?? Longines Ultra-Chron | Cal. 6652 | 28,800 BPH | Serviced | Rare Build | 3-Month Warranty ? About My Shop: winebeerglasses Welcome to winebeerglasses, my shop — the same name as my former Etsy store (see my reviews in the last image). ? I proudly maintained a perfect 5-star rating from my buyers on Etsy for five years. I left Etsy due to its poor customer support and migrated to Bonanza. ?

Covered by a 3-month warranty Unlike many “flipped” watches with unknown histories, mine are professionally restored and ready to wear. ?? Don’t get fooled by low prices — those often need $$$ in post-sale servicing. ? No Chinese-made parts used — even the spring bars are Swiss Made. ????? Watch Background: Longines Innovation In the 1970s, Longines was a trailblazer in Swiss watchmaking — akin to Audi in the German auto world at the time. They introduced the revolutionary 431 high-beat movement, running at 36,000 BPH (10 beats/sec), blending precision with durability. Later, they launched the Cal. 6651/6652 — lower beat-rate versions at 28,800 BPH (8 beats/sec). Aside from the escapement and gear train, the design is virtually identical. ? These reduced-rate Ultra-Chrons are actually rarer than their high-beat cousins. ? Watch Details Movement: Longines Cal. 6652 (signed), 28,800 BPH Case: NOS Longines 431 stainless steel uni-body case Bracelet: NOS original Longines stainless steel, fits up to 8" wrist Crystal: New German-made G-S crystal with gold tension ring Crown: Replacement (non-Longines) Dial: Original brown Longines dial — rare color, with some vintage patina Size: 40 mm (excluding crown) 40 mm lug-to-lug Thickness: 13 mm ?

Built by a Watch Hobbyist — Not a Flipper I restore vintage automatic watches as a hobby, applying my background in precision engineering and design aesthetics. Each piece is carefully brought back to full functionality and charm — not just flipped for profit. ?? Vintage Watch Care Not tested for water resistance — keep away from water Handle with care, and enjoy the mechanical soul of vintage watchmaking ?? Warranty Support ? Final sale ? 3-month free maintenance included ? Buyer covers return shipping (if service is needed) ? I’ll repair it and ship it back to you at no extra cost ? Why Vintage? If you’re tired of oversized, cookie-cutter quartz watches, this is your chance to wear something unique and engineered with purpose. The 1960s–70s were the golden age of mechanical design. After that, it all became digital and disposable. ?? Bring back the craft — one wrist at a time.
