Description of the piece: Automatic robustness and characterful patina
This Omega Seamaster exemplifies to perfection the firm’s design evolution at the end of the 1960s and early 1970s, favoring cases with greater geometric presence and high-frequency automatic calibers.

Dial and Presence:
The original silver-toned dial shows a beautiful natural mottled patina that gives it unmistakable and honest vintage character, remaining unrestored. Its faceted, relief-textured hour indices stand out boldly, catching light in a three-dimensional way. At 3 o’clock sits the calendar window, elegantly framed, offering impeccable legibility. The slender baton hands and the outer minute scale complete a sporty yet sophisticated design, perfectly enhanced by a stainless steel milanese mesh bracelet that aligns with the lines of the case.

Case, Dimensions and Authenticity:
With notable measurements of 38.5 mm horizontal diameter and 42 mm lug to lug length, this cushion-shaped case offers a robust and very contemporary presence on the wrist, wearing more substantial than the traditional round designs of the era.

The back cover reveals in relief the iconic and historic Sea Monster Seahorse, an unmistakable emblem of the Seamaster lineage. On its inner reverse, the case back shows Omega Watch Co.’s classic authenticity seal, the inscriptions FAB. SUISSE / SWISS MADE and the alloy ACIER INOXYDABLE. Here the two official factory case references for this chassis are engraved: 166.087 (framed within the main design box) and 166.110.

The Heart of the Piece (Caliber 1002):
Inside beats the excellent Omega Caliber 1002 automatic with 20 jewels. This high-frequency movement features the characteristic and striking rose-gold copper plating of the brand and includes a skeletonized rotor bearing the Omega logo. The clearly engraved serial number on the plate places the manufacture of this mechanical heart in 1970. It is a modern caliber for its time, equipped with a quick-set date function and designed to deliver outstanding daily accuracy and performance.

Conclusion:
This Omega Seamaster is a solid, authentic piece rich in history. The combination of its 38.5 mm case, the robustness of the automatic caliber 1002, and a dial that proudly wears its patina, make it an ideal option for enthusiasts seeking a vintage watch with genuine personality and the reliability of one of Swiss watchmaking’s best eras.
