A military Rolex watch so rare that money couldn't buy it is now going under the hammer in Wiltshire for thousands of pounds.

The rare Rolex 'Attack Force' watch was commissioned in 2014 as part of a collection to commemorate UK Apache operations and it is extremely limited as very few were made.

The watch was only offered to the longest-serving members of the British Army Air Corps at the time, and other members of the public couldn't access one.

But now, one Rolex Oyster Perpetual Date Explorer II Military wristwatch has made its way to Wiltshire and is expected to go under the hammer for over £16,000.

The extremely rare watch bears the Chief of Staff name 'Lt Col RGJ Stein' and the owner has decided to sell it at RWB Auctions in Royal Wootton Bassett.

“We are delighted to be offering this very rare Rolex watch," said Auctioneer Gareth Wasp.

"As they were made in such limited numbers this makes it very appealing to both collectors and watch dealers alike.

“The small group of Attack Force watches were commissioned in 2014 by the Military and produced by Rolex to commemorate UK Apache operations.

"They were offered to the longest serving members of the British Army Air Corps, this one to Chief of Staff Lt Col RGJ Stein.”

The rare Rolex will go under the hammer on Wednesday, March 27, as lot 448 and is estimated to sell for between £16,000 and £18,000.
