โ History of Campanola and the concept of โSeikoโ
Established in 2000, Campanola has pursued the idea of ``enjoying time'' with original designs and complicated mechanisms, with the theme of ``the beauty of space''. With motifs of astronomy and the mysteries of the universe, we continue to create watches that combine artistic beauty and advanced technology.
This year, which celebrates its 25th anniversary, "Hoshi no Hibiki" has appeared as the culmination of its efforts. With the theme of stars resonating in the pitch-black sky, we expressed the brilliance of the stars and the resonance of sound. This is a special book that expresses the moment when the romance of Campanola resonates with people, and when the heart and the universe overlap.
The back cover is engraved with "25th ANNIVERSARY LIMITED", which tells the story of Campanola's history and tradition.

The transparent tone allows you to tell the time even in the dark, and the lingering sound that lingers in the space invites you on a journey through time.

The mysterious beauty of the universe is expressed by uniformly using a glossy black color that resembles the jet black of space. The gold hands, subdials and push-buttons stand out beautifully against this black color, symbolizing the brilliance of the stars. It gives off an overwhelming presence, just like the stars shining in the night sky.
โ Dial board inspired by Suikinkutsu
The concept of the dial is the ``Suikinkutsu'' of a Japanese garden. The sub-dial is designed to resemble multiple layers of ripples, creating beautiful ripples created by water droplets.

โ Buyer's comment
The moment I picked up this AH4084-51E for the first time, I was overwhelmed by its solid feel and presence. A 25th anniversary limited model, and a grand complication equipped with four major complications. Watches as luxurious as this one are rare.
The jet black body of the all-over Duratect DLC is truly space-like. The gold subdials and hands that are placed there shine beautifully like constellations. The gold gradation on the end ring is also wonderful, and the concept of visualizing the spread of the minute repeater's sound is beautifully expressed.
The moment you press the push button at 2 o'clock and hear a clear tone resonates, it's a thrilling experience no matter how many times you experience it. And when you look at the moon phase at 6 o'clock, you can feel the passage of time as the moon waxes and wanes. The chronograph also operates smoothly, providing a high-level fusion of functionality and practicality.
The Suikinkutsu pattern on the dial is also excellent. The design in which the subdials overlap like ripples has a three-dimensional effect that can only be achieved by electrocasting, and it shows a different expression every time you change the angle. You will never get tired of looking at this delicate beauty for hours.
It is amazing that the perpetual calendar does not require correction until February 28, 2100. Since it automatically detects leap years, it can be used for a lifetime without maintenance. The day and date display is easy to read, and the practicality is perfect.
The weight of approximately 160g is the perfect balance between giving it a heavy feel and not getting tired even when worn for a long time. Another great thing about Duratect DLC is that it can be used without worrying about scratches due to its high hardness.
A commemorative model celebrating the 25th anniversary and the rarity of only 250 pieces. I think this is the ultimate grand complication that brings together the best of Campanola's technology. Once you experience the luxury of being able to enjoy the four major complications at your fingertips, you will never forget it. by Fujimuro
