An interesting and uncommon Geneve Grand Sport marked dial in metallic blue 166.070 Cal 565

Posting this here, as the dial does look all original and is close enough to the gold-plated examples I’ve seen with “Grand Sport” on the dial, but it’s a metallic blue dial, which I’ve never seen before. It has the telltale damage to the dial at the lume plots which is so common to original blue Omega dial of that time period, the fonts look good, and it sort of makes sense for it to exist, but I can’t even find another Grand Sport marked on the dial in a 166.070 in any color with a steel case, which is why I found it such an interesting data point.

Now I don’t personally thing this watch is worth buying, because of the price, dial damage and frankly it not being that unique despite the rather interesting dial, but I’m curious as to whether anyone else has seen these in steel before and whether a blue one has appeared before.

Here’s the thread about the more commonly known and frankly more attractive checkered flag Grand Sport which is part of the same sort of family:
