Hublot has created the world's most costly watch, which was produced in limited quantities and is adorned with 1200 diamonds weighing 140 carats. It is made of six precious stones, and the business devoted 17 personnel to its production, which took 14 months.

According to a Hublot statement, unlike a conventional Haute joaillerie piece, where the design and construction fit previously picked stones, the diamond cutters started with the design and then located the diamonds that fitted it. Every stone was hand-picked to ensure that they were of uniform quality and color. They have to be resized one by one to fit perfectly with the watch. Beyonce Knowles, America's famed celebrity, paid $5 million for this watch for her husband Jay-Z.

Price: $5 million.

Hublot Million Dollar Black Caviar ranks number 2 on our list. Hublot Million Dollar Black Caviar is the watch that won the Geneve Jewelry watches competition in 2009. It is entirely formed of white gold, the weight of which is 18 carats.

Its setting is really intricate. The challenge stems from the Big Bang case's odd lines - spherical yet with sharp angles. The case's white gold, one-piece design conceals every grain of gold, and the diamonds, cut in unexpected ways, appear to hold together as if by magic. The sole noticeable characteristic is the diamonds' dark and deep tones, which shine in their harmonic alignment. It has no numbers on its face and comes with an adjustable leather strap. Its crown and clock are embellished with 544 beautifully cut diamonds weighing 34.5 carats.

Price: $1 million.

The MP-02 "Key of Time," arguably Hublot's most lyrical watch to date, is the closest we mere mortals will go to manipulating time to our will. The MP-02's innovative mechanism allows the user to modify the pace of time to travel four times faster or four times slower than the actual rate of time passing. The Key of Time also possesses "mechanical memory," which allows the hands to return to the right time regardless of how long the user has been time-traveling.

It is a highly practical timepiece that was produced in extremely limited quantities, with just 50 copies ever produced around the globe.

Hublot Bigger Bang is the first watch ever released by this company that includes a wheel chronograph that is upgraded with a diameter cage. With Baselworld 2015 approaching, it had been ten years since the Big Bang was first introduced. The Hublot universe is still expanding, with the installation of a new manufacturing facility this year, opposite the present one. Biver and Guadalupe have further concentrated on two essential elements: manufacturing and fusion, capitalizing on the velocity provided by the Big Bang. Prior to Biver joining Hublot, the business relied on various outside vendors for critical parts. Hublot, on the other hand, has spent the last decade focusing on transferring much of that knowledge and skill within its own organization, with the goal of controlling roughly 80% of the manufacturing of its watches.

It is built of about 262 distinct components, has a power reserve of 5 days, and is further upgraded with 33 valuable rubies to increase its beauty and also justifies making it entirely worth it for that.
