Rare Seiko S603-00A0 Super Runners Digital Alarm Chronograph, Bold Yellow Case, Black Rubber Strap, 10 Bar Water Resist, Running Few vintage Seiko digitals command attention quite like the Super Runners series, and this S603-00A0 in striking yellow and black is one of the most visually arresting examples you will find. Produced by Seiko during the peak of the Japanese sports watch boom, the Super Runners line was purpose-built for serious athletic use — and this example brings all of that performance heritage to the collector's wrist in a package that looks as energetic today as the day it was made. The dial is clean and fully active, displaying day, date, and time with crisp LCD legibility. Function labels are molded directly into the bright yellow bezel — Display Chg., Start/Stop, Mode/Adjust, Light, and Lap/Reset — a practical, purpose-first design that makes every function instantly accessible without hunting for tiny unmarked pushers. The prominent white Lap/Reset bar button at the six o'clock position is a signature Super Runners design element that is immediately recognizable to enthusiasts of Japanese sport digital watches. The Seiko logo is cleanly printed at twelve o'clock on the inner bezel ring. The case back is engraved with reference S603-00A0, "Water Resistant 10 Bar," "Made in China," and serial number 380073 — confirming genuine Seiko provenance and serious water resistance rated to 100 meters. The case measures 45.5mm wide and 15.8mm thick as confirmed by caliper, with four color-coded pushers — two white and two black — flanking the yellow case sides for intuitive one-handed operation. The original black rubber strap with perforated ventilation holes is stamped "Seiko" on the clasp and fits a wrist of approximately 7 inches as shown on the sizing cone. Condition The overall condition of this watch is very good to excellent for a vintage sport digital. The yellow case presents boldly with vibrant color retention and no significant fading or cracking — the resin has held up exceptionally well. The LCD is fully functional with all segments displaying correctly and no dead pixels observed. The white Lap/Reset button and black Mode/Adjust buttons are all intact and retain their color without yellowing. Light surface marks are present on the case sides consistent with careful use, including a faint surface scratch visible on the left case side in the close-up photos — noted honestly for full transparency. The black rubber strap is supple and intact with no cracking, and the Seiko-stamped clasp operates correctly. The case back shows normal brushed wear. This is a very presentable, fully working example of a collectible Seiko sports digital that is genuinely difficult to find in this condition. Shipping is same day or 1 business day. This watch has been photographed extensively and videoed prior to shipment. #Seiko, #SeikоSuperRunners, #S60300A0, #SuperRunners, #VintageSeiko, #SeikоDigital, #JapaneseSportsWatch, #VintageDigitalWatch, #SeikоChronograph, #AlarmChronograph, #10BarWaterResist, #YellowWatch, #RetroSportsWatch, #VintageWatchCollector, #LapTimer, #RunningWatch, #SeikоJapan, #WatchCollecting, #DigitalWatch #WatchesOfEbay All listings are AS-IS. I have made every effort possible to describe the item in this listing accurately. All the items I sell are authentic and in working order unless otherwise noted as parts. By bidding on this item, you completely accept these terms. I pack items I sell extremely well. I make no statement whatsoever about support for watch function after the item has left my warehouse. In addition, every watch that I list on eBay has been photographed extensively and been videoed. This means that once the watch leaves my warehouse, it is in the same identical shape as described in the listing. I will not take back a watch and return especially one that has been tampered with previously nor falsely declaring that a watch is not working, when the proof says otherwise. Do not leave negative feedback as a means of leverage over me. I will willingly work with every buyer to assist with issues that arise, or if by chance a 30- or 40-year old vintage watch decided to be unstable. If you choose to leave negative feedback as a means of gaining leverage over me to mischaracterize the accuracy of the listing, you will face overwhelming proof on my side that the item listed was in the shape as described in the description and I WILL CONTACT eBAY WITH OVERWHELMING PROOF THAT THE ITEM WAS ACCURATELY DESCRIBED AT THE TIME OF THE LISTING.
