Deep blue under brushed steel.

An ABA London custom build. A sapphire-blue textured dial set in a brushed steel case — the CasiOak at its most classically luxurious. From Vault Drop 001.

On the wrist. The textured blue dial shifts with the light beneath the octagonal steel bezel, polished markers picking out the hours, on a black strap that keeps the piece grounded. Curated and finished by hand in our London studio.

The detail

  • Authentic Casio module. The genuine CasiOak movement — shock-resistant, with world time, stopwatch and full auto-calendar.
  • Textured blue dial. The patterned surface catches and turns the light — the nod to haute-horlogerie dials that gives the piece its name.
  • Steel on blue. The pairing every serious collection reaches for, delivered in the CasiOak's octagonal frame.

Every ABA custom is assembled and checked by hand across all eight stages before it's boxed. See the full process → A full inspection record is available on request.

Ownership & assurance

  • Hand-built & individually inspected in our London studio — minor tonal or alignment variation is the signature of workshop assembly, not a fault.
  • Tracked & fully insured dispatch — UK delivery typically 1–3 working days (dispatched within 1–2 business days).
  • 3-month ABA Warranty on the movement and functionality (cosmetic and aftermarket components excluded).
  • Final-sale custom build — as a bespoke commission it isn't eligible for a change-of-mind return, but you're fully covered if it arrives significantly not as described under UK consumer law.
  • Responsive aftercare — direct support that doesn't end at delivery.
How do I know my watch is 100% authentic?

Because we have it, and we checked it. Every piece passes our 8-Stage Bench Verification before dispatch — movement calibration, authentication against verified references, hands alignment, provenance and fitment, lume, power reserve, multi-angle inspection and final sign-off, each signed off by hand at our London bench. Read the full process here. Every order ships with its documented Authentication Sheet.

What exactly am I buying — is it new?

No, and we won't pretend otherwise. Our branded watches are genuine ex-retail stock: authentic product that is not sold as new. Our ABA Custom builds are genuine Casio bases, hand-modified in London. Condition is described honestly on every listing — if anything is unclear, ask us before you buy.

What if it's not right for me?

Return it within 30 days (UK) or 14 days (international), unworn and complete with all original paperwork and packaging, and we'll refund you. That applies to custom builds too — we don't think your flagship purchase should be the one with the small print. Not sure on sizing? Tell us your wrist measurement at checkout and we'll adjust the bracelet before dispatch, free.

When will it arrive, and is it protected in transit?

Order by 12 PM and your watch is dispatched the same day — Royal Mail 24 within the UK (free UK delivery), DPD Air Express internationally. Every parcel is fully insured and tracked door to door.

What aftercare do I get?

Every watch is covered by the 3-month ABA Warranty against mechanical fault under normal use — if something fails, return it, we inspect it and we replace it. Direct support from our team before and after delivery, and your statutory rights are unaffected. Full details here.
