Seiko Spirit SBTM170 & SSDT050 - 2012 | NOS (New Old Stock), Full Set
On these two Seiko Spirit models, the light-colored dials shift in tone from silver to cream and pale champagne depending on the angle of the light. The faceted surfaces of the gold-tone indices stand out against a pearlescent luster created by a fine, sunray-brushed texture. This same warm metallic tone is echoed in the pointed hour and minute hands, the broad bezels, and the crowns.
**IMPORTANT NOTE: As this item is shipped from within the European Union, you will not be liable for any intra-EU customs duties.**
The men’s model (SBTM170) and the women’s model (SSDT050) share a common design language, scaled to different dimensions: the SBTM170 features a case diameter of approximately 37.6 mm, while the SSDT050 measures 28 mm. The date window, positioned at 3 o’clock on the men’s model, is absent on the women’s version, allowing for the inclusion of all twelve hour indices on the smaller dial. Both models are protected by sapphire crystals.
On the stainless steel cases, the brushed upper surfaces of the lugs contrast with the polished bezels and case sides. Beyond the gold-tone bezel frames, the bracelets are finished entirely in steel. The three-link design featuring wide center links accented by polished transitions remains consistent across both sizes. The bracelets are secured with push-button folding clasps, each signed by Seiko.
Beneath their classic exteriors, both watches are powered by light-driven quartz movements: the Seiko 7B52 in the SBTM170, and the Seiko 3B51 in the SSDT050. Light passing through the dial is converted into electrical energy by a solar cell located beneath it and stored in a rechargeable cell. According to Seiko’s technical specifications, both calibers offer an operating duration of approximately six months on a full charge; an energy-saving function can further extend this period.
The radio-controlled feature corrects the time by receiving standard time signals from Japan. Small markings around the dial allow the second hand to indicate signal strength and the outcome of the reception process. Developed specifically for Japan, this system cannot receive corresponding radio signals within the EU. The watches can also be set manually and continue to function as standard solar-powered quartz timepieces.
The SBTM170 (serial number 292561) was manufactured in September 2012, while the SSDT050 (serial number 262000) dates from June 2012. The Japanese-language warranty documents, which correspond to the serial numbers of both watches, indicate a date of sale of March 8, 2014.
