Audace

They are very different watches. I personally would get both. But if you only want to get one, I would say the Diver. The diver is more versatile and can be worn daily if you wish. The safari is a more.. occasion-based kind of watch. Your call, but both are excellent choices! Thing about the safari though is that you might want to invest a little more in getting a HKtan/AP bands (or even an OEM) hornback strap and it will complete the package. The diver is fine with the rubber

Whoops sorry I haven't answered your question. Yup, I got used to my ROO almost immediately. It's a nice feeling, can't really describe it. But yeah, u won't go wrong with a ROO

Not sure about the others, but yes, I agree the diver sits quite high up on your wrist, as do most ROOs. What is the size of your wrist though?
