"We are very grateful to team Exe Endurow for choosing to raise money for the British Red Cross as they take on this incredible challenge," said Paul Amadi, Chief Supporter Officer, British Red Cross.

Amadi added, "The British Red Cross has supported people in crisis for over 150 years and the money raised will help us continue to support the most vulnerable people. The British Red Cross has helped the nation through its darkest days and coronavirus is no exception. We are focused on supporting people through this crisis by delivering food and medicine, making sure refugees and people seeking asylum are safe, and supporting the NHS to get patients home from hospital. We wish Arthur, Harry, Charles and Oliver the best of luck."

The Land Rover x Elliot Brown Holton Professional watch is based on the Elliot Brown Holton Professional watch, which was developed with a specialist branch of the U.K. special forces. It's built to withstand extreme military field tests and harsh environments.

Before customers take delivery, each watch must pass three separate pressure tests using air and water. In addition Elliot Brown watches have been put through real-world testing, surviving being strapped to the bows of round-the-world yachts and submerged to depths of 1,921 meters.

Its bolted-down compressor caseback system and triple-sealed crowns provide impressive water protection up to 200 meters. The case and strap bars are made from marine-grade 316L stainless steel. It also features scratch-resistant sapphire crystal glass.

According to its spec list, "the precision Swiss quartz movement is housed inside a proprietary shock protection system. The watch can survive the impact of a three kilogram stainless mallet which imparts a force of about 5000G." Additionally, the EPDM rubber strap is hypoallergenic and resistant to seawater, UV rays, and extreme cold temperatures. Buyers get a second strap option. The watch comes with an easy-to-change lightweight webbing strap with double selvedges and coated in an antibacterial treatment that is designed to last a lifetime.

It was the first watch supplied to the specialists after more than a decade without a suitable watch for their tough on-the-job conditions. The watch is also worn by Mountain Rescue England and Wales.

It comes with a five-year warranty and three-year battery life.

The Land Rover x Elliot Brown watch will be available in the U.S. later this year as part of the Land Rover brand's Above and Beyond collection of technical clothing and equipment.
