Sports watch that scratches easily?
Not a good thing to hear, at these kinds of prices. And I understand coatings cannot be repaired nor polished.
Andrew's article on the RM035 here says:
" ... the alloy is coated with magnesium and aluminium crystalline oxide ceramic (otherwise called ‘spinels’). The spinels are actually a naturally occurring phenomenon in various semi-precious rocks; however, a synthetic form is used on surfaces such as the RM035 case. What makes the surface so resistant to corrosion and wear, as well as being biocompatible comes from the lattice structure of the oxides themselves. The actual formula: MgAl2O4 tells a story. It tells the story that if the ions per oxide are smaller for one part of the lattice structure than another part, then the smaller part can occupy the holes between molecules because of a charge factor. This maximises the lattice energy if the ions are similar in size and creates a regular lattice for the molecular structure. Such bonding makes the surface of the crystalline oxide ceramic very tough and inert: there is no spare positive or negative charge. To give the toughness of the crystalline oxide ceramic some form of number, the coating ranks approximately an 8 on the Mohs scale; which approximately corresponds (as the scales are not strictly comparable) to a 1800 – 2000 Vickers. In short, a lot tougher than most steels and hence, not easily scratched (although not impossible either). "
I understand from this that the Nadal RM035 case should be pretty resistant against most accidental brushes against hard surfaces but not against hard knocks.
I wonder if this assumption is correct?

Just wondering if anyone has pertinent thoughts about the relative durability of these two watches' cases? I do realise there are precious few who have any experience of either case.. I was thinking along the lines of resistance to scratches and more extr...
Can you show pics ?
Would appreciate it, hta. Very curious about the long-term scratch-resistance of the 35... Thanks Rob
