although the appearance is quite simple, it features a stepped rectangular case with stepped case sides.
This is said to be a homage to the Art Deco design of the 1930s "Ref. 514." The case diameter is 29.6mm x 51.7mm, making it an impressive piece, but it is comfortable to wear, which is typical of Patek Philippe.
There is a 10-day power indicator at the 12 o'clock position and a small second at the 6 o'clock position. By the way, the small second at the 6 o'clock position has the word "TOURBILLON" written on it, indicating that it is equipped with a tourbillon.
That being said, the combination of the heavy-looking platinum case, oxidized black hands, and rose dial with applied Breguet numeral indexes is truly beautiful.
The skeleton back allows you to see the tourbillon-equipped "Cal.TO 28-20 REC 10J PS IRM".
The movement on which this is based, the Cal. 28-20/220, was first announced as being mounted on the 10 Days Ref. 5100. At the time, the power reserve of a hand-wound watch was typically around 48 hours, so this watch caused quite a stir with its 10-day power reserve.
Normally, it comes with a PT (platinum) pin buckle, but this one has been changed to a genuine PT (platinum) folding buckle, making it a great value item.
It is difficult to find buckles on the second-hand market, and currently, if you purchase a folding buckle through an authorized store, it will be quite expensive. Also, since the PT (platinum) case is heavy, it is highly recommended that they have changed from a pin buckle, which can be easily dropped when putting on or taking off the watch.
I was curious about the selling price, but this time the price was set very attractively, so the sale was decided while I was writing this article.
