I have a doubt. How did they use the resolution of the wrist watch as the uncertainty. It could be 4s itself, or it could be 4.

Here, everything is constrained by 1s because of the least count or the resolution. So, the only thing safe to say about the measurement is to use that least count 1s as the uncertainty.

Least Count of an instrument is the smallest change or value of a physical parameter an instrument can measure or detect. For example, the ruler shown below can not measure a dimension more than 1 mm in length. Therefore ruler L. Least Count is inversely proportional to the precision of measurement equipment.

The smaller the minimum value an instrument can measure, the lower will be the L. Since Digital Vernier L. Therefore Digital Vernier is more precise compared to mechanical vernier because it has a smaller Least-Count. Least Count of an instrument is the smallest value instrument can measure.
