2. About the Watch

This custom Seiko Datejust-style mod combines a deep black dial with diamond-style indices and a striking two-tone steel and gold finish for a bold luxury look. The gold fluted bezel, matching gold centre links on the Jubilee-style bracelet and cyclops date at 3 o'clock deliver classic Swiss-inspired aesthetics with modern Seiko reliability.

3. Specifications
