Omega’s original Speedmaster, the reference 2915, was the first tool watch to feature a tachymeter scale on the bezel opposed to the dial, which had been the norm for chronograph wristwatches throughout the 1930s, 40s, and 50s. This innovative design would be a game changer and within a few years, it was employed to many brands. First released in 1957, the reference 2915 featured the foundations for all future Speedmaster timepieces, and it is from this lineage the series of reference 2998 was born. Released in 1959, early examples like the present watch used the famed Lemania caliber 321, which is revered amongst watch enthusiasts for its robust chronograph mechanism. The manual wound caliber was used by Omega from 1946-1968, and while small in size at 27mm diameter, it offered optimal performance and reliability.

Early Omega Speedmaster watches are rare in today’s market and when combined with its original unpolished condition, the present chronograph is a collector’s dream. The dial has aged nicely with the lume plots and hands matching in a light yellow hue. The very rare "base 1000" tachymeter has aged beautifully with minor signs of wear – especially difficult to find in such well-preserved condition. Today, the reference 2998 is an icon known for its classic modern aesthetic. The legendary Speedmaster would later be chosen as the watch brought to and worn on the moon, and this early, high quality example offers a great opportunity for the savvy collector.
