Start with the wrist, not the advertisement. Rest the case on the flat of the arm and see whether the lugs stop before the wrist bends. If they hang over the edge, the watch will rock when the hand moves. If they stop short, the piece can feel smaller than its diameter. Then check the underside. The clasp should lie in the center, not on the bone. Press the first link where it leaves the case. A smooth curve is what you want. A sharp kink means the end link is fighting the lug. Write those two observations before you look at the dial, because the dial is what photographs well and the wrist is what you live with.
How it differs
For the Bvlgari, compare the diameter you can measure with the length from lug tip to lug tip. A wide bezel can make the dial look smaller than the case. Keep the comparison inside this case idea.
Common mods
On the Bvlgari, people change the insert, the bracelet, or the hand set. Name the one part that was changed and leave the rest undescribed rather than guessing.
What to check on a used piece
Check the clasp position, the end-link gap, and whether the hands pass cleanly on the Bvlgari. Write those three and ignore the sales line. These notes are not authentication and not a shop.
