Hello,
Nikon HG 10x42 in the 1000e class (850 lire) is the best option in my opinion for you. It ticks all your requirements (money, weight and 10x42). It has large FOV and beautiful colours, with clarity over the entire FOV. And, in my opinion, the most beautiful compact roof binoculars. Nikon HG already slightly exceeds your desired budget, but not by much. Of course, If you are willing to pay double or triple, you have several better 10x42 variants, Zeiss Victory SF, Leica Noctivid, Leica Ultravid, Swaro Nl Pure, Nikon EDG, Zeiss SFL... with a slightly heavier weight (but with bino harness are great). But let's not get into unnecessary discussions, and focus on your requirment: under 1000 euros or a little over, relatively reduced weight and 10x42.
If you are willing to pay a little more (aprox. 1150 euros), here are some of the best options in this price range:
Swaro Habicht 10x40 is extremely good, maybe the best in the 1150ron sector. Its main quality is the transmission of light (even better than binoculars 3 times more expensive!!!) But be careful! It has a small eye relief of only 13mm, making it more uncomfortable and unusable for those who wear glasses.
Zeiss Conquest 10x42 is a bit heavier but it is optically excellent, especially for the image resolution
Leica Trinovid 10x42, has a smaller FOV but has an image that you may like a lot, thanks to the pleasant and calming colors. My opinion is that these are the variants that are close to your initial requirements.
