Confused and disappointed - RO 15400ST

[lexrj]

Decided to get a real watch recently and felt in love with the 15400ST in black but never actually tried one until today, I think...
When I tried at the AD today, it looked so much smaller than the pictures and videos on peoples wrists I've seen all over the internet, it was very disappointing...
The price tag on it was $17800 which matches the model and the sales person said it was the 41mm.
Is it possible that I was shown a 37mm or 39mm instead of 41mm with that price tag?
Btw my wrist is 6.75", nothing abnormal.
