A domed acrylic crystal protects the dial, presenting clearly with only minor surface wear that does not impede the view of the watch face.

Dimensions Case Size: 35 mm (excluding the crown) Remarks The Seiko Cronos holds an important place in the brand's history, representing the pinnacle of their thin, manual-wind dress watches of the late 1950s. This example, with its beautifully aged dark dial and reliable Seikosha caliber, offers a compelling opportunity for collectors of vintage Japanese horology to acquire a piece with genuine character and historical significance. History Introduced in 1958 by the Daini Seikosha factory, the Seiko Cronos was designed to be a slimmer, more refined alternative to the Marvel. It featured a completely new movement architecture that allowed for a thinner case profile without sacrificing accuracy or durability. The Cronos line laid the mechanical groundwork for many of Seiko's legendary subsequent models, including the early King Seiko, making it a pivotal stepping stone in the brand's pursuit of elegant design and precision manufacturing during the mid-20th century. / Second Vintage SKU: SEI-SCD-0016
