Patek published the Nautilus 5711, available in steel and rose gold, in 2006 to celebrate the collection’s 30th anniversary. As an all-stainless steel model with time and date windows, Nautilus 5711/1a is the closest contemporary to the original reference. It is also the most popular model of the nautilus, often considered the hottest cheap luxury watch on the market today.
To get your hands on a Nautilus ref. 5711/1A needs either waiting for years for one to become available at an authorized retailer or a willingness to pay more than double the retail price in the secondary market. For fans of pink valuable metal, there’s the full rose gold version, the Nautilus 5711/1R too. 
The Nautilus 5711 features a 40mm case (around 8.3mm thick) that is water-resistant to 120 meters. In real Nautilus fashion, the ref. 5711 is paired with an integrated bracelet, equipped with a fold-over clasp. The steel 5711/1A comes with an option of a blue dial or a white dial while the rose gold 5711/1R consists of a chocolate brown dial, all complete with horizontal embossing.
Patek also launched the Nautilus 5712 in 2006, which consists of a moonphase display, running seconds sub-dial, date display, and power reserve indicator. Similar to the 5711, the Nautilus Moonphase sports a 40mm case. However, Patek makes the ref. 5712 in three metal options – steel, rose gold, and white gold. Besides, while the steel Nautilus 5712/1A has a steel integrated bracelet, the rose gold 5712R and white gold 5712G have leather straps.
Inside the Nautilus Moonphase 5712 is the in-house Caliber 240 PS IRM C LU automatic movement, visible through the exhibition caseback, with a power reserve rating of 38 to 48 hours. The water resistance rating of the more sophisticated 5712 is half that of the simpler 5711 at 60 meters.
In 2010, Patek expanded its flagship sports watch collection by adding the Nautilus Annual Calendar ref. 5726. replica Patek Philippe developed and introduced an annual calendar complication in 1996 that adjusts the time and correct display of the calendar by automatically considering whether a month is 30 days or 31 days. The only time a calendar watch needs to be manually adjusted is March 1.
The 5726 is the first Nautilus watch to this practical Patek complex. In addition to the moonphase display and 24-hour display, the dial includes a window for the date, date, and month. Although the 40.5mm case is made of stainless steel, there are some variations in the color of the dial and the material of the strap. In the middle of the nautilus’s calendar was a Calibre of 324 S QA LU 24H, a reserve of 35 to 45 hours of power, and a water-proof depth of 120 meters.

All the watches come with interesting stories. And working with pre-owned watches, we hear quite some of them at Crown & Caliber. The journey a watch takes before it gets to us has many twists and turns, and maybe even an unexpected name attached.
The watch in question was a replica Patek Philippe Calatrava. We were disappointed at the very first beginning. There was an engraving on the case back that we hadn’t known was there. This meant we would possibly have to remove it or sell it as-is, which could hurt the resale value. 
One of our watchmakers looked over the watch and decided that the engraving was in fact done in the Patek Philippe factory. It was fine and delicate, reading, “Patek Philippe Pour Gobbi 150 Ans 1842-1992,” simply translated to “Patek Philippe for Gobbi 150 Years.” This could only be a reference to Gobbi Milano, the luxury fake watch retailer in Milan, Italy. The Gobbi name is associated with the highest quality of service along with one of the finest selections of high-end watches anywhere in the world.
Knowing we had a special timepiece on our hands, we dug further into the boutique’s history. Raimondo Gobbi opened the very first shop in 1842, and it’s been family-owned ever since. Its first services related to pocket watches and pendulum clocks. Ten years later, Raimondo Gobbi became the “Clockmaker of the Royal Court”. This distinction planted the roots for a prestigious factory. In the 1930s, Gobbi added jewelry to its already-stellar range of luxury Swiss watches. The original establishment was damaged during WWII. But, the Gobbi family opened a new boutique in 1949 in Milan, where it stands today.
Through years of satisfactory service and selling fine time pieces, the Gobbi name has obviously become one of legacy and luxury in today’s market. Present-day brands available at Gobbi include Patek Philippe, Rolex, Tudor, together with Gobbi’s jewelry collections.
Something made the watch different. First, it was the third example of this cheap replica watch in pink gold sold at public auction. Second, it was only the second known example of that reference in rose gold with a blue enamel dial. Therefore, the Gobbi Milano signature made this watch the rarest of the rare and certainly helped it sell for a high number.
The Gobbi signature clearly holds a special value. And for the typical watch we sold, the Gobbi engraving made a run-of-the-mill Calatrava into something really special. It’s interesting to run across an unexpected detail like that every now and then.

Things are sophisticated this week,beginning with the perpetual calendar, which is represented here by a yellow gold Patek Philippe replica. You will find some chronographs with very unusual features as well, consisting of a LeCoultre with a rotating slide rule bezel and an Orvis Solunagraph with a tide indicator.
Fake Patek Philipp with Perpetual Calendar Complication
Patek Philippe replica is well-known for introducing the first series-produced perpetual calendar wristwatch, back in 1941. It depended on the automatic caliber 27-460, to which a perpetual calendar mechanism was fitted, becoming the caliber 27-460Q. It was eventually replaced by the reference 3450 in 1981, which added a leap year indication. 
The current watch is cased in yellow gold, as are the huge majority of the 586 3448s made. Its 37mm diameter makes it wear large on the wrist, and represent a radical design change from the previous, smaller perpetual calendar replica watches from Patek. The case shows signs of some light previous polishing, but the hallmarks are still visible, even though a bit faint (the clarity of the hallmarks is always a good thing to check when examining precious metal cases). The dial belongs to the third series produced from 1971 to 1978 and showed perle minute divisions, and a considerably large date ring. This time period is consistent with the Sigma symbols found at the bottom of the dial, while the extract from Patek’s archives provided with the watch, would allow us to narrow down the manufacturing date even more.
TAG Heuer Diver Professional Watch of the The ‘Nightdiver’
I have already shared my best favor with the (TAG) Heuer Diver Professional, and especially for the luminous dial version. So you would not be astonished to see the fake watch shown here, even though it has a much bigger diameter, at 41.5mm. Its crown placement at 4 o’clock is like that of the 1,000m water-resistant divers from Heuer, originally in quartz. With its automatic caliber 2.89 (a rebadged ETA movement) this watch was released later – in the late 1980s – and therefore only comes with the TAG Heuer signature.
The watch here comes with its original Jubilee strap, and the clasp offers a diver’s extension. The dial still shows some luminosity, and displays a bit of aging, but nothing too severe. The automatic caliber is said to be working well, but the rotating bezel does not have any deep scratches.
