Patek Philippe 5800/1A

In 2006, Patek Philippe released the reference 5800/1A-001 (exclusively in steel) - featuring an automatic 330 calibre (SC) and ‘ridged' blue dial, with horizontal grooves. The 5800 marked the return of the mid-size Nautilus, previously discontinued in the early 00s (as the ref. 3800). Examples of the reference 5800 were produced for a limited time (approximately 1 year), representing an exceptionally rare and highly-collectible modern Patek Philippe.

The 5800 re-interprets a number of signature design elements from the original Nautilus - mostly notably, the monobloc case construction (with integrated sapphire case-back) - the only reference from the modern collection (2006) to do so. Similar to its earlier, mid-size predecessor, the 5800 measures 38.4mm (up from 37.5mm), comfortably suited to most wrist sizes. The steel, two-piece case provides water resistance up to 120m, further featuring a screw-down crown.

This steel, Nautilus 5800 watch is the perfect balance between utilitarian function and elegant design. The case and bracelet are excellently finished, with beveled, polished and granular surfaces. The steel bracelet has virtually no stretch. At 38.4mm in diameter, and only 7.8mm thick, the 5800 case is a unique twist of perspectives and size. The ‘ridged’ blue dial includes all the traditional indications of a time-only watch, with applied hour-markers and Nautilus hands (with luminescent inserts).
