Design and Features

The Speedmaster Mark IV features a 42mm stainless steel case with a barrel-like shape, offering a robust and substantial wrist presence. The case is modular, meaning the circular inner case can be removed and swapped with other Omega models from the same era, such as the Speedmaster 125 and the Mark 4.5. This flexibility in design has occasionally led to some unusual and rare configurations appearing on the market, though they are not official prototypes.

The dial is characterized by its functional layout and clarity. It includes a central chronograph seconds hand, a 30-minute counter at 3 o’clock, a 24-hour indicator at 9 o’clock, and a 12-hour counter at 6 o’clock. The black dial, complemented by tritium lume on the indices and hands, ensures excellent readability in various lighting conditions. The mineral glass crystal provides durability and clear visibility of the dial.


At the heart of the Speedmaster Mark IV is the Omega Caliber 1040, Omega’s first automatic chronograph movement. This movement is renowned for its precision and robustness, featuring a 24-hour indicator and a quick-set date function. The Caliber 1040 was a significant innovation at the time, representing Omega’s commitment to advancing chronograph technology.

Historical Context

The Speedmaster Mark series, including the Mark IV, was developed in the wake of the success of the original Speedmaster Professional, commonly known as the “Moonwatch.” The Mark series aimed to offer updated designs and advanced functionalities to meet the evolving needs of professional and recreational users. The Mark IV, in particular, was marketed in 1974 and 1975, alongside the Mark III, rather than as a direct replacement. This parallel marketing approach allowed Omega to cater to different tastes and preferences within the same product line.

The Mark IV’s design reflects the trends of the 1970s, focusing on larger, more robust cases and the inclusion of automatic movements. This model has since gained a dedicated following among collectors for its unique design and historical significance within the Speedmaster lineage.


The Omega Speedmaster Mark IV 176.009 is highly sought after by collectors, particularly those interested in the evolution of the Speedmaster series. Its distinctive design, coupled with the innovative Caliber 1040 movement, makes it a standout piece. Collectors should look for original examples with the correct dial variant (Type H1) and avoid those with service dials, which are distinguishable by the blue 24-hour subdial.

In summary, the Omega Speedmaster Mark IV 176.009 is a remarkable timepiece that captures the spirit of innovation and design of the 1970s. Its robust construction, advanced movement, and distinctive aesthetic make it a prized addition to any collection of vintage chronographs.
