I dont know if this should be posted in rolex but since it is a tudor i guess so? Anyway i do not have much knowledge and wonder if this is a real tudor?
Not my area of expertise, but from what I do know about Tudors I don't see anything "off" about this one. Not a large watch, probably 32-34mm.
Looks legit. Has an ETA 1182 caliber, probably modified a bit by Rolex. The 7902 is a very small watch, about 29mm.
