Brand: Seiko Model: Business-A Reference Number: 8346-9000 Serial Number: 7217107 Movement: Automatic Caliber 8346 Dial: Silver Sunburst Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1967 Condition: Near-mint vintage condition, with only a little wear on the case and edges. Timegrapher testing indicates a daily rate of approximately -26 to -35 seconds per day, which indicates healthy movement operation running within acceptable vintage tolerances. Dial and Hands The silver sunburst dial is preserved in outstanding condition, radiating a clean metallic sheen that catches the light beautifully. It features multifaceted applied block indices that are polished to a high shine, providing excellent contrast against the silver background. The faceted dauphine hands are equally sharp, featuring slender strips of original lume that have aged consistently. A framed day-date aperture sits at the three o'clock position, balancing the layout. The text "Business-A" and "Diashock 27 Jewels" remains crisp and legible, showcasing the high-quality printing of the era. Case and Crystal The stainless steel case is a highlight of this reference, featuring the distinctive hidden crown located at the four o'clock position, which streamlines the silhouette for a perfect dress watch appearance. The case lines are incredibly sharp and well-defined, suggesting the watch has seen very little use over the decades. The polished surfaces gleam with minimal handling marks, and the lugs retain their original geometry. The screw-down caseback features the classic horseshoe text arrangement and is clean, with the reference and serial numbers clearly visible. The crystal is clear and free from distracting marks, allowing an unobstructed view of the dial. Movement Powering this timepiece is the robust Seiko Caliber 8346 automatic movement. This 27-jewel mechanism was a high-grade workhorse of the late 1960s, known for its efficiency and durability. The movement is winding and setting correctly. Timegrapher testing indicates a daily rate of approximately -26 to -35 seconds per day, which indicates healthy movement operation running within acceptable vintage tolerances. Strap The watch is fitted with a new, high-quality black leather strap with a crocodile grain pattern. This choice of strap complements the formal nature of the Business-A design, enhancing its presence as a dress watch while ensuring a comfortable fit on the wrist. Condition This timepiece is in near-mint condition, presenting a preservation quality that is rarely seen in watches from the late 1960s. The dial is flawless to the naked eye, and the case retains its factory sharpness with no significant scratches or dents. It stands as a collector-grade example of Seiko's design grammar from this specific period. Dimensions The case measures 37 mm in diameter excluding the crown, which was a substantial and modern size for a dress watch in 1967. The lug-to-lug length ensures a prominent yet elegant stance on a variety of wrist sizes, fitting easily under a shirt cuff due to the streamlined profile provided by the recessed crown. Remarks This Seiko Business-A is a testament to the build quality and design ethos of 1960s Seiko. It represents a specific moment in history when the brand was establishing itself as a world leader in watchmaking. Finding a 50-plus-year-old watch in such crisp, sharp condition is an uncommon opportunity. It is a piece that offers both historical significance and immediate wearability for the formal or casual enthusiast. History Produced in February of 1967, this watch comes from a vibrant era in Seiko's history. The "Business" series, including the Business-A and Business-M, was marketed towards the Japanese "salaryman"—the corporate warriors driving Japan's post-war economic boom. These watches were designed to be reliable daily companions that looked just as good in the boardroom as they did at evening social events. The use of the 8300-series movement places this watch in the upper tier of Seiko's commercial lineup at the time, showcasing the brand's commitment to delivering high jewel counts and advanced automatic winding systems to the public.
