Seiko Liner Chronometer ref. 46999 Manual Winding Seiko's highly accurate "Liner Chronometer" model. Featuring the Cal. 460 with 25 jewels, this is a very rare model that was awarded the title only to those that passed the strict chronometer standards within Seiko at the time. It is a highly sought-after model among collectors as it laid the foundation for high-end domestic watches before the birth of Grand Seiko. The production period was reportedly about one year. It has the original "W SEIKO" crown. However, the medallion on the back cover is missing. The leather strap and buckle are aftermarket. I believe I purchased this as a vintage item from a local watch shop about 15 years ago. My memory is vague, but I had it overhauled about 7 years ago. At that time, the crystal and crown were replaced with new ones. After the overhaul, I hardly used it and kept it in storage. Since it has been a number of years, those who intend to use it should have it overhauled. To prevent swapping, we do not accept returns under any circumstances. Thank you for your understanding. Please refrain from purchasing if you are sensitive to the condition of antique or vintage items. #GrandSeiko #Liner #46999 #44KS #45KS #52KS #56KS #44GS #45GS #57GS #61GS
