Patek Philippe World Time Moon 5575G: The 175th Anniversary Unboxing
Patek Philippe built the reference 5575G to mark its 175th anniversary, and the presentation matches the occasion. This is the World Time Moon in 18k white gold, one of the pieces the company released in 2014 to celebrate 1839 to 2014. We unboxed one at Watches Off 5th, and from the outer box to the star-map dial, it reads like a celebration first and a watch second. Here is what came out of the box and why this reference still gets attention from collectors.

The Presentation
The packaging tells you this was never meant to be an ordinary release. It arrives inside an outer box carrying the 175 anniversary logo, and inside that sits a lacquered wood presentation box. You also get a commemorative medallion, a signed certificate, and a hardcover booklet. It is the kind of full set that matters when one of these changes hands, and a complete 5575G is worth more for it.
The outer box carries the 175 anniversary logo.
A lacquered wood box holds the watch, with the anniversary logo on the lid.
The commemorative medallion shows four generations of the Stern family and the 1839 to 2014 dates.
The Dial: World Time and the Night Sky
The black dial is where the reference earns its name. A fixed ring of 24 world cities runs around the outside for the world time reading. Just inside it, a 24-hour ring turns to track day and night, marked by a small gold sun and a gold crescent moon. The center is a star-studded sky chart with a moon-phase display at the base. It was the first Patek Philippe World Time to carry a moon phase, and the two functions sit together without crowding each other.
The 24-city world time ring surrounds a central sky chart with the Patek Philippe signature.

Case, Movement, and Caseback
The case measures 39.8 mm in 18k white gold, with a rounded bezel and curved lugs. It stays slim, a little over 10 mm thick, with a lug-to-lug of roughly 48 mm. Inside runs the in-house caliber 240 HU LU, a self-winding movement built on Patek's ultra-thin micro-rotor, with a 48-hour power reserve. The caseback is solid white gold, engraved "Patek Philippe Geneve, 175e Anniversaire, 1839 – 2014." It is a fitting close to an anniversary piece.
The solid caseback reads 175e Anniversaire, 1839 to 2014.
From the side you can see how slim the case stays, with a fluted white gold crown.
On the Wrist
At 39.8 mm and just over 10 mm thick, the 5575G wears easily. The curved lugs pull the case down onto the wrist, so it has presence without feeling heavy or oversized. It comes on a black alligator strap with a white gold Calatrava-cross prong buckle, itself engraved with the 1839 to 2014 dates. This is a dress watch you can actually wear, and the black dial keeps a busy layout looking calm.
The 39.8 mm case wears comfortably thanks to the curved lugs.
The Calatrava-cross prong buckle carries the anniversary dates too.
Rarity and the Secondary Market
Patek made 1,300 pieces of the 5575G, all in white gold, and only for the 175th anniversary. It has been discontinued for years, so every example now trades on the secondary market. Between the limited run, the full anniversary set, and a complication mix Patek had not put together before, we see steady interest in this reference whenever a clean one turns up. What any single piece brings depends on condition and whether the box and papers are complete, and we are speaking from what we see in the market rather than giving financial advice.

What makes the World Time Moon special?
