Head into the map Customs. The Machinery key is required to access the Bronze pocket watch. So if you do not have one, head to room 205 located on the second floor of the three-story dorms building in the south.

To enter the room you'll need to jump on top of debris blocking the hall and crouch to get inside the doorway of the room. The Machinery key can be found within the blue jackets beside the wardrobe.

After obtaining the key, head north to the fuel tanker truck that is located at the construction site. The driver side door of the cabin can be unlocked with the Machinery key.

Inside, the Bronze pocket watch can be found laying on the floor in front of the seat. Be careful of the sniper Scav overlooking the truck from the roof of the nearby boiler building.

After picking up the pocket watch, it will be placed in your quest items inventory. You must successfully extract with the pocket watch to hand it in. If you die before extraction, you will have to retrieve it again. Hand the pocket watch over to Prapor to complete the quest.
