Hey guys hope you all are doing great. today I am here with another beautiful timepiece so called Seiko automatic it's a 90's article of Seiko which is totally a Japanese made watch What's special about the movement? The 4S15 was a high-end movement, adjusted to +15/-10 seconds per day from the factory. This is nearly as accurate as the "Top" grade ETA 2892 and similar movements. It features a thermo- compensating balance and hairspring, and the movement hacks. A nearly-identical movement, Cal. 4871, was used in Credor watches and is gold plated. A less-adjusted movement, the 4815, appeared later and is the most common of the family. This family is also used in alpinist, king Seiko etc. overall condition of the watch is great, the watch is perfect in timekeeping. This is One of my favorite from my collection hope you will like it Movement: Seiko 4S15 automatic, 25 jewels, 28,800 bph Quickset date Automatic Dimensions: Diameter 36mm excluding crown Thickness 8mm Lug width 19mm Reference number 4s15-8030 Textured Dial Strap aftermarket stainless Steel back Serial number 390525 Condition good Working perfect
