The nickname refers to the two red printed lines on the dial. The 'Sea-Dweller 2000' was one of the first production watches to employ a gas-escape valve on the band of the case, which allows the interior of a watch to decompress and avoids damage. The one way valve automatically releases built up gas from inside the case when the diver rises from the deep sea environment without which the watch would be in danger of popping the seals. Interestingly, the plexi glass covering the dial did not feature the usual cyclops magnifying the date window as it adds a pressure point which would cause a weakness. 拍卖场通知 Please note that this lot has been withdrawn.
