百達翡麗，不銹鋼自動上弦鏈帶腕錶，配中心秒針，動力儲存及日曆顯示，“Nautilus”，型號3710，1998年製

To the best of our knwoledge, the present example has never been offered in public before.

Reference 3710/1, launched in 1998, is the first “Jumbo” Nautilus produced since the legendary reference 3700 which was first produced in 1976. When launched, the Nautilus model was advertised as the most expensive steel watch on the market. The main difference between reference 3700 and 3710/1 is the addition of the sweep centre seconds and a power reserve indicator. Reference 3710/1 was discontinued in 2006.
