This one. Original light brown strap gives it a younger look and its a numbered edition.
Most importantly, for those who find the 42mm hesalite too large, this is 40mm, sapphire crystal, and is less bulky. I have tiny wrists and this fits me just right.
I'm selling this - take a look at the preowned section. Bought it in December 2017 so it still has plenty of warranty from Omega. Like buying new without the new price. Haha
