Condition: Excellent (Grade B) — This exceptional timepiece has just undergone a comprehensive premium overhaul and thorough professional exterior polishing service in July 2026. During this meticulous horological maintenance, critical internal components were replaced. The mainspring, reversing wheel, and caseback plastic gaskets were completely renewed to ensure near-factory operational performance. The technical metrics from the timegrapher are outstanding. It exhibits an exceptional amplitude of 296 degrees, an accuracy rate of plus one second per day, and a perfect beat error of zero point one milliseconds.

The OMEGA Speedmaster Date Reference 3513.50.00 stands as a highly respected automatic chronograph in modern luxury watchmaking history. Housed in a perfectly balanced 39mm stainless steel case layout, this magnificent timepiece features a beautiful deep gloss black dial face. It is complemented by distinct silver accents and a practical date aperture located at the 3 o'clock position. Powered by the reliable OMEGA Caliber 1152 automatic mechanical movement, this watch is built on the world-renowned Valjoux 7750 chronograph architecture. It provides precision timekeeping alongside high-end durability for everyday wear.

The stainless steel bracelet is fitted with all links including two additional spare links. This configuration allows it to comfortably fit substantial wrist sizes up to 20.3cm. This represents a highly desirable feature for international collectors looking for maximum wrist comfort. The sapphire crystal remains completely clean and immaculate with no visible signs of scratches. The case, bezel, and steel bracelet show minor hair scratches and small dings from previous gentle use. The clasp displays medium dings. Please note that the original red OMEGA inner presentation box exhibits typical material flaking due to natural age-related chemical degradation.

This timepiece offers a phenomenal entry point into high-end Swiss watch collection. It gives the owner access to the legendary legacy of the Speedmaster heritage. This is combined with the daily practicality of an automatic date configuration. The dial remains in stunning condition with all luminescent plots fully intact. It is readable under all conditions. Every function, including the chronograph start, stop, and crisp reset mechanisms, operates perfectly in accordance with professional quality control standards.
