Question About 1978 Rolex 18039

[dcannata4]

Recently picked up a Rolex 18039 but am concerned about the bracelet fitted to the watch. Everything seems perfect. Can find the head of the lady of helvetia on the lug with the g. Looks legit. Even the bracelet engravings on the clasp look perfect minus missing the St bernard or the lady stamp. I can only find 2 or 3 other examples online that do not have these markings which is why I am concerned. Does anyone have any information on this?
