Its standout feature is a manually operated perpetual-style calendar, integrated into a distinctive dial design. \u003c\/p\u003e\n\u003cp\u003eThe Advan line was developed for younger Japanese buyers, emphasizing modern, unconventional designs rather than traditional dress-watch styling.\u003c\/p\u003e\n\u003cp\u003eThe 7019-6050 was produced around 1972–1973, with documented examples from both years. It is particularly interesting because it combines a conventional automatic day-date movement with a separate calendar calculation system.\u003c\/p\u003e\n\u003cp\u003eUnlike a mechanical perpetual calendar, the 7019-6050 uses a manually adjustable rotating ring to display the relationship between dates and weekdays throughout a month.\u003c\/p\u003e\n\u003cp\u003eThe dial has a date scale from 1 to 31 around its perimeter, while the rotating inner ring displays the weekdays.\u003c\/p\u003e\n\u003cp\u003eThe crown at 2 o'clock adjusts this calendar ring. By aligning the weekday with the first day of the month, you can determine the weekday corresponding to any date that month.\u003c\/p\u003e\n\u003cp\u003eThe crown at 4 o'clock operates the conventional movement functions, including time and day-date adjustment.\u003c\/p\u003e\n\u003cp\u003eImportantly, the calendar ring does not advance automatically. It is a manual calendar calculator rather than a true mechanical perpetual-calendar complicatin.\u003c\/p\u003e\n\u003cp\u003eBrown dial is spectacular and flawless. \u003c\/p\u003e\n\u003cp\u003eCase is in pretty good condition, sharp with some minor nicks here and there. \u003c\/p\u003e\n\u003cp\u003eOriginal stainless steel bracelet is in very good condition. It's fits 18.5cm wrist comfortably. \u003c\/p\u003e\n\u003cp\u003eCompletely disassembled, cleaned, lubricated and regulated. \u003c\/p\u003e\n\u003cp\u003eMovement is shiny and clean and runs strong with good accuracy. \u003c\/p\u003e\n\u003cp\u003ePull the crown one step to change date and push it to change weekday. Weekdays are in English and Kanji. \u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eSKU#\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003eS2265\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003e7019-6050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eMovement\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003eautomatic \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eCaliber\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003e7019A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eJewels\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003e21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eCase\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003eStainless steel \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eCase size\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003e39mm x 40mm \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eLugs\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003e20mm \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eDial\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003ebrown \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eCrystal\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003eNOS Seiko hardlex \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eBracelet\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003eoriginal stainless steel 19cm \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eSerial #\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003e315301\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.8366%;\"\u003eService\u003c\/td\u003e\n\u003ctd style=\"width: 60.1634%;\"\u003eOct 28, 2026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c!-- ================================ --\u003e","brand":"TokeiMedic","offers":[{"title":"Default Title","offer_id":50846628643013,"sku":"S2265","price":108000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/0885\/0885\/files\/PSX_20261030_215243.jpg?v=1793371314","url":"https:\/\/tokeimedic.com\/products\/1973-seiko-advan-7019-6050","provider":"TokeiMedic ","version":"1.0","type":"link"}
