I think that both would look less bold with different straps, though we all know that these watches are just toys the the masses 😎 (which is a plus nowadays).
I didn't try these ones at the last Milano watch week but I'd be curious to look at the violet with real light.
The light speed is more classic in terms of materials, that's why I'd go for the ultraviolet (with a dark strap, too).🤩🤩
Anyway whatever you choose you have my respect, much better than the Hublot 👍
