Omega - Seamaster - 2577-24 SC - Men - 1948

Available now on auction by Second Vintage This early example of the Omega Seamaster is a significant piece of horological history, dating back to the very inception of the legendary model line in the late 1940s. Featuring the robust "fat lug" case design that defined the reference 2577, this timepiece houses the desirable Caliber 351 bumper automatic movement, a mechanism celebrated by collectors for the tactile feedback of its rotor. With its classic dial layout and honest vintage character, this Seamaster represents the golden era of Swiss tool watches, offering a blend of sporty durability and dress-watch elegance that remains timeless today. Brand: Omega Model: Seamaster Reference Number: 2577-24 SC Serial Number: 11113291 Movement: Automatic Bumper Caliber 351 Dial: Silver with applied Arabic numerals Case Size: 34 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1948 Condition: Good vintage condition. The watch presents an honest aesthetic with visible aging to the dial and normal wear to the case, preserving its historical integrity. Dial and Hands The dial features a silver backdrop that has developed a consistent, stardust-like patina across the surface, characteristic of genuine age. It is adorned with applied silver dart indices and Arabic numerals at the quarter hours, creating a classic mid-century layout. The time is displayed by polished steel Dauphine hour and minute hands which retain their sharp profile. The script "Seamaster" features the collectible "coat hanger" S typography, confirming its early production lineage. Case and Crystal The stainless steel case, stamped "Acier Staybrite" on the interior, is defined by the thick, curved lugs that give the reference 2577 its substantial presence on the wrist. The case shows surface scratches and marks consistent with decades of use, maintaining its original definition without signs of over-polishing. The caseback is the screw-down type for water resistance. An original Omega-signed crown is fitted to the case. The acrylic crystal is clear with minor handling marks. Movement Powering the watch is the renowned Omega Caliber 351, a bumper automatic movement that relies on a hammer rotor striking springs to wind the mainspring. The movement presents well visually with copper-colored plating and is signed with the Omega logo and 17 jewels. Timegrapher testing shows the movement is running with a rate of approximately +52 to +60 seconds per day, which indicates a movement that is beating actively, but could benefit from adjustment in the future. Strap The watch has been fitted with a new black leather strap featuring contrasting white stitching and a textured finish, complementing the steel case and vintage dial. It is secured by a standard steel pin buckle. Condition This timepiece is in good vintage condition. The dial shows evident spotting and oxidation, often referred to as tropical or stardust patina, which many collectors find adds to the unique character of the piece. The case retains its structural integrity with expected surface wear. The movement is functioning and winding correctly via the bumper mechanism. Dimensions The case measures 34 mm in diameter excluding the crown, a classic size for the era that wears slightly larger due to the robust lug design. Remarks This Seamaster Ref 2577 is a quintessential collector's piece, featuring the "SC" (Seconde Centrale) case designation. The combination of the bumper movement and the heavy lug case makes this one of the most sought-after early Seamaster variations. History Introduced in 1948 to celebrate Omega's 100th anniversary, the Seamaster was based on waterproof wristwatches made for the British military during World War II. This specific example, produced in the model's debut year of 1948, serves as a foundational piece of the collection that would go on to become Omega's longest-running product line. The use of the bumper automatic movement places it firmly in the transitional post-war era of watchmaking innovation. / Second Vintage SKU: OME10AULJV000
