The reference 15034 features a larger case than its predecessor, measuring approximately 35.8 mm, and introduced thicker, more distinctly faceted lugs. The number 15 in the reference denotes the 15-ligne diameter of the dial. Inside, the watch is powered by a 25-jewel manual-wind movement based on the Seiko Cronos caliber 54A, operating at a steady 18,000 beats per hour. These early models remain highly regarded by collectors for their elegant proportions and significant role in the history of Seiko.
