Every year Ulysse Nardin brings out a markedly different sub-series of the Blast Open Free Wheel watches. I hear this year it's going to be particularly good. I liked the idea of last year's Marquetry, the technique is fabulous, but the blue and black didn't resonate with me. I thought the diamond version from 2021 was a bit much. I like the Executive black version, but this 2019 version is the essence of this watch.
