History The Omega Speedmaster Day-Date, frequently referred to by collectors as the triple calendar, was introduced to offer a highly complicated automatic alternative to the traditional manual-wind Professional line. Powered by the robust Caliber 1151, which builds upon a proven Swiss automatic chronograph architecture, this model integrates day, date, month, and 24-hour indicators into a remarkably balanced layout. Produced during the late 1990s, these models have become increasingly appreciated for their mechanical density and versatile proportions.
