Patek Philippe Nautilus Ruby

It shouldn’t be surprising that a Patek Philippe holds the world auction record for a watch ($31.2 million for a Patek Grandmaster Chime, sold at Christie’s). Known for impeccable craftsmanship and some of the most complicated timepieces ever created, the brand is considered by many to be the height of fine watchmaking. Collectors simply love Patek Philippe watches.

The house was founded in Geneva in 1839 by Polish expats Antoni Patek and Franciszek Czapek. Czapek left the firm, and in 1845, Patek partnered with French watchmaker Jean Adrien Philippe. It was the beginning of a beautiful friendship.

Catering to the glitterati of Europe, the pair counted among their clients Tolstoy, Pope Pius IX and Queen Victoria, as well as Countess Koscowicz of Hungary, for whom they created the first Swiss-made wristwatch in 1868. They also had their eye on the American market and in 1851 entered an arrangement with Tiffany & Co. still in effect today.

During the Great Depression, brothers Jean and Charles Stern, who had previously supplied Patek Philippe with watch dials, bought the company, and it continues to be run by the Stern family today.

Under the Sterns, the house has developed some of its most famous models, including the Calatrava, an elegantly minimal dress watch introduced in 1932 and named for the Calatrava Cross (the company’s logo since 1887), and the Nautilus, the brand’s first sports watch, conceived by legendary designer Gérald Genta in 1976.

Despite the house’s longevity, it’s rumored that it has manufactured fewer than a million Patek watches, making each one all the more coveted. (The brand's pieces are understandably attractive to counterfeiters — make sure you know how to spot a fake Patek Philippe watch.)

This deep red gem is the color of heat and passion — vintage and antique ruby jewelry is perfect for those born in the middle of summer.

Rubies are one of the few gemstones that can give diamonds a run for their money. Just consider the Van Cleef & Arpels “scarf” necklace the Duke of Windsor presented to the Duchess on her 40th birthday, in 1936 — set with diamonds and dripping with rubies, a testament to the deep-red gemstone’s power — or the slippers encrusted with 4,600 rubies that Harry Winston made to commemorate The Wizard of Oz’s golden anniversary. July babies have permission to adorn themselves with this beautiful red stone even when it’s not their birthday.

Rubies are considered precious stones — along with diamonds, sapphires and emeralds — and have a hardness of 9.0 on the Mohs Scale, surpassed only by Moissanite and diamonds. They are composed of corundum, a colorless mineral that is also the basic material of sapphires. In the July birthstone, the red of the gemstone — and the various hues seen in sapphires — are produced by the presence of trace elements. In the case of a ruby, this element is chromium. Rubies range in color from vermilion to a violet red. They are also pleochroic, which means that a stone’s hue can vary depending on the direction of viewing. The most sought-after color is pigeon’s blood: pure red with a hint of blue.

Rubies that are hosted in dolomite marble are the most prized: Because the marble is low in iron, so are the rubies, resulting in a more intense color. Rubies found in basalt, which has a higher iron content, are generally darker and less intense.

When shopping for antique and vintage ruby jewelry, remember that the 4Cs of selecting the perfect diamond — color, clarity, cut and carat — also apply to rubies.

According to the Gemological Institute of America, the color of the July birthstone should be a vibrant to slightly purplish red, and the stone should be clear and inclusion-free. Accordingly, the cut should show off its color and clarity. As for the last criterion, fine rubies more than a carat in weight are rare. Often, large rubies are more expensive than diamonds of comparable weights.

Antique, vintage and luxury wristwatches have captured the hearts and minds of all manner of watch collectors as well as the watchmakers themselves — it's time you found your own.

Certain vintage watches for men and iconic watch designs for women are sought after not only because of their graceful proportions or innovative materials but also because of the illustrious histories of the houses that created them, histories that they stylishly embody.

Bulgari’s legendary Serpenti watch was on everyone’s list after the collection’s bold bracelet, which technically debuted after the timepiece, graced the wrist of actress Elizabeth Taylor. If anything, elaborately crafted timepieces — the unmistakably boxy silhouette of Cartier Tank watches, the elegant and minimal Calatrava designed by legendary Swiss house Patek Philippe — are even more effective than the shape we associate with traditional wristwatches.

Form watches — the all-encompassing moniker bestowed upon non-round watches — are making headlines and completing contemporary fashionable ensembles the world over. At the same time, both casual fans and careful collectors are drawn to the unbeatable charm of vintage styles, such as the icons designed by Omega that even James Bond can’t resist.

In the early days of watchmaking, watches were fragile enough that they necessitated protection from the elements. Now, wristwatches made of gold and steel can withstand the harshest climates — even 100 meters underwater, in the case of Rolex’s Submariner. Designer Gérald Genta, whose range of clients included Rolex, created for Audemars Piguet the first luxury sports timepiece to be made from stainless steel. First introduced in 1972, the Royal Oak was a perfect choice for blending the form and function that are now synonymous with sports watches.

Are you shopping for a wristwatch? It’s good to keep your needs as well as your specific personal style in mind: A smaller, subtle timepiece is a good fit for small wrists. When will you be wearing your new accessory? There’s a versatile model out there for everyday wear, while a rugged, feature-heavy watch is a safe bet if you’re prone to embarking on all-weather activities in the great outdoors.
