Morphology
watertightness = watertight (transparent) = water + tight + ness
The noun is a straightforward nominalization of the adjective 'watertight' with '-ness', and 'watertight' itself is a transparent compound of 'water' + 'tight'.
Etymology
Watertightness is made from water, tight, and the ending -ness. Tight means 'closed or secure' and -ness shows a state, so watertightness is the 'state of being tight against water' and explains how well something keeps water out.
