How can you upgrade a watch that is already a horological masterpiece? Set them with diamonds! This by itself is a form of art, as nothing is so complicated as setting a three dimensional, functional, object like a watch with diamonds. It often takes weeks, if not months, to make them, not only the movement but also to complete the diamond setting. The result is spectacular! Meet the world's most exclusive and expensive diamond set watches!

Few places in the world can rival with jewelry shopping in the Big Apple. New York City not only houses the boutiques from some of the most esteemed names in Haute Joaillerie from the continent but is also home to America's own major league of jewelers. Their popularity has made it that they even have been included in pop-culture, such as in Marilyn Monroe's "Diamonds Are A Girls Best Friend" or the iconic movie "Breakfast At Tiffany's." When you find yourself shopping for jewelry in New York City, make sure to include the following places:

It seems somewhat of a contradiction, as such an esteemed and respected name in diamond trading, to have watches in your collection that are not set with precious stones. In fact, it illustrates how far Graff has come, as their watches are now generally accepted as masterpieces, even without diamonds.

Smaller and thinner watches seem to be the trend again lately, but sometimes you just need a larger watch. Not only because you enjoy wearing something substantial on your wrist, but also because this provides the room to fit it with the most extraordinary complications!

Ladies watches have always played an important role in the Grand Prix D'Horlogerie de Geneve, or GPHG, and the upcoming edition is no exception.

When traveling across the globe, there is nothing quite like having a watch on your wrist that can keep up with it. Measuring time in different time zones simultaneously is something that is not that extraordinary anymore, with nearly every brand offering at least one model that can do this. However, when you travel the world in the comfort of your own private jet, many of these watches simply won't do. Then you are looking for the best, the most complicated, the most expensive GMT-watches, and these Three might just fit the bill!

Due to a lack of peers, watches like the Graff MasterGraff GyroGraff World are best appreciated in their own realm, combining design, craftsmanship, and micromechanical engineering into a single object of art.

They might not always be the most obvious choices, but we fell in love with these four case backs for various, very good, reasons.

When it comes to ladies watches diamonds seem to be an almost mandatory ingredient, but why is this the case? And will this ever change?

A visit to Baselworld is a feast for the eye, as it offers some of the world's most spectacular watches. Exotic materials, intricate complications, and precious gem settings can quickly get the price tag up to astronomical heights. Here are five of the most expensive watches that were presented at the fair!

Just two years after introducing the titanium black DLC Graffstar Eclipse, Graff Luxury Watches presents the stunning Graff Eclipse Tourbillon.

Will people ever grow bored of tourbillons? Probably not, as they are still the preferred complication of many collectors. However, it is not only the complication itself that keeps the attention, but it is also the seemingly never-ending creativity of the watch brands who continue to dream up enticing new versions of it.

The time that quartz movements where the staple in women's watches is slowly passing. Over the last couple of years, the demand for mechanical ladies watches has grown significantly. With mechanical watches on the rise, also comes more interest in the more complicated movements.

Ask Haute Time's Director of Photography, Alex Teuscher, what he likes to do best, and you likely get as an answer " do a proper shoot". Unlike Baselworld or SIHH, where time is a rare commodity and equipment has to be unpacked and packed with each appointment, a proper shoot first of all means having time. Time to create something like these "Smokin' Hot Watches".

Boucheron, Cartier, Chanel, Graff, and Harry Winston bring us holiday cheer with these fabulous creations.
