Omega Seamaster Cosmic 1968 — First impression - 135.016

The Omega Seamaster Cosmic Ref. 135.016 captures the late-sixties aesthetic with its streamlined monocoque case and elegant black crosshair dial. At 34 mm, it wears with effortless sophistication, balancing vintage charm and precision timekeeping. Applied batons with lume plots deliver excellent legibility, while the minimalist script at six adds period-correct character. The case’s brushed top and polished edges frame the dial cleanly and emphasize the Cosmic’s integrated, sealed construction. For collectors seeking a versatile vintage Swiss watch that pairs with tailoring as well as casual wear, this Seamaster Cosmic offers an authentic blend of design purity and mechanical integrity.

Omega Seamaster Cosmic - Black Crosshair Dial

The matte black dial is defined by a crisp crosshair motif that centers the layout and enhances readability. Applied baton hour markers with discreet lume dots sit over a precise minute track. The printed Omega logo at 12 and “Seamaster Cosmic” at 6 present the classic, uncluttered language prized by enthusiasts.

Seamaster Cosmic 135.016 - Hands

Faceted baton hour and minute hands with luminous inlays match the indices perfectly, accompanied by a slim central seconds hand. The polished surfaces play subtly with light, providing clarity without disturbing the dial’s measured restraint.

Omega Seamaster Cosmic 135.016 - Monocoque Stainless Steel Case

The stainless steel monocoque (front-loading) case was engineered for strength and a seamless profile. Its brushed upper surface and polished bevels preserve the sharp, purposeful look associated with the Cosmic line. At 34 mm, the watch slides under a cuff yet retains presence thanks to the oval-tonneau silhouette and domed crystal.

Seamaster Cosmic 135.016 - Crown

The original Omega-signed crown sits at 3 o’clock, proportioned to maintain the clean case lines while offering positive grip for daily winding and setting.

Omega Seamaster Cosmic Leather Strap

Paired with a brown stitched leather strap that complements the black dial and steel case, this configuration underscores the watch’s dress versatility and period spirit while ensuring everyday comfort.

Heritage of the Omega Seamaster Cosmic in the Late 1960s
