Dial and Hands
The dial of this Seamaster presents a striking, highly patinated vintage aesthetic. Originally a silver sunburst finish, the surface now exhibits heavy, widespread spotting and freckling across the entirety of the dial, often referred to by collectors as a "stardust" effect. This oxidation is prominent and uniform, fundamentally altering the dial's original appearance into something uniquely aged. The dial furniture remains excellent, featuring applied faceted baton indices with black inserts that provide strong contrast. A framed date window is positioned at three o'clock. The classic dauphine hands feature matching black inserts and show visible oxidation and aging consistent with the dial's overall condition. The applied Omega logo, "OMEGA AUTOMATIC" text, and the elegant "Seamaster" script remain crisp and fully legible despite the heavy surface patina.
Case and Crystal
The 34mm stainless steel case features a classic profile with thick, slightly sweeping lugs and a smooth polished bezel. The case exhibits honest signs of wear, including moderate surface scratches and minor softening of the lug edges consistent with a watch of this era, yet it retains its fundamental geometry. The watch is fitted with a signed, scalloped Omega crown that adds a touch of factory originality. The domed acrylic crystal shows minor surface wear but provides a clear view of the patinated dial beneath. Turning the watch over reveals a screw-down caseback highlighted by a deeply embossed Hippocampus medallion and "SEAMASTER" text, which remains remarkably crisp and well-preserved.
Movement
Powering this timepiece is the esteemed Omega Caliber 562 automatic movement, featuring 24 jewels and finished in Omega's signature copper plating. The movement presents beautifully under inspection, with clean bridges, an intact rotor, and crisp factory engravings. The serial number 22763670 is clearly stamped on the movement bridge, accurately dating the watch's production to approximately 1965. Performing well within expected vintage tolerances; running strong and steady. (+20 to +22 s/d).
Strap
The watch is fitted with a period-correct stainless steel bracelet featuring polished center links and brushed outer links. The endlinks are stamped with the code 455 B1. The bracelet shows typical vintage stretch and surface scratches that match the wear profile of the case, offering a cohesive look and comfortable wear for a wrist size of up to 18 cm.
Condition
This timepiece is presented in good vintage condition. The stainless steel case and bracelet show honest, age-appropriate wear, including surface scratches and handling marks, without any severe gouges. The dial is the defining feature of this watch's condition, displaying heavy, distinct spotting, oxidation, and patina throughout, which will appeal to collectors seeking a heavily aged, character-driven aesthetic. The movement is remarkably clean, and the caseback medallion is in excellent, sharp condition.

History
Introduced in 1948 to coincide with Omega's 100th anniversary, the Seamaster line was born from the brand's experience producing rugged, water-resistant watches for the British military during the Second World War. Omega combined this durable, waterproof technology with elegant, dressy designs to create the ultimate daily-wear watch for the post-war era. By the 1960s, the Seamaster had evolved into a symbol of refined reliability, utilizing sophisticated automatic movements and timeless case proportions. References from this era, equipped with the Caliber 560 series movements, are highly regarded for their mechanical excellence and remain a cornerstone of vintage watch collecting today.
