Emmanuel (quattro) offers a compelling deep dive into two often-overlooked Patek Philippe Nautilus references, the 3800/1A-001 and 3710/1A-001. His detailed analysis highlights their unique characteristics, such as Roman numerals and distinct complications, positioning them as attractive alternatives for collectors who appreciate dressier interpretations of the iconic sports watch. This article provides valuable context for understanding the evolution of the Nautilus line beyond its most famous iterations.

For those who, like me, are more attracted to dress watches than to sports watches, the Patek Philippe ref. 3800/1A-001 (or 3800/1A-XII) & 3710/1A-001 might be the best iterations of the Nautilus. At least, personally, they're the ones I feel the most attracted to.

Introduced in 1981 (but available only one year later in 1982) and produced until 2006, the ref. 3800 was the midsize brother of the original ref. 3700, with a 37.5 mm case (instead of 42 mm). It was the first Nautilus with an in-house automatic movement, caliber 335 SC with central seconds (the letters SC stand for 'seconde centrale' in French and the original ref. 3700 didn't have a seconds hand). The caliber was later improved with a quick-set date, the Geneva Seal and a 3 Hz frequency and became 330/134 SC in 1992 and 330/194 SC in 1997. The ref. 3800/1A-001 with white gold applied Roman numerals seems to have been introduced in 1996 and has a deep black lacquer dial with leaf hands and a printed railroad minutes track. This model is historically important, because it served as a model for the precursor of the Aquanaut: the ref. 5060S (about which I posted here).

Introduced two years later in 1998, the ref. 3710/1A-001  sometimes referred to as 'The Comet' was the first-ever Nautilus to feature a complication other than the date or central seconds function, with the integration of a power reserve indicator made of a metallic graduated scale that rotates as the watch is being wound and a pointer that rotates as power is discharged. It was also the first time that the original 'Jumbo' case proportions (42 mm) were used in a Nautilus other than the initial 3700. Exclusively produced in stainless steel until it was discontinued in 2006, the 3710/1A-001 features a matte black dial with applied Roman numerals and a central seconds hand. The power reserve indicator, or IZR for 'Indication de Zone de Remontage', is displayed between 11 & 12 o’clock, an asymmetric placement which makes this reference even more charming, imo. The brand signature is unusually placed at 6 o'clock.

These two models are presented in reverse chronological order.

Have a great Sunday!

About the Patek Philippe Nautilus Jumbo Ref. 3700

The Patek Philippe reference 3700 is recognized as the original Nautilus model. It established the distinctive porthole-inspired case design and integrated bracelet that define the collection. This reference was produced for a significant period, laying the foundation for subsequent Nautilus iterations and solidifying its place in the brand's sports watch offerings.

This reference features a stainless steel case measuring 42 mm in diameter and 7.6 mm in thickness, fitted with a sapphire crystal. It houses the self-winding Caliber 28-20 C, which provides a power reserve of 45 hours. The watch is water-resistant to 120 meters and typically presents with a blue dial, offering a date complication.

The 3700 appeals to collectors interested in the foundational pieces of significant watch lines. It represents the initial vision for the Nautilus, preceding later mid-size and complicated versions. Its production run from 1976 to 1990 saw various dial and bracelet configurations, making specific examples of interest to those studying the model's evolution.

The “comet” power reserve is a cool 😎 looking function ! For me, the Roman numerals make the dial busy 😅

And I know that to many Nautilus lovers, these are mostly 'ugly ducklings'. But it doesn't stop me from liking them! Have a great Sunday. Cheers, Emmanuel

I never thought I would ever buy one But I did and I find the dial , Roman numerals and the comet feature quite charming I also had the ref 3800 but it was a bit small and I traded up into the 3710 I think this watch has to be seen in the flesh to appreciate it charms Thanks for highlighting

As you've understood, I like this unconventional model. The blue dial 3700 (or 5711, but I tend to prefer the monobloc case) are attractive, of course. But they don't make me dream (personal taste, of course). Cheers, Emmanuel
