The new Bentley Bentayga will offer an optional clock as expensive as the SUV itself.

If you’re going to build the world’s most expensive SUV, it might seem logical to offer the world’s most expensive in-car clock, as well.

At least, that’s what Bentley plans to do when it starts rolling out the new Bentayga in a few months. The full-size ute, with its leather and wood-lined cabin will start at $229,100 in the U.S. But you can bump that up with a variety of options – including the Breitling Mulliner Turbillon clock.

While a final price hasn’t been set, it’s expected to come in at around £150,000, or roughly $234,000 – which could make it more expensive than the “base” Bentley Bentayga. The maker justifies the price by explaining the clock has “the most complex of watch mechanisms.”

That means a mechanical, rather than electrical, self-winding mechanism. That’s easy to operate when you’re wearing one on your wrist, but to ensure the Mulliner Tourbillon stays wound on the dashboard, Bentley will build in an unusual mechanism that will spin the clock around three times every 15 minutes. And to be sure – or simply to impress friends – a motorist will have a button to tap to spin the watch one more time.

The new Bentley Bentayga is the first in an expected wave of ultra-premium SUVs.

Bentley, prides itself on allowing its customers to endlessly bespoke, or customize, its vehicles. You even can have the maker match your paint to the shade of a favorite shirt or scarf or lipstick. Surprisingly, then, the Breitling will only be offered in solid gold – though you will be able to choose between white or rose gold. A customer also will be able to pick from a black ebony or mother-of-pearl face. The clock is completed with eight large diamonds.

For those who can’t quite bring themselves to spend more on a clock than the car, all versions of the Bentley Bentayga will come with a standard, albeit less exotic, Breitling watch. The two companies have long partnered, and the watchmaker offers versions adorned with Bentley name one can wear, rather than drive.

What’s unclear is whether the Mulliner Tourbillon option will be ticked on the list when the first Bentley Bentayga is delivered in a few months. That one, it seems, will be going to a long-time fan of SUVs who’d like something a little more exotic than the Range Rovers she has traditionally used to get around her wooded estate, Balmoral Castle, in northern Scotland.

Even base versions of the new Bentley Bentayga will offer a Breitling clock standard.

Queen Elizabeth II already has an appropriately royal fleet of vehicles to choose from, including British-made products from Jaguar Land Rover, Aston Martin, Vauxhall and Bentley. The latter company modified its old Arnage to create the monarch’s current Bentley State Limousine.

Her Majesty apparently wants something a little more luxurious to take out when hunting. Among other things, the new Bentayga includes an “Event Seat,” a slide-and-fold system that can be used to tailgate party in style. Not only are there comfortable, fold-out seats but the Bentley Bentayga can be ordered with a built-in picnic basket slotted into its cargo compartment. Make that a portable catering system, as there are bins for china and silverware, as well as a compact powered food cooler.

No word if the royal Bentley Bentayga will be outfitted with a custom gun rack. But one wouldn’t expect a base model for a monarch who is expected to drive the new SUV herself around the estate.
