This model pays tribute to the original Speedmaster, which was born in 1957. This model is a combination of yellow gold and stainless steel and features a two-counter chronograph with coaxial hours and minutes on the totalizer at 3 o'clock, allowing you to read off the elapsed time just like a normal watch.
