The dial is framed by an internal minute track and the watch's signature fluted bezel, which remains crisp and distinct. Case and Crystal The stainless steel case measures a substantial 38mm, offering a modern presence on the wrist while maintaining vintage proportions. The case geometry is defined by the unique hidden crown at the 4 o'clock position and a dedicated date-push button at 2 o'clock. The lugs are thick and retain their original definition. The external fluted bezel is sharp with minimal wear, serving as a focal point of the design. The crystal is clear and presents well, allowing for an unobstructed view of the dial. The caseback features the iconic "Dolphin" engraving, which is deeply etched and clearly visible, along with the serial and reference numbers.

Dimensions The case diameter is 38mm excluding the hidden crown, with a lug-to-lug length that ensures a comfortable fit on a variety of wrist sizes. The lug width accommodates standard vintage strap sizes. Remarks The Sportsmatic Deluxe reference 7606-7000 is a standout model that bridges the gap between the robust utility of the Seiko 5 line and the elegance of dress watches. The combination of the Kanji day wheel, the "Deluxe" specification, and the fluted bezel makes this a particularly attractive variation. History Introduced in the 1960s, the Sportsmatic line was pivotal in establishing Seiko's dominance in the automatic watch market. The "Deluxe" variants were positioned higher than the standard models, featuring higher jewel counts and improved finishing. The Dolphin icon on the caseback signifies the watch's water-resistant capabilities, a major selling point at the time. This specific model, produced in May 1965, captures the essence of Seiko's "Grammar of Design" era just as it was beginning to take shape. / Second Vintage SKU: SEI-SSD-0036
