Launched in 1976, during the quartz crisis, the Nautilus is the second watch designed by Gerald Genta, after the Royal Oak in 1972. The shape of its case, very avant-garde for the time, reminds one of a porthole, which might explain its name after Captain Nemo's fictitious submarine, in Jules Verne's famous book Twenty Miles Under the Sea. The first reference is the 3700/1 manufactured with a 7.6 mm case, from 1976 to 1981. It is the most sought-after reference. The current example has been kept in very good original condition still showing nice angles to the case and bezel, the bracelet showing little wear and most importantly its original dial shows no defects or discolouration.
