I claim the ornamental design for a golf accessory belt buckle, as shown and described.
FIG. 1 is an exploded perspective view of a golf accessory belt buckle, showing my new design;
FIG. 2 is a perspective view thereof;
FIG. 3 is an exploded front elevational view of FIG. 1;
FIG. 4 is an exploded rear elevational view of FIG. 1;
FIG. 5 is an exploded left-side elevational view of FIG. 1;
FIG. 6 is an exploded right-side elevational view of FIG. 1;
FIG. 7 is an exploded top plan view of FIG. 1; and,
FIG. 8 is an exploded bottom plan view of FIG. 1.
The broken line boundaries in FIG. 7 define portions of the golf accessory belt buckle that are not claimed. The broken lines and surfaces they enclose form no part of the claimed design.
