This is the Patek Philippe Ref 5205. A striking (looking, not sounding) calendar watch from the legendary Geneva watchmaker. Think mirror polish, white gold case with a smoky gradient blue dial. Annual calendar display via three apertures, complete with a moon phase at 6 o’clock. The perfect accompaniment to a black tie ensemble while still being contemporary enough to wear with jeans and a polo. And despite being exceedingly difficult to purchase new (not unlike most complicated Patek models), the Ref 5205 still trades around (if slightly above) retail on the secondary market. Not that its retail price is cheap mind you. Still, for those lucky enough to be in the market for their first complicated Patek, it’s a great option. If a sometime overlooked one. Does all that mean the Ref 5205 is a good buy, though? Let’s get into the detail and you can decide for yourself.
A (Very) Brief History Of The Patek Philippe Ref 5205
Despite its contemporary styling, the Ref 5205 is not a new watch. Patek actually debuted the reference back in 2010, with two versions, both in white gold cases. The dials were dual tone, featuring silver grey or slate grey paired with matte black. This gave them somewhat of a sportier look, which was a bit at odds with their dress watch styling. Something Patek later somewhat addressed with the now discontinued Ref 5960.
I wouldn’t say the Ref 5205 was a runaway success for Patek. Not that they were producing that many of them anyway. But it performed well enough that two rose gold versions followed in 2013. These were more classic and elegant, featuring white opaline or lacquered black dials. These have since departed the collection, to be replaced by a rose gold version with a superbly understated olive green gradient dial. The inaugural white gold models meanwhile ceased production in 2018. Replaced by the gradient blue dial version of the Ref 5205G.
At present, you can buy the earlier model, white gold Ref 5205 for around US$45,000. Depending on condition, provenance, and so on. That’s around US$20,000 less than you would pay for the later gradient blue model. All three versions of the white gold model use the same calibre. So, it’s largely the desirability of the gradient blue dial that drives the premium. That and the fact that that it’s newer.
The Patek Philippe Ref 5205
The Ref 5205 was always targeted at a younger audience. But those earlier iterations didn’t exactly land in the way Patek wanted them to. That all changed in 2018 when the gradient blue dial version came along. In some ways, this was the brand kowtowing to the popular trend at the time. Blue dials – especially gradient ones – were, and still are, red hot. The impact was instant. Almost overnight the Ref 5205 became a lot more desirable to a much wider audience.
The Case
Presented in a 40mm x 11.36mm white gold case, the Ref 5205 is also contemporary in its sizing. While not exactly slim, it still sneaks in with dress watch like proportions. And will fit under your shirt cuff with a bit of gentle encouragement. A lot of the height comes from the high polished concave bezel. The way it slopes down and away from the dial makes the dimensions of the Ref 5205 appear bigger than they are. This is in contrast to the Ref 5396 – another Patek annual calendar – which appears flatter and more compact. Sure, it’s case is smaller at 38.5mm but it’s still 11.2mm thick. Yet the models look and wear completely different.
In keeping with the formal, dress watch aesthetic, the entire case shows a high polish. This includes the distinctive, open-worked lugs with their exaggerated downward curve. This makes the watch quite shiny. Combine that with the striking blue dial and you have a real head-turner. Which is great if you like that sort of attention but not ideal if you prefer to be a little more under the radar.
The Dial
The rich gradient blue colouring of the dial is without a doubt the key highlight of the Ref 5205. The olive green version is a little more understated but that’s offset by the rose gold case. The blue sunburst pattern radiates from the center, fading to black at the periphery. Patek is well known for its gradient dials thanks to the Nautilus and other models. The Ref 5205 continues this proud tradition but also elevates it a level.
While somewhat familiar, the dial layout is also unique to the Ref 5205. Across the top half of the dial are three apertures for the annual calendar displays. Day, date and month in an easy-to-read and intuitive format. In the bottom half a subsidiary dial at 6 o’clock houses a 24-hour indicator and the moon-phase display. The central time display features dauphine-shaped hands for the hours and minutes. A long with a running seconds hand.
Unusually, on the blue dial version, the hands feature lume for night time reading. This is not the case on the rose gold version, which is styled as a more formal dress watch. This again reflects Patek’s desire to make the blue dial Ref 5205 more contemporary. Oversized applied gold baton markers denote the hours.
The Movement
Inside is the self-winding Calibre 26-330 S QA LU 24H. An upgrade on the movement that featured in the inaugural Ref 5205. It comprises 339 parts, including Patek’s patented Gyromax balance and Spiromax balance spring. The movement is visible through a sapphire caseback and is quite nice to look at. The 21k yellow gold central rotor is especially eye-catching. Oscillating at 28,000vph, it offers a max power reserve of 45 hours. Which by modern standards could do with some improving on. As you would expect, finishing is to the brand’s exacting standards. Naturally the movement proudly wears the Patek Philippe Seal.
Price & Availability
The recommended retail price of the Patek Philippe Ref 5205G is US$67,267. Getting one from your authorized retailer might prove a little tricky. Patek doesn’t make that many of them each year and they are quite sought after. As such, it might take some investment in the relationship to qualify for an allocation. (Also known as spending money on other watches you don’t necessarily want.) The rose gold version is priced the same.
There’s also the secondary market option, where prices remain more or less with retail. The model did see a surge in pricing a few years back (during the Covid boom) but has come back to reality now. For the Ref 5205G, pricing tends to range between US$65,000 – US$75,000. The upper end is typically indicative of a new (unworn) or near new example offered as a complete set.
There is one important look-out though, that inexperienced buyers might miss. The Ref 5205G has been in the collection since 2018, however, it has been upgraded during that time. Original models feature the 324 S QA LU 24H/206 calibre. While the latest version features the Calibre 26-330 S QA LU 24H. Practically speaking there’s not much difference between the two. However, if you see one advertised at the lower end of the price range, this is one of the first things I would check. It won’t impact your wearing experience but it may effect future resale.
Is The Patek Philippe Ref 5205 A Good Buy?
The Ref 5205 has been around for over a decade. Its price on the secondary market went through some serious fluctuation before settling back towards retail over the past year or so. A big part of that was almost certainly due to the red hot market for watches we saw during and post-Covid. And even though it’s still in the current catalogue, getting one at retail remains a challenge. I mean come on, it’s a seriously good looking watch. Admittedly not the most complicated from Patek. Nor the flashiest. But still, a very solid piece to add to any collection.
Whether this model appreciates further over time is anyone’s guess. I would wager if Patek discontinues it you might see a little spike. But again, there’s a lot more choice in the collection now then there was when the Ref 5205 first came into the line up. Not to mention to the general competition at this price point. That said, if you could pick up a slightly older example, preferably as a complete set, with the original movement and priced below US$65,000? I would call that a good buy.
