Brand: Seiko Model: Advan Reference Number: 7019-7220 Serial Number: 2N5858 Movement: Automatic Caliber 7019A Dial: Silver sunburst with segmented blue minute track Case Size: 38 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1972 Condition: Good vintage condition Dial and Hands The watch features a dynamic silver sunburst dial that catches the light beautifully, framed by a striking electric blue segmented minute track. The signature red Advan sun logo is positioned above the 6 o'clock marker, providing a vibrant contrast. The applied indices are faceted and polished. A day and date window is located at 3 o'clock, featuring a Kanji day wheel which underscores its Japanese heritage. The hands show visible oxidation and patina consistent with the age of the timepiece, while the dial surface itself remains clean and attractive. The view is distorted characteristically by the original faceted mineral crystal. Case and Crystal The stainless steel case measures 38 mm and presents a sharp, angular profile typical of the "Grammar of Design" influence seen in 1970s Seiko models. The case retains its defined edges and brushed surfaces, showing normal signs of vintage wear such as light scratches but no significant impact marks. The faceted glass crystal, a hallmark of the Advan line, adds depth and complexity to the watch face, showing some surface wear and scratches appropriate for its age. The screw-down caseback clearly displays the reference and serial numbers. Movement Powering this timepiece is the robust Seiko Caliber 7019A automatic movement featuring 21 jewels. Known for its durability and engineering efficiency, this movement offers reliable vintage performance. Timegrapher testing indicates a daily deviation of approximately +45 to +50 seconds, which indicates a functioning movement that is acceptable for a vintage mechanical watch of this era. Strap The watch is fitted with its original stainless steel bracelet, featuring the unique cutout link design specific to this model. It is secured by a deployant clasp signed with the "Seiko Advan" logo. The bracelet accommodates a wrist size of approximately 17.5 cm and complements the angular design of the case perfectly. Condition This timepiece is in good vintage condition. The case is well-preserved with sharp lines, and the dial colors remain vibrant. The primary signs of aging are found on the hands which exhibit oxidation, and the faceted crystal which shows usage marks. Overall, it presents as an honest and original example of 1970s design. Dimensions The case diameter is 38 mm excluding the crown, offering a substantial yet comfortable presence on the wrist that fits well within modern sizing preferences while maintaining vintage charm. Remarks The Seiko Advan series represents a fleeting but impactful moment in horological design where traditional constraints were abandoned for geometric creativity. This reference 7019-7220 is a fantastic entry point into collecting eccentric vintage Seikos, offering a combination of a reliable automatic movement and a conversation-starting aesthetic. History Introduced in the early 1970s, the Advan line was Seiko's answer to the changing tastes of a younger demographic, featuring bold dials, faceted crystals, and unconventional case shapes. The red sun logo is synonymous with this sub-brand, symbolizing a new dawn in watch styling. These models were primarily sold in the Japanese Domestic Market, making them increasingly sought after by international collectors today for their unique place in Seiko's vast lineage. / Second Vintage SKU: SEI-SAN-0002
