The Patek Philippe Nautilus reference Nautilus 3710⁄1A was introduced in 1998 and was first model in the line-up to feature a complication other than the date function. The matte black dial featured a power reserve indicator at 12 o’ clock. Unusual for the watches from the Geneva maison, the Patek Philippe signature was also placed at 6 o’ clock to make place for the power reserve indicator up top.

The Ref. 3710⁄1A was presented in a case with “Jumbo” proportions – the first time a 42 mm. case was used in a Nautilus other than the original Ref. 3700 – and was a departure from the mid-size cases in the Nautilus range.

It was produced only in stainless steel and was discontinued in 2006 to make way for the 30th anniversary line-up of the model. It is believed that around 4,000 pieces were made in total during the model’s short production run.
