The "S mark" at the 12 o'clock position is loved by collectors as a design symbolizing Seiko's post-war recovery. "UNIQUE" was born as the successor to the masterpiece "SUPER" and was a bridge to Seiko's golden age, leading to the later "MARVEL." It exudes a warmth and classic elegance unique to vintage watches, which cannot be found in modern timepieces. The dial is a silver dial with exquisite aging due to its age. It features a neat design typical of the 50s, combining flying Arabic numerals with wedge-shaped indices. ●Detailed Information ・Brand: SEIKO ・Model Name: UNIQUE ・Movement: Manual wind (15 jewels) ・Case Material: Stainless steel ・Dial Color: Silver (with the texture characteristic of antique items) ・Manufactured: Made in Japan ・Manufacturing Year: 1950s ・Vibrations: 18,000 bph (low beat) ●Size Case Width: Approx. 32mm (excluding crown) Lug Width: Approx. 16mm (Please allow for slight errors) ●Features ・Rare dial with "S mark" ・Good old Japanese antique design from the 1950s ・SEIKO genuine lizard-embossed leather strap (with SEIKO engraved buckle) ●Product Condition ・Overhauled: Measured with a timegrapher, the daily difference is approximately -3 minutes (this may vary depending on posture and usage conditions).
