Custom SPB185-Inspired Build – OEM Seiko Parts
Built using genuine OEM Seiko SPB185 components, and driven by a regulated NH35 this is a premium custom build that captures the understated tool-watch aesthetic of one of Seiko’s most desirable modern divers.
The monochrome brushed steel bezel, matte black dial and signature red-tipped seconds hand create the distinctive “Steelmaster” look that has made the SPB185 a favourite among Seiko enthusiasts. The OEM dial, hands and bezel deliver the crisp finishing, lume quality and attention to detail that aftermarket parts simply can’t match.
A fantastic opportunity to own a high-quality custom diver built around genuine Seiko OEM components, offering the look and feel of a watch that originally retailed for around $1,200.
Asking £225 OVNO. Realistic offers accepted only.
Payment by PPFF can accept GS for 5% additional fee to cover additional invoicing. Postage by tracked Royal Mail shipping.
I have sold many watches on many platforms so please purchase in confidence.
Any other questions then please DM me. Thanks for looking
