Omega Seamaster Professional 300M Electric Blue Full Set

• COSC-certified chronometer, Omega caliber 1120 automatic • Full set: original Omega red presentation box, outer box, chronometer certificate, pictogram card, and operating instructions booklet • Matching numbers — serial on the chronometer certificate matches the engraving on the case • Single-family ownership from an estate; sat safely stored for years • Scalloped steel dive bezel, helium escape valve, 300m water resistance rating, sapphire crystal • Speedmaster-style brushed steel bracelet with signed Seamaster Professional clasp Condition: Honest, original, and unpolished. Case edges remain sharp with factory brushing. Light wear consistent with age; dial and hands are clean with strong, even lume. Movement runs strong and keeps time well; date changes crisply. Sold as an unpolished, original example — increasingly rare for this reference, as many on the market have been polished or refinished. The 2253.80 is discontinued with fixed supply, and full sets with matching papers rarely come up. This is the sweet spot of early-2000s Omega: slim, versatile proportions before the modern cases grew thicker, with a dial you won’t find anywhere else in the Seamaster lineup. Serious inquiries welcome; additional photos and video available on request.
