executing the master’s orders.
The OOW is responsible to the master for:

2. Safety of the personnel or crew onboard the ship

The Officer of the watch should keep his watch on the bridge until properly relieved.

These are among the duties of an Officer of the watch. I’d like to point out something more about this matter, which I mostly notice on the bridge.
The role of the Officer of the Watch when the Master takes command of the ship
Most of the time I’ve noticed that some OOW would simply stand on the radar, drink a cup of coffee, but forgot the most important part of his job. You are on the bridge to check if the captain is giving the right orders on engine speed, rudder command, following the instructions of the VTS, and applying the COLREGS.
You are there to check that everything is under control. This also applies when the ship is under
pilotage. Remember that the master has a lot of things running over his head. A lot of messages and emails to send, and to answer. And you are the person that he shall depend on the bridge to achieve the safe navigation of the ship.
