Grand Yacht Blue – Seiko Mods

The meticulously crafted timepiece boasts a robust 42mm case diameter and a thickness of 16mm, accommodating both the case back and a double-domed sapphire crystal that enhances readability under various lighting conditions due to its anti-reflective properties. The horn-to-horn measurement is a comfortable 46.5mm, ensuring a balanced fit on the wrist, while the 22mm lug width accommodates a range of strap options.

Constructed from high-quality 316L stainless steel, the case is engineered for durability and a sophisticated look. Its caseback features a clear sapphire panel that offers a glimpse into the inner workings of the watch. The crown, also crafted from 316L stainless steel, is securely screwed to ensure water resistance and protect the internal components.

The strap, matching the material of the case and crown, is also made from 316L stainless steel and can be adjusted from 15 to 21 cm in length, providing versatility and comfort for various wrist sizes.

Displaying the time is a dial inspired by the Seiko SPB187, featuring indices and hands coated in Lumibrite green for excellent visibility in low-light conditions. The bezel is made from the same resilient stainless steel, designed to rotate unidirectionally, adding functionality and style to this exquisite timepiece.
