Good evening everyone.
This time, we'd like to introduce the new Split-Seconds Chronograph "Ref. 5370P-001," which has arrived after a long time! And what's more, we've also just happened to have the current model "Ref. 5370P-011" in stock, so we'll also be introducing it briefly! Please enjoy until the end!
"Ref.5370P-001"
"Split-Second Chronograph" PT
The "Split-Second Chronograph" "Ref. 5370P-001" was announced at Baselworld in 2015.
This is a very elegant model with a platinum (PT) case, a genuine black enamel dial, and white gold applied Breguet numerals. Another major feature is the inclusion of a single-function "split-seconds chronograph," which was unusual for the current collection at the time. I still vividly remember being deeply impressed by its perfection and impact when it was announced.
Here, for those who are unfamiliar, I would like to briefly explain what a split-second chronograph is.
Watches equipped with this function have two chronograph hands, one above the other, which start moving simultaneously when the start button is pressed. Next, when the "split button" is pressed, one of the hands stops, while the other continues to move.
*In the case of "Ref. 5370P-001", this split button is located on the crown.
After reading the intermediate time (lap time) with the stopped hands, press the split button again and the stopped hands will instantly catch up with the moving hands, and they will once again overlap. This "catch-up" movement is so bold that many first-timers may think it will break, but it is actually controlled by extremely advanced technology, and this is the correct operation. It is one of those complex mechanisms that truly embodies the essence of mechanical watches, and it is a function that every watch lover dreams of at least once.
One of the things that draws you in when looking at this watch is the dial. This dial is made using the traditional technique of "honkoku cloisonné," which combines metal and glass, and its beauty is overwhelming to the viewer.
This model features a black enamel coating applied to a white gold (WG) disc, which is then fired at a high temperature of approximately 850°C. After cooling, skilled artisans meticulously polish it by hand to create that mirror-like luster and depth. Even when viewed through a magnifying glass, the surface is completely free of any irregularities or irregularities, making the finish truly "perfect." Furthermore, the indexes feature applied Breguet numerals made from white gold, and needless to say, this combination is incredibly cool.
The 41mm case and split button at the crown position, combined with the solid feel of the PT (platinum) case, create an impressive finish.
This particular watch has barely been worn and is in excellent condition. The case is unpolished, retaining its original finish, and was overhauled by the manufacturer in September 2025, making it a watch you can use with confidence.
The hand-wound movement, which can be seen through the skeleton case back, is the "Cal. CHR 29-535 PS," which is designed to improve gear transmission efficiency and minimize friction.
This three-dimensional movement is like a work of art, and just looking at it has a beauty that draws you in. Some people say, "I could drink alcohol while looking at this movement," and I can understand that feeling. (laughs)
The warranty is dated December 2015. While there are some minor scuffs associated with use, there is little sign of wear, and the case and buckle appear to have never been polished, remaining in very good condition. All accessories are included, including a replacement solid case. This is a very good example, demonstrating how well it was cared for by its previous owner.
The selling price is 25,850,000 yen (tax included)
As mentioned at the beginning, we also took a photo of it next to the Split-Second Chronograph "Ref. 5370P-011" with a blue "Grand Feu Enamel" dial, so please take a look!
Opportunities to find the same model with different dials are unlikely to come up in the future. If you are considering purchasing this model, please feel free to contact us.
