Seiko Bell-Matic – Jumbo Case – Rare Blue Dial – Mechanical Alarm – 1970s A time capsule from the golden era of Japanese watchmaking — this stunning Seiko Bell-Matic is more than just a watch; it’s a mechanical marvel with a voice of its own. This is the rare jumbo-case version with the highly sought-after deep blue sunburst dial, a color that rarely appears on the market — and almost never in this exceptional condition. The vibrant blue face, accented with turquoise minute markers and crisp white indices, radiates 1970s charm. It’s bold, clean, and eye-catching — a true vintage statement. Everything works exactly as it should. The fully serviced mechanical movement powers the watch smoothly, and the mechanical alarm function is working perfectly — it’s loud, crisp, and satisfying. A true collector’s delight. The stainless steel case remains sharp, unpolished, and honest — preserving its vintage character. The original Seiko bracelet fits wrists up to 19cm, making it ideal for most collectors. There is one minor detail worth noting: a tiny crack on the edge of the original glass. It’s very small and barely noticeable when worn — and because the rest of the glass is so beautifully preserved with no scratches, it was left untouched for originality. ⸻ Highlights: • Rare Blue Dial – Excellent Condition - French Day Wheel • Jumbo Case Version – Hard to Find, Especially Like This • Fully Working Mechanical Alarm – Loud and Perfect • Original Glass with Tiny, Barely Visible Crack – Left Untouched for Authenticity • Serviced and Ready to Wear • Original Bracelet – Fits Up to 19cm Wrist • No Box or Papers ⸻ This is not a watch you come across often — especially not in this condition.
