Seller: magistertempli (665) 100%, Location: Tonganoxie, Kansas, Ships to: Worldwide, Item: 283611950912 1930s SEIKOSHA (early Seiko)Uranium Glass ClockPristine Dial and CaseRunning Great and Keeping Time U.S. SELLER This is a "Buy It Now" Listing From my personal collection: Seikosha, now known as Seiko Time Corp., was founded in 1881 by Kintaro Hattori in the Ginza District of Chuo-ku, Tokyo, Japan, and was was registered as a corporation in 1917. Seikosha began making clocks in 1902 and continued using the trademarked "S" within a circle and a diamond logo on their dials until the late 1930s or early 1940s. Uranium glass was invented in the early 1800s and reached the peak of its popularity from 1880 until World War I, and continued to be made until World War II interrupted production. Uranium glass fluoresces or glows green under ultraviolet light. Although I do not have the right lighting and photographic equipment to capture an image of this effect, I have seen these old green glass Seikosha clocks go for as much as $250 here on Ebay just because someone was able to show them glowing in a darkened room under a black light. No caliber number or other information is available about the particular movement in this Seikosha. By the time this one was made, however, Seikosha was an entirely in-house operation. This is significant because, just a few years earlier, most Seikosha pocket watches and wall clocks contained movements sourced from Europe and America. Seikosha's technical achievements paralleled the advancement of the country as a whole at a time when Japan was considered the world's fifth leading power. Measures 75 mm square (width and height,) and 50 mm thick from front to back. Weight: 1 lb. 2.2 oz., or aprox. 516 gm. Around the edge of the dial at the bottom, in small print, is inscribed, "MADE BY SEIKOSHA, TOKYO, JAPAN." Seiko has continued to this day with a company custom of using a microprint at the bottom of even wristwatches to identify the country of manufacture and the movement caliber number. In excellent vintage for a clock at least 80 to 90 years old. RUNNING AND KEEPING TIME. Glass in unbelievably great shape with sharp corners and no chips or scratches. THE DIAL IS ABSOLUTELY PERFECT. The yellow seen at the edges of the dial (photo #1) is a reflection from a gold-colored metallic retainer ring beneath the glass, and is NOT on the dial. The yellow seen in the middle of the dial is a gold colored metallic grommet and, again, NOT discoloration of the dial. (The ring itself can be seen in Photo #2.) Light brassing of the bezel in a few spots toward the top. These areas are greatly exaggerated by these brightly lit and highly magnified photos. The imperfections toward the bottom of the bezel are faint enough that they do not show at actual size in average indoor light. A bit of wear from abrasion to the underside of the glass case, where it does not show when the clock is standing upright. One original brass nut has been replaced with a plated one, (see Photo #8). This is a super piece for both the Seiko or Seikosha enthusiast as well as the uranium glass collector. These are offered on Ebay once in a blue moon, and it's rarer still to see one in this condition. Nearly all others that I have ever seen have had chips. Of course I will miss it, but I have made a firm decision to rationalize my collections. In short, I simply can no longer keep them all. Returns in the same condition as when shipped cheerfully accepted for 30 days. Buyer pays the postage unless the item is not as described.
