Bulgari did a great job with this watch. It is 40mm in size and only 5.1mm thick. Most thin watches with larger diameters have a awkward fit on the wrist, but the flowing bracelet design somehow makes this sit well.
I like the fact that this watch invites daily use just given the great combination of thinness, light weight and a sandblasted finish that just seems like it will take daily brushes and knocks better than highly complex polished surfaces like a Nautilus or AP Jumbo. It also remarkably feels quite rigid for a thin watch.
Notice the cutouts in the links next to the clasp, so it sits flush with the bracelet when closed.
Which makes for a nice smooth profile.
Bulgari put a lot of thought into this design and developed an innovative ultra-thin in their own unique vision. I consider this to be a breakthrough design which they need to shepherd well into an icon by not modifying it too frequently.
