Omega Speedmaster 125 Chronograph Automatic Full Set

A historically significant and highly distinctive model from Omega; the Speedmaster 125 was introduced in 1973 to commemorate the brand's 125th anniversary. It represents one of the earliest automatic chronograph chronometers ever produced and is powered by the Omega Caliber 1041; the first chronometer-certified automatic chronograph movement offered by the brand.

The watch features a bold; integrated stainless steel case design characteristic of the 1970s; paired with a black tachymeter bezel and a black dial with luminous markers and sub-dials. Its substantial presence and unique case architecture set it apart from traditional Speedmaster models; making it a standout piece within the lineage.

What truly distinguishes this example is its exceptional level of completeness. Vintage Speedmaster 125 models are increasingly difficult to find with their original accessories intact; and examples accompanied by the original box; manuals; and documentation are notably scarce. The survival of these elements together significantly enhances both collectibility and desirability; as most examples on the market today are offered as watch-only.

This level of completeness offers collectors a rare opportunity to acquire a well-preserved example that reflects how the watch would have originally been presented at the time of purchase.
