Here is a remarkably rare, highly collectible, and honest example of a 1952 Omega Seamaster Calendar, featuring a factory-original "Double-Signed" Türler dial. Türler was one of Zurich, Switzerland's most prestigious elite luxury retailers, making factory-stamped examples that are highly coveted by pure vintage horology investors. Aside from the rare co-branding, this timepiece features the iconic first-generation calendar layout, placing the date window symmetrically at 6 o'clock instead of the common 3 o'clock position.
Condition Report:
Dial & Hands: 100% original and untouched ivory/silver crosshair dial with applied gold arrowhead markers, 12-3-9 Arabic numerals, and matching Dauphine hands.
The dial shows a gorgeous, uniform cream patina with light, honest vintage aging spots that confirm its unrestored factory state.
Case: Excellent stainless steel "beefy lug" case profile.
The case preserves its robust vintage proportions, thick lugs, and sharp downward transitions with only light surface scuffs from careful historic ownership.
Crown: Retains its extremely rare, period-correct 10-sided Omega "Clover" / scalloped crown rather than a generic modern service replacement.Caseback: Features the historical and correct "Plain Center" style screw-down back with clear, crisp perimeter engravings reading "SEAMASTER" and "WATERPROOF", proving it has never been aggressively over-polished.
Internal Movement: Visually pristine under inspection, displaying the original signature Swiss copper-gilt plating on the automatic rotor assembly and main bridges.
Outstanding Mechanical Performance: The watch has been professionally benchmarked on a calibrated timegrapher at a precise 50.0° lift angle. It runs at modern chronometer precision, tracking at an incredible -1 second per day with a highly robust 240° amplitude and a very tight 0.6ms beat error. Buyers can purchase with complete confidence knowing this bumper caliber is performing beautifully and will not require immediate, expensive mechanical attention.
