百達翡麗，精細及罕有，不銹鋼自動上弦鏈帶腕錶，配中心秒針及日曆顯示，“Nautilus”，型號3710/1A，附證書及盒子，2000年製

Reference 3710/1 launched in 1998, is the first 'Jumbo' Nautilus produced since the legendary reference 3700 which was first produced in 1976. When it launched, the Nautilus model was advertised as the most expensive steel watch on the market. The main differences between reference 3700 and reference 3710/1 are the sweep seconds as well as the up-down indicator. Reference 3710/1 was discontinued in 2006. According to our research, the present watch is fresh to the market.
