What’s left of the “dial” is essentially a satin-brushed, ruthenium-toned ring round the edge and both anthracite sub-dials. There’s a rehaut printed with a minute chapter ring as well. In my experience, legibility isn’t the strongest suit for a skeletonized watch, but that’s less of a problem in the case of the watch. The usage of pink gold applied hour markers and pink golden baton-shaped palms, both filled with lume, should provide sufficient legibility in most light conditions. The “Audemars Piguet” logo is printed onto the surface of the sapphire crystal on the front, and this gives it a nice floating effect.The sub-dials are simple with white printed white and text baton-shaped hands. The sub-dial at 3:00 suggests chronograph minutes and the one at 9:00 shows constant moments. One possible issue with legibility must do with the chronograph seconds hand, which is black with a lumed white tip. Between how thin the hand is and also the colour, studying the chronograph elapsed time might be more cumbersome than individuals may like. It’s hard to say for certain until we get our hands on a tangible example of the watch.I’ve left the case and bracelet description to the last because those are some of the most recognizable aspects of the watch. This is the exact same Gerald Genta layout that’s popular among several collectors however with 44mm by 13.2mm case measurements. This is a somewhat large watch with a wide bezel on both the front and back. Each of the straight lines and sharp angles also give it a larger appearance. There will be the obvious visual differences in the two substances but what I find intriguing is that titanium is generally a light material with high tensile strength, while gold is a compact but soft material. What this means is that the experience of wearing every variation should be substantially different, and that I personally find this intriguing.
First introduced as a 50-piece, green dial limited edition for Singapore retailer The Hour Glass, the Audemars Piguet Royal Oak Extra-Thin in yellow gold was added to the regular line-up at SIHH 2017. And it is as good looking and expensive as it ever was.
A modern remake of the original Royal Oak “Jumbo” ref. 5402 of 1972, the Royal Oak Extra-Thin is a classic in steel and impressive in gold. It was originally available only in pink gold, which made it loud, but the yellow gold rendition comes across as slightly more classic. Yellow gold is after all one of the metals the Royal Oak was available in, back in the 1970s.
Available in either the classic dark blue or a newly introduced yellow gold finish, the Royal Oak Extra-Thin in yellow gold is physically identical to its siblings in steel and pink gold. The case is 39mm wide, thin at 8.1mm high. It cuts an elegant profile on the wrist, and is weighty despite being slim.
Because the case is essentially an agglomeration of flat surfaces, it feels somewhat angular on the wrist unlike its only peer, the Patek Philippe Nautilus, which is comprised more rounded shapes.
Yellow gold is not common in high-end men’s watches, especially from haute horlogerie names, but it’s an appeal look for someone who leans towards a lavish, slightly vintage feel. But like all other gold alloys, yellow gold is soft (marginally softer than white gold in fact), leaving the lovingly finished surfaces of the watch vulnerable to marring. There is perhaps no other watch that looks as good as the Royal Oak when factory fresh and pristine – the alternating polished and brushed surfaces on the case are gorgeous.
Both the blue and gilded dials have the same quintessential chequerboard tapisserie guilloche that’s a trademark of the Royal Oak. Done by hand on a rose engine – creating the telltale motif below the chequerboard – the dials are brass but fitted with solid gold hands and hour markers. Both colours are equally handsome, but the yellow gold finish has an edge in that it’s a less common colour that’s unashamedly loud while maintaining a modicum of style.
Mechanically the Royal Oak Extra-Thin is almost identical to the 1972 original, with the same calibre 2121 that was originally developed by Jaeger-LeCoultre as the calibre 920. A sophisticated and slim movement that’s withstood the test of time, the calibre 2121 has been slightly upgraded over the years, improving its robustness and reliability, but still lacks a quickset date – probably the singular weakness of the Royal Oak Extra-Thin.
Notably Audemars Piguet now owns the intellectual property for the calibre 2121 and produces the movement in-house. Because its slimness makes the 2121 more challenging than a run of the mill calibre, the movement is produced at Renaud & Papi, the complications specialist owned by Audemars Piguet better known for the tourbillon movements it produces for Richard Mille.
Like the calibre 2121 found in other Audemars Piguet watches, the movement inside the Extra-Thin can be customised with a personalised rotor that can be open-worked to form a variety of motifs.
