даже по поиску в гугле "rolex in sauna" выдает много ответов на форуме положительных. вот например:
I go to the Spa almost daily and my three Oysters follow me (one at a time!).
No problem whatsoever and one of my watches is the Explorer...same TwinLock crown as Datejusts, Dates, Airking, GMT's, etc...
Many regulars there at the Spa do wear these models all the time (over years) and it's fine.
