(January 2023 at our store)
Due to the nature of the material, it cannot be overfinished, so although small scratches remain on the back cover, there are no major dents. Coating scratches on the glass are also only not affected by visibility. The genuine strap has been cleaned at our store.

- Model Information
- The "Ocean Collection" is designed and manufactured based on the elegant design expected of a top jeweler. Project Z4, the fourth model released in 2007, features two dials that display hours and minutes to indicate two different time zones. Day and night are displayed according to each time zone, allowing you to distinguish the time in two different locations at a glance. The case material is made of "Zalium," an alloy of aluminum and zirconium used only in the aerospace industry, which is harder and more corrosion-resistant than titanium. Limited to 300 pieces worldwide.
