Brand: Omega
Typology: Vintage chronograph
Year: 1964

Omega Speedmaster "Pre-Moon" 

The ST105.012 introduced by Omega in 1964, for one major reason: It is THE moon watch, the precise model of Speedmaster that accompanied Buzz Aldrin and Neil Armstrong wore to the moon. Indeed, both their personal watches were ST 105.012s.

In addition, the ST105.012 is the very first Omega to feature the now famous Lyre or twisted lugs, which incorporate guards for both the winding crown and chronograph pushers. It was in also the last of two watches (the other being the 145.012) to feature the world's most famous chronograph caliber, the legendary Caliber 321, based on the Lemania 2310 movement that would still be found more than 40 years later in watches like the Patek Philippe 5070.

This specimen is untouched, unpolished and in absolutely genuine cindiations.

The tritium toning is warm and the gray patina of the background makes it a unique and sought-after object.
