I've got mine through an Omega boutique in Switzerland.
My first impressions after the first day:
- It's huge, it's massive, it's a beast
- It's heavy (240g with 3,5 links removed)
- It's thick
- BUT: it wears phenomenally comfortable despite being so heavy (I have 18,5 cm / 7,08 inch wrist). I don't have the feeling that I'm weight-lifting. Omega has done an outstanding job by making this watch so wearable. This is probably the most impressive feature of this watch.
- I wear the bracelet a bit tighter than usual (so the heavy watch does not move around too much on the wrist)
- The new clasp is just wow (it's not wider or higher than the bracelet itself. great job here)
- The O-Megasteel and the ceramic bezel are not too shiny, not too bling-bling
- The dial is relatively small compared to other watches in my collection
- Build quality is outstanding
Long story short: An awesome watch.
