Hi everyone, Letting go of this vintage Longines Ultra-Chron Chronometer ref. 8353 from around 1973, on its original signed Longines stainless-steel mesh bracelet. If you like 60s – 70s cushion cases, highbeat movements and clean dials, this one hits a sweet spot, wearable, understated, but with that little “ULTRA-CHRON” flair on the dial. The watch was fully serviced by my watchmaker in **September 2025**, so it’s ready to wear and enjoy without worrying about an immediate service bill. **Condition** **Dial:** Original dark grey/charcoal dial in nice condition with even tone. Applied LONGINES winged-hourglass logo, “Automatic Chronometer” text, and Ultra-Chron logo all crisp and well aligned. Hour markers are clean with no noticeable corrosion. **Case:** Stainless-steel cushion case with honest wear from use, light scratches and small marks as expected for age, but the shape is still strong and the lines are present. No obvious signs of heavy polishing to my eye. Screw-back with the Ultra-Chron medallion and reference engravings still clearly visible. **Crown:** Original signed Longines crown with the winged-hourglass logo, operating as it should for winding and time/date setting. **Movement:** High-beat automatic Longines **cal. 431** (36,000 bph) chronometer-rated movement. Fully serviced in **09/2025** (disassembly, cleaning, oiling, regulation). Running well and keeping good time on my wrist. **Bracelet:** Original stainless-steel Longines mesh bracelet with signed clasp and applied gold-tone winged-hourglass logo. Bracelet shows light surface wear but no stretch issues or damage. The clasp has multiple micro-adjust positions so it should fit a range of wrist sizes; in the photos it’s on my medium wrist with room to adjust. **Price: $995 USD shipping included and tariff on my end.** Includes insured worldwide shipping. **Payment & Terms** Payment via Wise, bank transfer, crypto, or PayPal G&S (buyer adds 4.5% to cover fees). As with most private vintage sales, **all sales are final unless I’ve clearly misrepresented something.** I’m happy to provide additional photos or a video on request. **Important note on water resistance** This is a vintage watch that left the factory decades ago. Even though it has been serviced, I treat all vintage pieces as **not waterproof**. Gaskets and seals can only do so much, and these watches were never designed for modern water exposure. Please keep it away from water, humidity, and steam. I have feedback on Reddit and watch forums and am happy to share references via DM. Thanks for looking, and feel free to reach out with any questions.
