There are two pocket watches in RO: Pocket Watch  (2717) which is an equipment, and there's Pocket Watch [Etc.] (7513).
When you use @alootid +pocket watch, it automatically loots the equipment instead of the misc. collector item.
For that reason, use @ii pocket watch to find the item ID for the pocket watch (Etc. version), which is 7513. Then, autoloot using its item ID, like so: @alootid +7513
