Two years ago in the watch shop I compared an Omega Speedmaster with coaxial drive, sapphire crystal and metal bracelet with my simple 2002 Speedmaster Professional with manual winding and Hesalite crystal. I like my simple Professional better, but that is a matter of taste. I like the simple original style. The Hesalite watch is also lighter which I appreciate. I have a 2004 Broad Arrow with sapphire crystal, but it is creamy white. There the glass looks ok and the weight is also ok because it has a thin leather strap. On a black Speedmaster the sapphire crystal would always bother me no matter how rare or exclusive the model type is.
In the video below you can see very clearly what I mean.
It is a very significant difference for me in nature, not only visually but also emotionally. You have to see the Hesalite watch in real life. BTW slight scratches disappear by themselves when wearing a shirt sleeve over the watch. In addition it occurs to me that the Hesalite Speedmaster fits in its philosophy very well to a 4/4
