The ornamental design for a watch, as shown and described.
FIG. 1 is a top front view of a watch according to my novel design;
FIG. 2 is a left top perspective view of a watch according to my novel
design; and,
FIG. 3 is a right top perspective view of a watch according to my novel
design.
The written indicia "Boxter", "Limited Edition", and "Swiss made", and the
watch band and buckle do not form any part of the claimed design. Also,
the particular date shown in the drawing figures, in this case, the number
eight (8), likewise do not form any part of the claimed design.
