Omega - Seamaster Electronic f300 Hz Chronometer - No reserve price - 198.012 - Men - 1970

Offered in this auction by Second Vintage Embodying the bold aesthetic and technological ambition of the early 1970s, this Omega Seamaster Electronic f300 Hz Chronometer stands as a fascinating artifact of horological history. Born during a brief but brilliant transitional era when tuning fork movements represented the absolute pinnacle of precision, this timepiece combines striking UFO-style case geometry with a highly sophisticated mechanical-electronic caliber. With its prominent red Omega shield and sweeping red seconds hand, it offers a distinctively retro-futuristic charm that appeals strongly to collectors of unconventional and historically significant vintage watches. Brand: Omega Model: Seamaster Electronic f300 Hz Chronometer Reference Number: 198.012 Serial Number: 32665694 Movement: Caliber 1250 tuning fork, 12 jewels Dial: Silver dial displaying heavy, even spotting and stardust patina, with applied black faceted indices Case Size: 40 mm (excluding the crown) Case Material: Stainless steel Production Year: 1970 Condition: Good vintage condition with sharp case geometry and heavy dial patina Dial and Hands The dial presents a silver base that has developed a highly pronounced, evenly distributed spotting and stardust patina across its entire surface, reflecting clear signs of vintage aging. An applied red Omega shield sits prominently beneath the 12 o'clock marker, positioned above crisp black printed typography denoting the electronic tuning fork technology. The hour markers consist of applied, faceted black batons that provide excellent contrast against the textured dial, each flanked by aged tritium luminous dots at the outer minute track. A stepped, framed date aperture is positioned at 3 o'clock. The time is indicated by black baton hour and minute hands showing matched aging, complemented by a vibrant red sweeping seconds hand that glides with the characteristic smoothness of a tuning fork mechanism. Case and Crystal The 40 mm stainless steel case features a massive, distinctive UFO or helmet-style profile characteristic of the era. The case geometry remains remarkably sharp, showcasing prominent concentric brushed finishing across the broad upper bezel surface, which transitions cleanly to horizontal brushing along the sculpted flanks. A recessed, Omega-signed crown is tucked neatly into the case side at 3 o'clock. The watch is fitted with a flat crystal that exhibits a visible brownish tension ring at its perimeter. Turning the watch over reveals a screw-down stainless steel caseback featuring a deeply engraved and beautifully preserved Seamaster Hippocampus medallion. While the exterior case shows only moderate, honest handling marks, the interior caseback rim and movement ring display heavy deterioration and melting of the internal black rubber gasket, a common occurrence in watches of this specific vintage. Movement Powering this timepiece is the Omega Caliber 1250, a copper-finished, 12-jewel tuning fork movement licensed by Bulova and based on the ESA 9162 ebauche. The movement plates are clearly stamped with the Omega branding, caliber number, and the serial number 32665694, which accurately dates the production of this watch to 1970. The internal architecture showcases the fascinating electromagnetic coils and tuning fork mechanism that define this brief era of watchmaking. The movement is presented in operational condition, reflecting the unique mechanical character of early electronic horology. Strap The watch is secured by a the original stainless steel bracelet featuring a multi-link construction that integrates seamlessly with the hooded lug design of the case. The links exhibit a brushed finish that complements the case texture. The bracelet is completed by an original folding clasp, which is deeply stamped with the Omega logo on the outer cover, showing normal vintage wear consistent with the rest of the timepiece. Condition This Seamaster is presented in good vintage condition. The exterior stainless steel case is a highlight, retaining crisp edges and strong factory brushing patterns with only moderate surface wear. The dial exhibits heavy, distinct spotting and patina throughout, presenting an aged aesthetic that contrasts with the sharpness of the case. The internal movement ring shows significant degradation of the original rubber gasket, which is contained within the caseback area. Dimensions The case measures 40 mm in diameter excluding the crown. Remarks This timepiece captures a highly specific moment in watch design, merging the robust, oversized steel cases of the 1970s with the smooth-sweeping fascination of tuning fork technology. It is a substantial watch on the wrist, offering a commanding presence and an excellent conversation piece for enthusiasts of unconventional vintage Omega models. History Before quartz technology completely dominated the industry, tuning fork movements were celebrated as the ultimate solution for high-precision timekeeping. Utilizing technology originally developed by Max Hetzel for Bulova, Swiss manufacturers formed a consortium to create the ESA 9162, widely regarded as the finest tuning fork movement ever produced. Omega adopted this caliber as the 1250, regulating it to such exacting standards that it achieved official chronometer certification. These f300 Hz models represent a brief, brilliant chapter of innovation, bridging the gap between traditional mechanical mainsprings and modern quartz oscillators. / Second Vintage SKU: OME-SCX-0004
