The Nautilus reference 3712 was introduced in 2005 and had a very short production run. It is believed to have been made for only eight months and therefore the overall production output is rather low with an estimate of 1700 pieces being sold. At the time of production it was the most complicated Nautilus as it included, in addition to the date which previous models already had: moon phases, a power-reserve indication and subsidiary seconds. The way those indications and apertures are placed on the dial is particular, giving the watch a special touch. 

It was replaced in 2006 by the similar reference 5712, which was introduced to commemorate the 30th anniversary of the iconic Nautilus model. The two models can be distinguished by a few subtle difference to the dial, specifically the very small applied index at 7 o'clock which could be found on the 3712 but not on the 5712 and the three dots for the powerreserve against four on the 5712. Furthermore, the crown of the 3712 is larger that its successor.

The reference 3712, is a pivotal reference for the Nautilus line. It is a rare occasion to acquire this timepiece which has been produced for a very short period of time. It is also particularly exceptional to see such timepieces in its original factory seal.
