Our remarks
PATEK PHILIPPE NAUTILUS – Ref. 3800/1
A Rare 18k Yellow Gold Genta-Designed Sports Icon with Diamond Sigma Dial, about 1989
We are pleased to offer this excellent Patek Philippe Nautilus Ref. 3800/1, presented in 18k yellow gold with matching integrated gold bracelet.
This exeptional 3800/1 is accompanied bay:
- Original Box
- Extract from the Archives (ordered).
Launched in 1981 as the midsize successor to the original Ref. 3700, the 3800 maintained the same elegant proportions and porthole-inspired case design, while offering a more wearable 37.5mm case size. This particular example is distinguished by its factory-set blue Sigma dial with applied diamond hour markers — a dial variation that underscores the blend of sportiness and quiet opulence that defines the Nautilus line.
The deep blue dial, signed with the “σ SWISS σ” hallmark at 6 o’clock, confirms the use of solid gold markers and hands — a detail collectors increasingly value.
Fully original 18k yellow gold bracelet, still exhibiting its original stiffness
Remarkably well preserved, this example offers razor-sharp edges, a flawless dial, and a bracelet that has retained its structure — often lost in examples of this age. The case and bezel appear unpolished, adding to the desirability of this highly collectible timepiece.
With the rising appreciation for classic Geral Genta designs — especially those in precious metals and rare dial configurations — this diamond-dial Ref. 3800/1 stands out as a rare opportunity, so don’t miss this one!
Includes a one-year mechanical warranty from our in-house watch lab.
