Info
The Omega Speedmaster Day-Date with reference 3520.50.00, also known as the “Mark 40,” is a distinctive variant of the iconic Speedmaster line, introduced in the 1990s. This model stands out for its full calendar function, displaying the day, date, and month, in addition to the traditional chronograph function. It is powered by the Omega caliber 1151, an automatic movement based on the Valjoux 7751, offering a power reserve of approximately 44 hours.
The stainless steel case has a diameter of 39 mm, slightly more compact than the traditional 42 mm Speedmaster Professional, making it suitable for medium-sized wrists. The black dial features three sub-dials: one for the minute chronograph, one for the hours, and one combined for seconds and the 24-hour indicator. Additionally, the openings at 12 o’clock show the day of the week and the month, while a central hand indicates the date.
This model is appreciated for its functionality and distinctive design, offering a combination of useful complications in a sporty yet elegant timepiece. Although no longer in production, the Omega Speedmaster Day-Date 3520.50.00 remains a popular choice among vintage watch enthusiasts.
