The Dive Watch - a succinct history (3)

2009 - CX Swiss Military unveils the 20,000 Feet, which breaks the Rolex Deepsea’s record for water resistance (20,000 feet is equal to about 6,100 meters) and enters the Guinness Book of Records. (CX Swiss Military had held the deepness record from 2005 until the Deepsea appeared in 2008.) The watch is a chronograph with a 28.5-mm-thick case and a domed back. According to CX Swiss Military, it is actually water-resistant to 7,500 meters, thus providing the 25-percent margin of safety required to meet ISO 6425.
