The attractive combination of a gold-plated top case with a durable stainless steel back makes for a sophisticated dress watch that sits elegantly on the wrist, showcasing the timeless "stardust" aging that vintage enthusiasts seek. Brand: Eterna Model: Eterna-Matic Serial Number: 3949084 Movement: Automatic Eterna-Matic Dial: Champagne with applied gold markers Case Size: 33 mm (excluding the crown) Case Material: Gold Plated and Stainless Steel Production Year: 1952 Condition: Good vintage condition Dial and Hands The champagne dial has developed a consistent and charming stardust patina across the surface, giving the watch a unique vintage character. It features applied gold hour markers with Arabic numerals at 12 and 6, complemented by arrow-style indices elsewhere. The gold dauphine hands show normal signs of oxidation consistent with age, and the center sweep second hand adds to the dynamic layout. The iconic five-ball bearing logo is applied in gold below the 12 o'clock position. Case and Crystal The 33mm case features a gold-plated upper construction with distinct, faceted lugs that retain their architectural shape. There is expected surface wear, including light scratches and scuffs typical of a watch from this period. The screw-down caseback is made of stainless steel and is in good condition with visible opening marks. The acrylic crystal is generally clear, allowing for excellent legibility of the dial. Movement Powering the watch is a historic Eterna-Matic automatic caliber, featuring the famous friction-reducing ball-bearing rotor system. The movement is clean and aesthetically pleasing. Timegrapher testing indicates a rate of +28 to +35 seconds per day, which indicates a healthy movement running with strong amplitude and within acceptable vintage operating parameters. Strap The watch is fitted with a heavily distressed vintage leather strap in tones of brown and tan. The strap shows significant signs of wear and aging, contributing to the overall rugged vintage aesthetic of the piece. Condition This timepiece is in good vintage condition. The dial shows honest aging that enhances its appeal, while the case retains its structural integrity with normal wear to the gold plating on high points. The movement is functioning reliably. Dimensions The case measures 33 mm in diameter excluding the winding crown. The lug-to-lug length ensures a proportionate fit suitable for a classic dress watch profile. Remarks This Eterna-Matic is a quintessential example of 1950s Swiss design, balancing technical innovation with aesthetic elegance. The presence of the "five dots" logo on the dial is a subtle reminder of the engineering breakthrough hiding within the case. It serves as both a wearable accessory and a conversation piece for those who appreciate the evolution of the self-winding wristwatch. History Eterna is one of the most historically significant Swiss manufactures, credited with solving a major issue in automatic watches in 1948. By introducing five miniature ball bearings to support the oscillating weight, they drastically reduced friction and improved winding efficiency. This innovation was so successful that the five ball bearings became the brand's logo. This specific example, produced in 1952, comes from the golden age of this technology, representing the widespread adoption of the Eterna-Matic system that would eventually influence the entire industry.
