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

Having first developed the dual-time functionality for an earlier reference, Audemars Piguet decided to marry this practical complication with their increasingly popular Royal Oak silhouette in 1992. That being said, it was confined to a 36mm case for quite a while, as this size was favoured by a wider range of clients at the time.

Audemars Piguet eventually integrated the complication into their Jumbo Royal Oak case, with this reference, the 26120. Classically sized, at 39mm in diameter, the watch resembles the original proportions of the reference 5402, within a more contemporary design. Featuring a date, dual-time complication, 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.

Not typically used within the Royal Oak family, the black dial on this reference 26120ST is deep and legible, integrating a range of different finishing techniques, including the Grand Tapisserie pattern. The different complications are displayed throughout, with the date function at 2 o'clock, the second time zone 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 time-zone sub-dial. Subtle red accents are included throughout, bringing a welcome touch of colour to the design.

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.
