Model: Campanola BU0020-71E Eco-Drive with Moon Phase and Triple Calendar
Year: December 2024
Features:
The Name. The BU0020-71E is part of Campanola’s Heaven Filled with Stars collection. However, instead of the more commonly used gold leaf, the stars scattered across its urushi lacquer subdial are crafted from crushed Mother of Pearl. It’s a stunning design choice, made even more eye-catching by the watch’s blacked-out aesthetic, and it gives the watch its name - Amairo Hoshi (天色星), meaning Heavenly Stars.
The Details. It’s one of the newest celestial offerings from Citizen, and unlike the previous variants, the moon now features eight layers of paint, giving its craters a rich, three-dimensional depth. Someone recently asked me why details like this, typically only noticeable through a macro lens, matter - and that’s a fair question, but one that has a simple answer.
The Craftsmanship. Small details reveal the watchmaker’s pride in their work. Whether it’s decorating a movement hidden behind a solid caseback or meticulously layering a moon phase for heightened realism, these extra steps demonstrate a level of craftsmanship and diligence that tends to carry through the entire project.
Layered. Campanolas are renowned for their use of layering, often opting for a distinctly three-dimensional look, as I’ve tried to demonstrate with the photos and video of this watch. As much as I love their cosmological dials and features, the thing that continues to draw me into Campanolas is their stacked approach to design.
Eco-Drive. Very few watches offer the same level of convenience and reliability as Citizen’s Eco-Drive. The six-month power reserve that can be charged from only 19 hours of sunlight. However, there has always been one downside - the dials must have a translucent surface to allow light to reach the solar capacitor beneath. As a result, the design possibilities for Eco-Drives have always been somewhat limited - until Citizen began experimenting with translucent bezels. As solar charging technology improved, the size of the capacitors shrank, meaning Eco-Drives only required the outer edge of the watch face for the charging element. This innovation led to the creation of Campanola Eco-Drives. These solar-charging bezels look completely normal - you wouldn’t even know they are translucent - but their presence means Eco-Drives can now boast much fancier designs.

It depends on so many factors, including but not limited to the cost of the watch, the type of watch you've bought (vintage or new), and the import laws of your country. If you're unsure we recommend checking the import laws that relate to your country before ordering.
Are your watches water resistant?
Our serviced watches are typically tested to their original water resistant specifications, but we would never recommend pushing vintage or neo-vintage watches to their depth limits.
What is your returns policy?
Due to the vintage and neo-vintage nature of most of our watches, we do not offer returns under normal circumstances. All sales should be considered final.
