Battery life and waterproofing may diminish as the watch ages
or if it is repaired. This commit clarifies that the stated numbers for these
specifications can only be assumed to be true for new hardware.

+    <p><sup>*3</sup>Rated waterproofing is applicable to new, sealed hardware. Age or repairs may compromise water resistance.</p>
+    <p><sup>*4</sup>Rated battery life is applicable to new hardware in typical usage conditions. Heavy use or use of power intensive apps and watchfaces may lead to a lower battery life. Battery life will reduce as the watch ages. Aftermarket replacement batteries may have a lower capacity.</p>
