Opus V Rose Gold
One could argue this is the single most important watch of the modern era. Not only did it play a pivotal role in the rise of both MB&F and URWERK, but if you look at the watches that came before it and those which came after, it clearly influenced the entire sphere of contemporary horology.
This is the rose gold piece which is considered to be the more wearable of the two as the platinum is very heavy. It was a limited edition of 45. It was factory serviced in 2018 and has barely been worn since.
