Seiko Silver Wave 2906-0180 Developed by Seiko throughout the 1970s, the Silver Wave series holds a special place among the brand's highly water-resistant sporty models offered before its transition to professional diving watches. This example is one of the rarer references in the series, distinguished by its technical features.
The stainless steel case reflects the characteristic robust form of the era, while the screw-down crown supports the high water resistance, a key feature of the Silver Wave series. This detail demonstrates that the watch was designed not only aesthetically but also functionally for a purpose superior to its time.
The silver-toned dial is simple, balanced, and highly legible. At the 2 o'clock position, there is an extremely small mark that is only noticeable upon very close inspection; it is absolutely inconspicuous during daily use or on the wrist. Overall condition is quite good considering the year of manufacture.
Inside the watch is Seiko's reliable automatic Cal. 2906 movement. This movement, which forms the technical basis of the Silver Wave series, is known for its robust construction and long-lasting use.
The serial number 745252 on the case back clearly confirms that the watch was manufactured in 1977 according to Seiko's production coding.
