Carbon & Titanium SRPJ45K1

Custom Seiko Diver — SRPJ45K1 Dial with Titanium & Forged Carbon Upgrades

This custom-built Seiko diver is where engineering meets artistry. At its core is the translucent SRPJ45K1 dial, which offers a unique view of the kanji date wheel beneath—a subtle nod to Japanese craftsmanship and tradition.

The case is ultra-lightweight titanium, giving the watch a rugged yet refined feel, while the bezel insert is made from forged carbon, providing both visual texture and exceptional durability. Skeleton hands add an extra layer of depth, complementing the open dial for a look that's as technical as it is striking.

Fitted with a vivid orange rubber strap for a splash of character, this piece blends playful design with high-spec materials—perfect for collectors who appreciate bold mods with a purpose.
