Why are Rolex watches sought after?

Rolex watches are the most famous and popular among all Swiss watch brands for men. An estimated 800,000 to 1,000,000 of these are made each year. However, these watches are in high demand, particularly the high-end varieties such as the Cosmograph Daytona and the Rolex Submariner.

Rolex watches are renowned for their beauty, mechanical precision, and reputation for quality and reliability. Rolex watches have various styles that can meet almost every need. Women's Rolex watches are elegant and refined. These watches can match most outfits and work well with a variety of other jewelry.  Men's Rolex watches provide a sleek sense of style and ruggedness. Though Rolex watches look good with business attire, they also look fantastic with casual clothing.

Why do used Rolex watches bring more value to the buyer?

Many Rolex releases are in demand because supplies for some styles are limited. With some notable exceptions, used Rolex watches are usually more affordable than new ones. Even when used, Rolex watches are durable and reliable and are typically available at the same level of quality as buying a brand new one. Moreover, the quality of materials put in each Rolex watch by themselves is extremely valuable. For example, the diamonds in Rolex watches are worth a lot on their own.  

Some pre-owned Rolex watches fetch a higher value in the used watch market than new ones. Some used Rolex Daytona watches, for instance, are highly-sought-after. 

What makes an Audemars Piguet watch very special?

Audemars Piguet watches are comparatively rare. Only 40,000 watches are produced annually. 

The upfront price for an Audemars Piguet watch is generally higher than a Rolex and is considered among the "Big 3" by watch enthusiasts, whereas Rolex is not.

Audemars Piguet watches have more detailed finishing than most other luxury watch brands. Both for the mechanical components and the casing itself. The level of complications for Audemars Piguet watches is generally higher than in most luxury watch brands.

How can I find an affordable and genuine Patek Philippe watch?

Even if you buy pre-owned, you can get the most value from a Patek Philippe watch. Genuine Patek Philippe watches are very durable, resistant to damage, and can retain their quality for a long time.

Diamond Source NYC can help you determine if a Patek Philippe watch is genuine.

All the new and pre-owned Patek Philippe watches you will find in our store are genuine and we guarantee their authenticity. The quality of their internal parts and workmanship make these watches difficult to copy.

Why do Patek Philippe watches hold their value well?

With just under 1 million Patek Philippe watches developed and produced since the company was founded in 1839, the supply of Patek Philippe wristwatches is scarce.

Each watch is handcrafted with the level of quality and traditional approach to manufacturing that Patek Philippe is renowned for. Each timepiece takes months to produce, with some models taking up to 9 months.

Patek Phillippe watches have complications and an annual calendar. 

Discontinued models are highly sought after by collectors and can reach more than ten times their original retail price.

The waitlist for some models, such as the Aquanaut, is very long. It will take months before you can get your hands on one.

How can I spot if a Patek Philippe watch is fake?

Many forgers craft fakes better than others, and fake Patek Philippe watches are no exception. Here are five of the ways you can spot a fake Patek Philippe watch:

- The serial number should be inside the case back. Patek Philippe rarely etches the serial number of their watches on the outside surface of their case backs.

- Check for tiny imperfections in the metal of the questionable watch. Patek Philippe is meticulous about selecting the materials they use to make their wristwatches.

- Patek Philippe watches are comparatively heavier than watches of the same size. The reason is because of the higher-quality materials Patek Philippe chooses to use in the internal mechanism and the case of the watches they produce.

- Unlike most luxury watch brands, Patek Philippe screws don't have a blue hue.

- Check the crown and dial for the following clues:

- The crown details in all Patek Philippe watches are etched to perfection. That is, the crown is detailed and not mottled.

- The lugs around the 6 o’clock mark contain a small single diamond setting between those lugs.

- Though challenging to spot, the font used for the lettering on genuine Patek Philippe watches is distinct and is a particular size. 

- Genuine Patek Philippe watches always come with a certificate of authenticity. An experienced jeweler or watch expert knows what a real certificate of authenticity looks like and can spot minor signs that the certificate is fake.

- The prices of fake Patek Philippe watches are too good to be true. Always check with us or on a reputable collector’s website. If the price point is less than half of those values, the watch is most likely fake.

Diamond Source NYC’s experts can spot fakes from any luxury watch brand. However, watch forgers are getting more skillful and have been known for pulling off details that hide most signs of forgery. Rest assured that any watches that you buy from Diamond Source NYC are certified genuine.
