Reference 3513.50.00 represents the Speedmaster in its quintessential form — a 39mm round stainless steel case anchored by a tachymetric scale bezel and secured with a screw-down crown. The black dial pairs index hour markers with luminescent hands for clear readability, while the sapphire crystal provides reliable scratch resistance. Chronograph, date, and tachymeter functionality round out the feature set.
Power comes from the Omega Caliber 1152, an automatic movement that drives the chronograph complication with the precision the Speedmaster name is known for. The watch rides on a stainless steel bracelet fastened by a sliding clasp, and carries a water resistance rating of 50 meters / 165 feet — suited for everyday wear.
This is a used example in factory configuration, offered without the original box or papers. Swiss Made and bearing the hallmarks of Omega's enduring chronograph heritage, it makes a compelling choice for the collector or daily wearer alike.
