# Reference: **Model:** 8730 Eco-Drive with Moon Phase and Triple Calendar **Year Produced:** August 2022 **Timestamp:**  [https://imgur.com/a/rwaLnDw](https://imgur.com/a/rwaLnDw) **Album:**  [https://imgur.com/a/tv2SWxv](https://imgur.com/a/tv2SWxv) # Features: **Dial.** The name of the watch, Tenmanboshi (天満星), roughly translates to “The Heavens Brimming with Stars”, which explains the thick belt of gold leaf suspended in the black-as-night, urushi lacquer subdial. The contrast between the two is magical. Each arrangement is done by hand, ensuring no two urushi sub-dials are alike. **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. As much as I love their cosmological dials and features, the thing that continues to draw me into Campanolas is their three dimensional 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 fully charged from only 19 hours of sunlight. Previously, Eco-Drive dials had to be translucent 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.  **Design Improvements.** As solar charging technology improved, the size of the capacitors shrank. This innovation led to the creation of Campanola Eco-Drives, featuring translucent bezels. Interestingly, these bezels look completely normal - you wouldn’t even know they are “translucent” - but their presence means Eco-Drives can now boast much more intricate designs. The BU0020-3A is a wonderful example of this.  # Details: **Condition**: In very good condition, with small hairlines on the bezel and case.
