Twin lock crown reliability....

[Verydark]

Hello, i´m thinking about the purchase of a Datejust soon and i was wondering about twin lock crown reliability.When i go to a hotel or so i use to carry just one watch but i do never left it in the room so i wear it all the time including in the spa, beach or anything. i use to wear a Sub and i feel the trip lock to be perfect, will a twin lock crown Rolex stand the same?? I know many will think it´s wrong to take such watches to beach or spa but i like to enjoy them any time, watches are for use them! So, will a twin lock crown resist a bath in the beach or spa temps??
