✅ Seiko NH35A Movement
The Seiknaut Black is a modern icon - bold, lightweight, and built for those who want their wristwear to make a statement. This custom Seiko mod features a stealthy matte black dial and sporty silhouette that feels as sleek as it looks.
At its core is the reliable NH35A automatic movement, complete with 24 jewels, a calendar function, and hacking feature for daily precision. The brushed stainless steel case measures a striking 43.5mm, yet wears comfortably thanks to its slim 11.2mm profile and lightweight construction. Flip it over to reveal a sapphire exhibition case back, giving you a clear view of the movement inside.
Paired with a durable black silicone rubber strap and butterfly clasp, the Seikonaut Black is a go-anywhere, do-anything timepiece with modern edge and mechanical soul.
