\u00a0 The specifications you provided describe a highly collectible, early post-WWII <\/span>Omega Bumper Automatic (Reference 2398)<\/strong>. This timepiece is a classic \"pre-Seamaster\" model that dates to the late 1940s or early 1950s.<\/pre>\n

    Dial Condition:<\/strong> Vintage collectors place an immense premium on original, untouched dials. If the two-zone silver dial shows an honest, warm patina, the value remains high. Professionally redialed or refinished faces generally drop the market value by 30% to 50%.<\/span>\u00a0<\/pre>\n<\/li>\n
  • \n
    Case Sharpness:<\/strong> The lugs and bezels on solid gold models are soft. Over-polishing rounds out the crisp edges of the lugs and reduces gold weight. A case that retains its original lines commands top dollar.<\/span>\u00a0<\/pre>\n<\/li>\n
  • \n
    Crown and Components:<\/strong> Check if the winding crown is the original, period-correct Omega-signed variant. Later replacements from standard services are common but slightly detract from historical accuracy.<\/span><\/pre>\n<\/li>\n

    The Movement (Caliber 332):<\/strong> This watch is powered by the legendary Omega Cal. 332<\/strong>, which is a 17-jewel \"bumper\" (hammer) automatic movement. Unlike modern watches with a 360-degree rotating weight, a bumper movement utilizes a rotor that travels back and forth in an arc of about 120 degrees, hitting tiny springs at each end. This creates a distinct, tactile mechanical \"thump\" on the wrist that vintage collectors cherish.<\/span><\/pre>\n<\/li>\n
  • \n
    The Case (18k Rose Gold):<\/strong> While many Reference 2398 examples were cased in stainless steel or gold plating, a solid 18k rose gold<\/strong> version is a premium configuration. The 34mm<\/strong> diameter size is traditional for men's watches of that era. It wears slightly larger on the wrist than its numbers suggest due to the classic, elongated lugs.<\/span>\u00a0<\/pre>\n<\/li>\n
  • \n
    The Dial (Two-Zone \/ Bull's Eye Silver):<\/strong> A \"two-zone\" or \"Bull's Eye\"<\/strong> dial features a central disc finished differently from the outer chapter ring. This creates two distinct visual tones. It typically features an elegant sub-second register positioned cleanly at 6 o'clock.<\/span><\/pre>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
