Audemars Piguet Royal Oak 15400ST Full Black Ceramic – Review

1. Overview

This execution of the Royal Oak 15400ST is fully crafted in black ceramic (or DLC/PVD-coated steel), capturing the iconic Royal Oak silhouette entirely in black. The 41 mm diameter and integrated bracelet remain true to Gérald Genta’s original design, while the dramatic monochrome finish modernizes its aesthetic.

2. Case & Bracelet

• Material: Black ceramic or PVD-coated steel finish—highly scratch-resistant, lightweight for its size, and strikingly stealthy.

• Dimensions: 41 mm across, around 9.8 mm thick (mirroring the steel 15400), with slimmer lugs and a refined mid-case.

• Bracelet: Full integrated black finish—matte and polished facets catch light dynamically, complementing the sporty yet refined look.

3. Dial & Hands

• Dial: Tapisserie guilloché pattern, similarly blacked-out for a “stealth” effect, with applied hour markers and hands offering strong contrast and legibility.

• Markers: Polished white gold baton indices and hands with luminescence ensure readability despite the dark palette.

4. Movement – Calibre 3120

• Type: In-house automatic

• VPH: 21,600

• Power Reserve: ~60 hours

• The same robust and refined AP 3120 caliber that powered the steel Royal Oak 15400.

Despite its full-ceramic finish, the watch remains lighter than steel and retains excellent comfort thanks to the bracelet’s articulate construction. The 41 mm case size wears true, with a thin profile beneath a cuff.
