What defines a hunter case pocket watch?

A hunter case pocket watch is characterized by its covered face, which requires the user to open the cover in order to read the time. This design feature is distinct and practical, providing protection for the watch face while also allowing for elegant aesthetics. The cover typically swings open or is hinged to reveal the dial once the button or latch is activated, making it a traditional choice among pocket watches.

The other options do not define a hunter case pocket watch appropriately. While waterproofing, shock-resistance, and sporty designs can be features of some watches, they are not defining characteristics of a hunter case. Additionally, a digital display fundamentally alters the essence of what a pocket watch is, which traditionally features an analog mechanism.
