Brand: Omega Model: Speedmaster Date Chronograph Reference Number: 3513.50 Serial Number: 58426182 Movement: Automatic Caliber 1152 Dial: Black with heavy stardust patina Case Size: 39 mm Case Material: Stainless Steel Production Year: 1998 Condition: Good vintage condition, with visible patina showing. Timegrapher testing indicates a rate of approximately -6 to -9 seconds per day with strong amplitude, which indicates strong and healthy movement function. Dial and Hands The dial has developed a significant and uniform stardust patina across the black surface, transforming the original finish into a textured, galaxy-like appearance that is highly specific to this individual piece. The sub-dials at six, nine, and twelve o'clock remain legible, arranged in the classic configuration with a date aperture located at the three o'clock position. The hands exhibit visible oxidation and aging that matches the heavy patina of the dial, contributing to the watch's raw and unpolished vintage look. Case and Crystal The 39mm stainless steel case features Omega's iconic twisted lyre lugs and a fixed steel tachymeter bezel. The case shows evident signs of wear, including scratches and scuffs on the polished and brushed surfaces, consistent with a watch that has been worn and enjoyed. The steel bezel retains legible black numerals despite surface marks. The sapphire crystal is in good condition, allowing for a clear view of the unique dial texture beneath. Movement Inside beats the Omega Caliber 1152, a robust automatic chronograph movement based on the reliable Valjoux 7750 architecture. The movement is visually clean and is currently running within vintage tolerances. Timegrapher testing indicates a rate of approximately -6 to -9 seconds per day with strong amplitude, which indicates strong and healthy movement function. Strap The watch is fitted with its original Omega stainless steel bracelet, reference 1562 with 850 end links. The bracelet features a deployment clasp with the Omega emblem and exhibits stretch and surface scratches consistent with the case condition. It is currently sized to fit a wrist circumference of approximately 18cm. Condition This timepiece is in fair vintage condition, characterized by heavy, distinctive aging on the dial and hands, along with honest wear to the case and bracelet. While cosmetically weathered, the watch is mechanically sound and presents as a piece with significant history and character. Dimensions The case measures 39mm in diameter excluding the crown, offering a versatile size that fits comfortably on a variety of wrist sizes. Remarks The watch comes with its original Omega International Warranty card, bearing the matching serial number. The specific aging on this dial makes it a unique proposition for collectors who value patina and individuality over pristine preservation. History The Speedmaster family is arguably the most famous lineage in chronograph history. While the manual-wind Professional went to the moon, the Speedmaster Date automatic series was developed to offer the same sporting DNA in a more convenient, daily-wear package. This model from the late 1990s captures the transition of the Speedmaster into a modern luxury staple while retaining the tool-watch utility of its predecessors.
