Orient - Chrono Ace "Vivid Green Sunburst" 放光 – Hōkō – Emitted Light - No reserve price - Men - 1970-1979

Presented for auction by Second Vintage This is a spectacular example of 1970s Japanese horological design, showcasing Orient's creativity during the golden age of mechanical watches. The "Chrono Ace" model is highly collectible, but this specific reference is particularly desirable due to its stunning emerald green shell dial and original faceted cut-glass crystal. The iridescent play of light across the dial, combined with the geometric distortions of the crystal, creates a visual depth rarely seen in vintage timepieces. Brand: Orient Model: Chrono Ace Reference Number: F429-25960 Movement: Automatic Caliber 42970 Dial: Emerald Green Shell Case Size: 38 mm (excluding the crown) Case Material: Stainless Steel Production Year: c. 1970s Condition: Near-mint vintage condition. Timegrapher readings indicate an accuracy between +8 and +11 seconds per day, which indicates a healthy movement running very well within vintage tolerances. Dial and Hands The dial is the standout feature of this timepiece, crafted from natural shell with a deep emerald green finish that features incredible iridescence and texture. The applied silver block indices are polished to catch the light, matching the baton-style hands. A framed day-date aperture is positioned at 3 o'clock. The dial is protected by a faceted "cut glass" crystal, a signature of high-end 70s Japanese designs, which remains in clean condition and amplifies the dynamic look of the dial. Case and Crystal The stainless steel case measures 38mm and features a distinctive cushion shape with a C-line profile, offering a comfortable and substantial presence on the wrist. The finishing alternates between brushed upper surfaces and polished sides. A distinct feature of this movement is the pusher located at the 2 o'clock position, used for quick-setting functionality. The case retains sharp factory lines. Movement Powering the watch is the robust Orient in-house automatic Caliber 42970, boasting a high jewel count of 27 jewels. The movement is clean and the rotor is signed. Timegrapher readings indicate an accuracy between +8 and +11 seconds per day, which indicates a healthy movement running very well within vintage tolerances. Strap The watch is fitted with a black leather strap featuring contrasting yellow stitching, which complements the sporty yet elegant nature of the watch case. Condition This timepiece is in near-mint condition. The dial is flawless, and the faceted crystal is clear. The case shows only very minimal signs of handling, with a little wear on the case edges and small, faint hairlines visible only upon close inspection. It presents as a very fresh and well-preserved example. Dimensions The case measures 38 mm in diameter excluding the crown. Remarks Finding an Orient Chrono Ace with a shell dial in this condition is becoming increasingly difficult. The combination of the high-beat era aesthetics, the complex faceted crystal, and the exotic dial material makes this a unique value proposition for collectors of Japanese vintage watches. History Orient Watch Co., established in 1950 in Tokyo, earned a reputation for producing robust and innovative mechanical movements that rivaled their larger domestic competitors. The Chrono Ace (or "CA") line was introduced in the late 1960s and represented a higher-tier offering, often featuring high jewel counts and exotic dial materials such as Jaguar Focus or Mexican Shell. These watches are now celebrated icons of the funky, experimental design language of the 1970s. /Second Vintage SKU: ORIRX0YFR0000
