Who knew that Dodge makes motorcycles? Well not even Dodge because according to them, they don’t. The Tomahawk is a concept vehicle and is only “a piece of automotive sculpture”. The 8.3L V10 engine was lifted out of a Viper and dropped into an Art Deco-body. Dodge initially claimed that the Tomahawk is capable of travelling at 680km/h (420mph) They later admitted it was more like a theoretical 500km/h, before emphasising that the bike isn’t for riding at all.

How rare a watch is can dictate its price so, at $4.6 million, you can be sure that the Louis Moinet Meteoris is pretty rare. In fact, only four of these watches were created, and they each contain something very special. As well as being beautifully crafted, each Meterois watch impressively includes moon rock.

Ecosse top the list with a bike that was intended to revolutionise motorbike design. It was the brainchild of Dick Glover, technical director of McLaren Automotive. Glover reasoned that instead of relying on raw power, he’d use F1 technology to improve performance. He applied new materials to strip away the weight and improve aerodynamics and electronics to improve handling and performance. The only thing he couldn’t optimise was the price tag, so for now, the future of motorbike design remains ahead of its time.

Building on earlier designs, Richard Mille created the RM 56-02 Sapphire Tourbillon. More complicated and stylish than the watches before it, this timepiece today merits a $2 million price tag. While its appearance is about as cool and unique as a watch can be, it’s the craftsmanship that gives this luxury piece its high value. The detailed case design and extraordinarily complex movement are both forged out of pure sapphire with the latter also suspended in the air by cables.

Russian billionaire Roman Abramovich is owner of the Eclipse.it was built by Blohm and Voss of Hamburg and measures 536 feet long also making it the second largest in the world.

It features 24 guest cabins, two swimming pools, several hot tubs, and a disco hall not to mention the two helicopter pads, three launch boats and mini-submarine capable of submerging up to 50 metres underwater.

The ‘Million dollar Harley’ is a custom bike by legendary builders Bartels with a paint finish by maverick artist Jack Armstrong, using his signature Cosmic-style painting. “As an artist, Harley is James Dean, Brando, Elvis and Steve McQueen, and is more American than ice cream,” said Armstrong. It’s unique and it’s yours for one million dollars.

The B-2 Spirit was launched in 1989. The program to develop it was initiated during the Carter administration in the late 1970s. Northrop was chosen to build this fighter plane. The highlight of its design is a technique called “continuous curvature” which deflects radar. In fact, its radar cross-section is just 1.1 square feet – the size of a pigeon. The bomber was first deployed in action in the Kosovo War in 1989 where it flew 50 sorties.

The B-2 costs about $135,000 per hour to operate. It has a flying range of 6,000 nautical miles, and refuels every six hours. The plane has amenities such as a hot plate to prepare food, a bed, and a toilet. One pilot can sleep at a time on long missions, minimizing fatigue during round-the-clock flights. The fighter jet has a quadruple fly-by-wire flight control system, split brake-rudders, and differential thrust to maneuver which keeps its radar cross-section low. Its engines are concealed in the wing, hiding fan blades from radar, and reducing the engine’s heat signature to prevent detection by infrared tracking systems. Finally, the B-2 can hit a top speed of 1,010 km/hour.

The title of the most expensive watch in the world goes to Graff Diamonds for the incredible, Hallucination. Worth a whopping $55 million, the Hallucination is a masterpiece with over 110 carats of coloured diamonds set into a bracelet of platinum.

Ecosse is so exclusive that you’ve probably never even heard of them. Based in Denver, Colorado, the company is masterminded by former racer and engineer Donald Atchison. He wanted to bring the same level of precision engineering, finesse and sheer luxury that he saw in top-end cars (particularly Aston Martins) to two-wheels. The Titanium’s aluminium 2.4 litre engine develops 225bhp, the chassis and exhaust is made from, well, titanium but at least it comes with a free BRM Titanium watch.

Zenith enters this list with a masterpiece. The Chronomaster is a timepiece of pure art and engineering. Through its open-worked dial, everything is laid out in the open. The visible inner workings of the movement add to the design of this intricately crafted beauty. It works well both as rugged wear and as a dress watch for more formal occasions. You have your choice of color for the dial, hands, and bezel as well as a choice of strap material.
