This Audemars Piguet Royal Oak Dual Time 26120STis an unusual combination of the iconic Royal Oak design and a seldom seen complication. Itremains one of the few Royal Oak references to house this practical complication, which undoubtedly proves itself useful on a daily basis.

A Dual Time Royal Oak

Shortly after the originalRoyal Oak 5402, Audemars Piguet experimented with integrating a range of complications within its iconic, angular case. From the mighty to a range of chronographs, they repurposed the design to fit a wide range of functions, catering to consumers evolving tastes and appetite for variety.Having first developed the dual time functionality for an earlier reference,Audemars Piguetdecidedto marrythis practicalcomplication with their increasingly popularRoyal Oaksilhouette in 1992.However, it was confined to a for quite a while, as this size was favoured by a wider range ofclients at the time.

However, Audemars Piguet eventually integrated the complication into their Jumbo Royal Oakcase, with this reference, the 26120. Classically sized, at 39mm in diameter, it resembles the original proportions of the ref. 5402, within a more contemporary design. Featuring a date, dual-time and power reserve functionality, the model was discontinued around 2015. Bearing some resemblance to the dial layout of Patek Philippe's Nautilus 5712, it retains legibility and balance, despite the wealth of information displayed.

The Design

The dial of thisRoyal Oak 26120STis rendered in ashiny blackcolour, which wonderfully complementsthe stainless steel case and bracelet. Not typically used within theRoyal Oakfamily,the black dial is deep and legible, enhancing the varied reflections and textures of the case.The dialintegrates a range of different finishing techniques, with the lightly recessed subdials standing out against the "Grande Tapisserie" pattern.

The different complications are displayed throughout, withthe date function at 2 o'clock, thesecond timezone at 6 o'clock, and the power reserve indication at 9 o'clock. A day and night indicator is also conveniently included, overlapping with the second timezone sub-dial.Subtle red accents are included throughout, bringing a welcome touch of colour to the design.The "Audemars Piguet" signature is discretely nestled at the top of the dial.The white gold applied hour-markers and the distinctiveRoyal Oakhands are filled with luminescent material, for added legibility.

The case and bracelet are excellently finished, with angular, bevelled and polished edges throughout. The polished screws, bezel and case edges contrast with the brushed surface of the case and bracelet, creating a distinctive effect on the wrist. At 39mm in diameter, and only 10.3mm thick, the case proportions remain relatively restrained, despite the additional complications. In fact, it is only around 3mm thicker than the Royal Oak 15202, one of the brand's most sought-after modern offerings.
