Dimensions Case Size: 39 mm (excluding the crown) Wrist Size: 18 cm Remarks The Speedmaster Day-Date, often referred to by collectors as the Mk40 series, represents a highly successful era of Omega’s design language where utility and style seamlessly converged. The blue dial variant is particularly coveted for its dynamic appearance, offering a slightly more elegant alternative to the traditional matte black Speedmaster aesthetic while sacrificing none of the model's inherent sporting character. History Introduced as an evolution of the Speedmaster Automatic line, the Day-Date models were designed to offer the everyday convenience of self-winding movements combined with the highly practical calendar functions. While the Speedmaster Professional maintained its manual-wind legacy in space, the automatic variations were aimed at earth-bound professionals who required a reliable, multi-functional, and sophisticated daily wearer. Today, these neo-vintage models are celebrated for their perfect proportions and mechanical density, cementing their place as a vital chapter in the enduring Speedmaster story.
