โ Buyer's comment
When I first picked up this SBDC221, I was captivated by its beauty, which seemed to capture the ocean of Okinawa. The radiating blue dial changes the depth of the sea and the sparkle of light depending on the viewing angle, making it truly attractive. The combination with the gray bezel is exquisite, creating a sporty yet sophisticated atmosphere. The newly developed clasp can be adjusted to 6 levels, making it comfortable not only for diving but also for everyday use. The power reserve of about 72 hours is also reliable, and I'm happy to be able to use it right away on Monday even if I take it off over the weekend. The premium feeling of being limited to 4,000 pieces worldwide will also satisfy your desire to own one. by Fujimuro
