Brand: Seiko Model: Elnix Reference Number: 0723-6020 Serial Number: 3O1580 Movement: Electronic Balance Wheel Caliber 0723A Dial: Green Gradient Sunburst Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1973 Condition: Stunning vintage condition Dial and Hands The dial is the centerpiece of this watch, featuring a stunning green sunburst finish that graduates from a lighter center to a deeper emerald periphery. It is adorned with raised, block-style gold-tone hour markers that add depth and luxury to the face. The gold-tone baton hands are crisp and free of corrosion. A framed day-date window is positioned at 3 o'clock, featuring a highly desirable Kanji and English day wheel. The gold "SG" Elnix logo and applied Seiko branding remain bright and sharp. The dial surface appears flawless, interacting beautifully with the light refracted by the crystal. Case and Crystal The stainless steel case features the distinct, sharp angular geometry characteristic of Seiko's "Grammar of Design" influence during the 1970s. The edges remain well-defined, showcasing the original brushed and polished finishes. The absolute highlight of this timepiece is the original faceted cut glass crystal, which splits the dial into geometric segments. The crystal is in remarkable condition, preserving the intricate prism effect that makes this model so collectible. The crown is recessed at the 4 o'clock position, maintaining the sleek silhouette of the case. Movement Powering the watch is the Seiko Caliber 0723A, a 16-jewel electronic movement. This is a fascinating hybrid mechanism that utilizes a battery to power a traditional balance wheel, resulting in the smooth sweeping second hand beloved by mechanical enthusiasts. The movement is clean, with the distinctive blue electronic bridge clearly visible. Timegrapher testing shows the watch is running between +6s and +15s/day, which indicates a healthy movement performing excellently for its age. Strap The watch is fitted with its original vintage Seiko stainless steel bracelet. The bracelet features a multi-link design that complements the retro-futuristic look of the case. It is secured by a signed Seiko deployment clasp. The bracelet is currently sized to fit a wrist of approximately 18cm. Condition This timepiece is in stunning vintage condition. The dial is pristine, showing no visible signs of aging or staining. The faceted crystal is exceptionally clear, which is rare for these models as they are prone to chipping. The case shows only very minor handling marks consistent with careful storage and light wear, retaining its sharp factory lines. The movement is clean and functioning reliably. Dimensions The case measures 35mm in diameter excluding the crown, offering a classic vintage fit that wears slightly larger due to the angular case shape and faceted crystal height. Remarks The Seiko Elnix represents a fleeting but fascinating moment in horological history, sitting between the mechanical dominance of the 1960s and the quartz revolution of the late 1970s. Finding an example with a green dial and an intact faceted crystal in this condition is becoming increasingly difficult. This is a functional piece of art that embodies the bold, experimental spirit of 1970s Japanese watchmaking. History Introduced in the early 1970s, the Elnix series was marketed to a younger, trend-conscious demographic in Japan, offering "electricity" (Electronic) and "nix" (Phoenix) to symbolize a new era. It was one of the last and most advanced electronic balance wheel watches produced by Seiko before Quartz became the standard. The serial number on this specific piece dates its production to October 1973, placing it right in the heyday of this colorful and innovative period. / Second Vintage SKU: SEIKWI6IN0000
