High quality fakes cannot be given the

with the picture quality given here.
1. Need accurate weight.
2. Need
accurate dimension against known genuine example.
3. Check for ring tone, if different alloy, (not needed if access to XRF instrument available).
4. Close comparative visual inspection of all design details, against known genuine example.
5. Inspection and comparison of edge milling.
6. 20X inspection of the surface against known genuine example, checking particularly for high pressure casting.
If any doubt, leave well alone.
I have even seen good quality silver fakes, where the genuine is in copper nickel.
