Omega Speedmaster Day-Date 39mm – Compact Complexity in a Legendary Line

Model: 3520.50.00 | Serial No. 56073246 | Watch Only

A dynamic evolution of the iconic Moonwatch, the Omega Speedmaster Day-Date (often referred to as the “Triple Date”) delivers Omega’s legendary chronograph heritage in a more compact, function-rich format. At 39mm, this model offers a comfortable and versatile wear, while maintaining a robust and purposeful aesthetic.

The black dial is packed with information—day, date, month, 24-hour indication, and chronograph—yet remains surprisingly legible and well-balanced. Inside beats the Omega Caliber 1151, a reliable automatic movement based on the trusted Valjoux 7751, offering both performance and practicality.
