Timeless Everyday Luxury: The Serviced Omega Seamaster 120m Blue Dial 2511.81

The Omega Seamaster series is legendary, renowned for its robust diving heritage. However, the Seamaster 120m offers a more refined, versatile alternative that seamlessly transitions from professional settings to casual weekends. Today, we present a beautiful example: the Omega Seamaster 120m Reference 2511.81, featuring a stunning blue wave dial and a practical Swiss quartz movement. This pre-owned luxury watch has been meticulously serviced and is ready for its next owner.

Classic Specs and Enduring Design

Crafted from durable 316L stainless steel, the case measures a versatile 36mm in diameter (excluding the crown) by 43mm lug-to-lug, with a slim 10mm thickness. This "mid-size" footprint ensures an exceptionally comfortable fit on a variety of wrist sizes and slips easily under a shirt cuff. The iconic blue dial, protected by a scratch-resistant sapphire glass, displays a subtle wave pattern that catches the light beautifully, evoking the ocean spirit of the Seamaster line.

Reliable Swiss Quartz and Honest Condition Report

Inside beats a reliable Swiss precision quartz movement, offering "grab-and-go" convenience and superior accuracy without the need for regular winding. We have assigned this watch a Grade AB (Excellent Condition) assessment.

To provide absolute peace of mind, it has just completed a comprehensive service on March 9, 2026, which included professional polishing, ultrasonic cleaning, battery replacement, new gaskets, and a successful waterproof test. While the crystal, case, and bracelet are in beautiful condition, we honestly disclose minor scratches on the bezel, small scuffs on the hands, and a minute particle inside the dial—details that reflect its authentic history without detractly from its stunning wrist presence.
