Patek Philippe’s headline launches this year included the surprising Celestial ref. 6105G and Nautilus 50th anniversary editions, but also more classical, yet under-the-radar, watches, like the Calatrava ref. 5227G-015 with a “rose-gilt” dial and hinged case back.

Though the Calatrava ref. 5227 with its distinctive “officer’s case” has been in the catalogue for well over a decade, the latest iteration is the best yet. The combination is somewhat formulaic – “salmon” dial and white gold case – but it is good looking and evocative of old-school Patek Philippe dress watches. At the same time, this new variant of the ref. 5227 contains a latest-generation automatic movement.

Ironically two of the standout launches by Patek Philippe during Watches & Wonders were fairly basic, essentially facelifts of references that have been in the catalogue for decades. One was the ref. 5396R-016 Annual Calendar, and the other is this, the Calatrava ref. 5227G-015.

Though both are entirely different in function and price, they are similar in style. The designs are both restrained and evocative of vintage Patek Philippe watches; both also have dials in popular shades. “Salmon” is definitely overdone as a dial colour, but it doesn’t stop this Calatrava from being really appealing.

The ref. 5227 is typical Patek Philippe in form. Even though it’s at the larger end of the range for Calatrava models, it still feels elegant. The case is thin and sits flat on the wrist. The “rose-gilt” dial gives it more presence than earlier versions of the model, which were conservative and a little boring.

As is sometimes the case with such watches, the date window gets in the way of a good design. It could have been alleviated with perhaps a tone-on-tone date, but alas not.

Still, the watch is appealing, and for more than just for the dial. The hinged case back is an unusual feature for an entry-level-ish model. The hinged back is done well enough that the case remains thin while the hinge itself is neatly concealed when the back is closed. That, combined with the elegantly concave lugs, gives the case surprising details.

The ref. 5227G is an entry-level Patek Philippe and amongst the most affordable Calatrava models with a gold case. However, it still costs US$47,262, which feels steep despite the appeal. The watch is clearly top quality industrial high horology, but a chunk of the price is still the value of the brand.

On the outside, the ref. 5227G-015 is essentially the same as the first variant that was launched in 2013. Even though it’s identical on the wrist in terms of size and feel, the latest version of the ref. 5227G looks very different. The dial gives it more punch and a little more modernity. It’s a dress watch that doesn’t feel stuffy.

The “officer’s case” is unchanged, but still good enough even 13 years on. It’s elegant with good proportions, despite having an extra layer in the form of the hinged back.

As expected for a Patek Philippe, the case is finely constructed. Even though it is thin, the case is solidly put together. This holds true for the hinged back as well, which is connected to the case with a robust looking hinge that is nonetheless almost invisible from the outside.

The only downside of the hinged back is the integration of the hinge into the case middle, which is visible when the back is lifted. Four visible screws anchor it firmly to the case middle, but this disrupts the otherwise clean appearance of the back.

Officially described as “opaline rose-gilt”, the dial is a pinky hue on a brass base – “salmon” in other words. It has a smooth, finely grained surface. The hour hands and applied elements are all 18k white gold, but coated black. The quality of the dial and its fixtures is high, but the execution is relatively simple.

The dial design is no frills and made up of elements long found in Calatrava models. Here it’s slightly modernised with the railway minute track and restyled dauphine hands, but still recognisably Calatrava. The only bit that feels out of place is the white date disc.

Even though most of the exterior components are unchanged, the movement inside has come a long way since the original ref. 5227 of 2013. While the original generation was powered by the cal. 324 S C, this is equipped with the cal. 26-330 S C.

The cal. 26-330 S C is evolved from the cal. 324 S C, but notably more advanced; it is arguably a 21st century movement, while the cal. 324 S C was still a 1990s calibre at heart. The cal. 26-330 S C is advanced enough that it is likely the final frontier for this movement construction; its replacement will be an entirely new calibre.

Amongst the obvious upgrades are a silicon hairspring, which is more tech than artistry, but still offers practical upsides for the wearer in terms of magnetism resistance, and the manufacturer in terms of efficiency.

But the cal. 26-330 S C is a thorough reworking of its predecessor, so it gains upgrades in almost every aspect. Another upgrade is the sprung teeth for the indirect centre seconds that eliminate play between the wheels, while yet another is the sprung pawl with an integrated jewel for the unidirectional winding mechanism.

Notably, the decoration of the cal. 26-330 S C is also better than that of the cal. 324 S C from a decade ago, illustrating the advances Patek Philippe has made across its movements. The cal. 26-330 S C is clearly industrial haute horlogerie, but is is as good as it gets in this genre.
