Pry up the black tabs, 2 top and 2 bottom, to release the face of the clock.
Find the 5 black devices on the circuit board. Here they are labeled 270, 510, and 3 at 181. These are what need to be resoldered.
Carefully remelt the solder at each end of each device. You probably don't need to add any solder, and you don't want to make any solder bridges where they shouldn't be.
