I was only able to see the hesalite version, looking forward to seeing the sapphire model.
That’s very tasty !
Looking forward to seeing more photos. I’m just considering getting one 🤔
One critical question, regarding the only item I would have preferred different: does the Ω symbol disturb the dial’s matt perfection? I have the feeling this might be the only reason to keep me from getting it. Enjoy!! Alex
The all brushed bracelet is another reason to consider the hesalie, but not a deal maker criterion.
I'm only considering the hesalite version! Fancy fancy!
