ANALYSE
This incredible and rare watch was the forefather of the Nautilus: this model has undergone evolutions up to the present day, yet has retained the integrity of its form and overall appearance. This original reference 3700/1, marketed since 1976, preserves all the secrets of a timeless design created by Gérald Genta, one of the most illustrious watch designers of all time.
The original matte dial, produced and handcrafted by the specialized craftsmen at Stern Fréres, is characterized by raised horizontal stripes. It features applied rectangular hour markers with luminous inserts at the hours. The minute track is white with vertical markings, a characteristic of the very first Nautilus series. This dial type is known as MK 0, the rarest and most sought-after version among collectors, as fewer than fifty examples are known to date. This specific dial was in fact only used for a few months, from the time of its presentation at the Baselworld 1976 show between April and May until its official market launch in July of the same year.
At 3 o’clock is the date window, well hidden on the dial: frameless, it was designed to be legible without intruding on the formal cleanliness of the overall dial layout.
At the center, below 12 o’clock, is the inscription “Patek Philippe Genève”; at 6 o’clock is the inscription “Swiss” between the Sigma symbols.
The hour and minute hands are typically rounded, baton-shaped at the ends, and also feature a luminous paste inside.
The two-piece case is a concentration of design innovations. Genta designed it starting with a very smooth octagonal bezel, without excessive edges, brushed on the surface and polished on the edge. Two lateral “wing” protrusions serve to connect the upper and lower sections with four screws. Water resistance is guaranteed to 120 meters.
From these premises, one of the most iconic watches of all time was born.
Another distinctive element is the wide and straight 16 mm integrated bracelet, composed of satin-finished links in the shape of an elongated “H” and a “cushion”-shaped link. The clasp is made with a folding clasp stamped with the Patek Philippe logo.
The self-winding movement was derived from a Jaeger-LeCoultre ebauche (cal. 920): this ultra-thin movement was renamed by Patek Philippe as the 28-255C.
This Patek Philippe Nautilus from the very first series (1976), original in all its parts and complete with box and cork paper, is an immortal watch.
