Omega Speedmaster Mark IV 176.009

Vintage Omega Speedmaster Automatic Mark IV with Black dial 176.009 from 1973

The Omega Speedmaster Mark IV, reference 176.009, introduced in 1973, is a unique and notable member of the Speedmaster family. This model stands out due to its distinctive cushion-shaped stainless steel case, a design that sets it apart from the classic Speedmaster profile. Often referred to as the “Squircle-Shaped Speedy,” the Mark IV embodies a bold design ethos that was ahead of its time. Brand : Omega Caliber : 1040 Case Diameter : 42mm Case Material : Stainless Steel Dial Color : Black Movement Type : Automatic Time Period : 1970-1979 Dial : Factory Original 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. Movement 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.
