Built to order. Typically dispatched in 7 working days.

The Octagon 41 opens ABA Custom, our made-to-order line of Seiko-movement builds. Each piece is specified by us and assembled against that specification once you order — nothing sits in a box waiting for a buyer. That is why it takes about a week rather than a day.

The classic black colourway is the one we would point a first-time buyer at. A dense, textured dial that reads near-charcoal in daylight and full black indoors, applied indices, and a brushed steel case with polished chamfers running the length of the integrated bracelet.

Specification

41mm 316L stainless steel case, integrated bracelet, butterfly clasp
Seiko NH35 automatic movement, made in Japan by TMI
Sapphire crystal, anti-reflective coating
Exhibition caseback
5ATM water resistance
Textured black dial, applied indices, luminous hands, date at 3

What this is, plainly

This is a custom-built watch running a genuine Seiko automatic movement in an aftermarket case of our chosen design. The dial carries Seiko branding. It is not a Seiko factory product, and it is not a product of any luxury manufacture — it carries no third-party maker's name, marks or model designations, and we claim no association with any of them.

We put this on every ABA Custom listing. We would rather you buy with your eyes open than be surprised when the parcel lands.
