A true dive watch icon, this Omega Seamaster Ploprof Ref. 166.077 remains in its original, unpolished condition with a factory finish. Originally designed for professional divers, this watch was built for extreme underwater conditions and has remained a sought-after piece among collectors. The original blue dial has developed a natural patina, giving it a unique character that speaks to its history. The black Bakelite bezel is exceptionally well-preserved, free from cracks, and still reacts under UV light. Paired with a period-correct Omega mesh bracelet that fits up to a 7.5” (19cm) wrist, this watch retains its original proportions and wearability. While the movement service history is unknown, the watch is currently running well and keeping good time. A fantastic opportunity to own a legendary Omega diver in its original condition. **Reference:** 166.077 **Size:** 42mm **Year:** 1970s 🏞️ [Album](https://imgur.com/a/P1IAkO4) ☑️ [Timestamp](https://imgur.com/a/p9OjktB) 📜 Includes: Custom [travel pouch](https://bogossia.com/products/travel-carrying-case) ($50+ value) 💵 Price: $7,425 + FREE overnight shipping with FedEx fully insured. 🔥 Followers on [Instagram](https://www.instagram.com/bogossiajewelers) get up to $1,000 off based on items price 🔥 📍 Location: New York 🔒 Authenticity: 100% guaranteed, buy with confidence.
