Important Notice: This 'NOS' authentic, discontinued timepiece is unworn inventory that has remained in storage for a prolonged period and is not equivalent to a factory-fresh modern retail watch. Due to age and historical handling, the item may exhibit "storage wear" such as fine hairline scratches or minor abrasions. Buyers should note that internal lubricants may have dried or gaskets degraded, so a professional service and pressure test are recommended to ensure optimal performance.
Released as part of the 55th anniversary collection, this reference draws its design from the 6119-6050 Regatta Timer. Seiko revived the historical dial layout by integrating a multicolored inner chapter ring and an updated bezel insert, because the brand aimed to modernize the original 1969 release.
The 43mm stainless steel case utilizes the standard SKX-style profile to house the caliber 4R36 movement, which operates with a 41-hour power reserve. This mechanism includes manual winding and hacking capabilities, while a transparent caseback displays the internals of the caliber.
Established in 1881 by Kintarō Hattori, Seiko is defined by its principle of complete vertical integration, manufacturing every single component of its timepieces in-house. They were the primary catalyst of the "Quartz Crisis" with the commercial release of the 1969 Astron—the world’s first quartz watch—the brand simultaneously advanced mechanical horology, developing one of the first automatic chronographs and pioneering high-frequency movements to challenge Swiss standards.
Seiko's relentless innovation continues with proprietary technologies like Spring Drive, which blends mechanical power with quartz precision. This technical mastery underpins Seiko's legacy in creating archetypal and exceptionally durable tool watches, particularly in the domain of professional diving.
