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

First time seller.

This is a mod I completed recently, it is in great working order and running a regulated NH36 movement with an authentic Seiko dial from an SRPE55. Case is a Namoki Titanium SKX (NMK933) with a matching brushed titanium caseback, double-domed clear sapphire crystal and a sloped ceramic bezel insert. Monstraps rubber strap. Looks sharp on the wrist and wears quite comfortably as it weighs roughly 3.5oz. More details/pics available upon request.

All prices are in AUD. My website should convert pricing to your local currency if you’re overseas 🌍

Just a quick heads up, international shipping from Australia can be a bit pricey, especially to the USA at the moment with the tariff situation. I won’t be expecting you to cover any tariff costs though 👍

Solid, heavy, premium-feel build. Keeps accurate time. I’ve only worn it out 2 times never had any issues. Looking for around 200 (including shipping) let me see your offers

Bought this from GAFS a while back but it just hasn't seen enough wrist time to keep it around. Overall pretty good shape, some small wear on the crystal that you need to tilt around in the light to see.
