Hi thxs for your comment what is IoR?In my opinion its a little bit strange when it comes to functionality..
Normalky you would try to install a small crown on a dresser to prevent it from either to bite in your wrist or your cloth.
Next is that the complex crystal geometry at least in case that you would like a higher grade then glass would make it difficult to get that thing water tight
The domed geomtry would affect the bezel by the IoR when it comes to readability
I think its a nice rendering but still far from being a proposal for a real watch ..
