Omega Seamaster Automatic Day-Date Ref. 166.0264 – Rare Vertical-Lined Dial with Original Jubilee Bracelet

The Omega Seamaster Automatic Day-Date Ref. 166.0264 represents one of the most distinctive and undervalued expressions of Omega’s late 1970s to early 1980s design. Produced around 1980, this 34mm stainless steel timepiece pairs a crisp case, a rare vertically-textured silver dial, and the highly sought-after original Omega Jubilee bracelet (Ref. ST1351.339.42), making it a standout for collectors searching for uniqueness and originality.

A Sharp Steel Case with Original Finish

The 34mm stainless steel case presents in remarkably sharp, unpolished condition, retaining the original brushed factory finish. Its crisp lines and untouched geometry highlight the care with which this piece has been preserved. At this size, the watch wears comfortably while still offering strong wrist presence thanks to its angular late-70s design cues.

The Dial – Rare Vertical Texture

The original silver dial, in excellent condition, is defined by its rare vertical line finish – a subtle yet striking detail that immediately distinguishes this Seamaster from more common examples. The applied indices, matching hands, and framed day-date aperture all remain crisp and original, while the Omega signature crown reinforces its authenticity.

Above, a clean mineral glass crystal protects the dial, providing excellent clarity with vintage charm.

Bracelet – The Omega Jubilee

Perhaps the most exceptional feature of this piece is its original Omega Jubilee bracelet, Ref. ST1351.339.42. Known for its comfort, fluidity, and vintage elegance, the Omega Jubilee is seldom seen on this reference and adds both rarity and collector appeal. This example remains long, accommodating a wide range of wrist sizes.

Inside the Case – Omega Calibre 1020

Powering this Seamaster is the automatic Omega Calibre 1020, a robust and precise movement with a quickset day-date function. This example has been recently serviced by a professional watchmaker, ensuring smooth performance, accuracy, and reliability. Its combination of practicality and Omega’s solid engineering makes it ideal for both daily wear and long-term collecting.
