Produced in July 1971, the reference 7017-8000 is a highly sought-after JDM (Japanese Domestic Market) classic that perfectly captures the bold, adventurous spirit of 1970s horology.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eWhat makes the 7017 caliber so special is its brilliantly clean layout. Unlike traditional chronographs, it features no sub-dials, offering a sleek, uncluttered aesthetic while still functioning as a highly capable \"flyback\" chronograph. The deep charcoal dial is brought to life by striking orange accents, including the sweeping central chronograph hand, the iconic \"Speed-Timer\" text, and the rare inner Pulsimeter scale used originally by doctors and athletes to measure heart rates. Housed in a robust 41mm stainless steel cushion case, this watch commands attention on the wrist. To complete the restoration, a brand-new crystal has been installed, offering a flawless, unobstructed view of this stunning dial. Furthermore, this piece is fitted with its original stainless steel bracelet. Finding these vintage Seiko models with their original bracelets intact and in such great condition is increasingly rare, making this a truly exceptional find for collectors.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eThe Value of a Fully Serviced Chronograph\u003c\/strong\u003e\u003cbr\u003eVintage mechanical chronographs are notoriously complex, and buying an unserviced piece usually means anticipating an expensive and lengthy trip to the watchmaker. This timepiece, however, has been newly and thoroughly overhauled.\u003cbr\u003eThe entire movement has been completely dismantled, carefully cleaned, freshly lubricated, and precisely regulated. The automatic winding, quickset day\/date, and the intricate flyback chronograph functions all perform flawlessly. By purchasing a freshly serviced watch, you are saving hundreds of euros in specialized service fees and months of waiting time. This premium condition is factored into the value of the watch, ensuring that you are investing in a timepiece that is entirely free of hidden issues and ready to be enjoyed straight out of the box.\u003cbr\u003eSpecifications\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Seiko\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 5 Sports Speed-Timer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 7017-8000\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial Number:\u003c\/strong\u003e 173532 (Produced July 1971)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Caliber 7017, Automatic Flyback Chronograph\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Charcoal\/Black with orange accents and inner Pulsimeter (Base 15) scale\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Brand-new crystal installed\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Stainless Steel (Tonneau\/Cushion shape)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e 41mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplications:\u003c\/strong\u003e Flyback Chronograph, Quickset Day (English\/Kanji) and Date\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet:\u003c\/strong\u003e 18,5cm, Rare, original stainless steel bracelet in great condition\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUser Guide \u0026amp; Important Notes\u003c\/strong\u003e\u003cbr\u003eHow to use the Pulsimeter (Base 15)\u003cbr\u003eThe inner chapter ring features a \"Pulsimeter Base 15\" scale, a fascinating tool originally designed for medical professionals and athletes.

In fact, many watchmakers argue that leaving a vertical clutch running relieves tension on the clutch spring. You are perfectly safe to leave it sweeping all day if you enjoy the visual motion, or you can leave it reset at the 12 o'clock position to slightly extend the watch's power reserve.
