The ornamental design for a knit watchcap with ammunition holder, as shown and described.
FIG. 1 is a perspective view of a knit watch cap with ammunition holder showing my new design as it would appear when being worn, wherein the cuff is curled downward in part to expose portions of the ammunition holder, for clarity of illustration;
FIG. 2 is a right side elevational view of the cap of FIG. 1;
FIG. 3 is a top plan view thereof;
FIG. 4 is a front elevational view thereof;
FIG. 5 is a rear elevational view thereof;
FIG. 6 is a left side elevational view thereof; and,
FIG. 7 is a perspective view comparable to FIG. 1 except with the cuff flipped up.
The broken lines in the drawings represent environmental subject matter that forms no part of the claimed design. The partial human figure shown in dashed lines in FIGS. 1 and 7 is included to assist in showing how the claimed design may appear when worn, and forms no part of the claimed design.
