This JDM Seiko was bought new from Sakura Watches about a year ago, and is now available to you for a great price without the hassle of international shipping, tariffs, taxes, or anything else! Here are the specs on the watch: * Case size: 39.5mm * Lug to lug: 46mm * Strap width: 20mm * Case thickness: 9.5mm * Movement: [Radio Controlled Solar Powered 7B72](https://www.seikowatches.com/instructions/html/SEIKO_7B62_7B72_EN/index) * Crystal: Sapphire with Super Clear Coating * Water Resistance: 100m * Perpetual Calendar until the year 2100 It's a fun, versatile watch. The Solar Radio Signal works for 5 Areas Around the World (Japan, China, U.S.A., Germany, U.K.), but I am selling to CONUS only. It comes on a Horween leather band, and has the original unworn and unsized Seiko steel bracelet. I am including the original boxes, tags, and cushion. I would say it is in excellent condition. I can't find any obvious marks or scratches, but check the pics to see for yourself. I am happy to answer questions or send any additional media you may want. Price: $240 USD shipped. PayPal please. No trades at this time.

	Established:	1881
	Website:	http://seikousa.com/index.php
	Country of Origin:	Japan

The company was founded in 1881, when Kintarō Hattori opened a watch and jewelry shop called "K. Hattori" (服部時計店 Hattori Tokeiten?) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha (精工舎 Seikōsha?), meaning roughly "House of Exquisite Workmanship". According to Seiko's official company history, titled "A Journey In Time: The Remarkable Story of Seiko" (2003), Seiko is a Japanese word meaning "exquisite" or "success" ("exquisite" is usually written 精巧 from Chinese jīngqiǎo, while the meaning "success" is usually written 成功 from Chinese chénggōng).

Seiko is perhaps best known for its wristwatches, all of which were at one time produced entirely in-house. This includes not only major items such as microgears, motors, hands, crystal oscillators, batteries, sensors, LCDs but also minor items such as the oils used in lubricating the watches and the luminous compounds used on the hands and the dials.
