I think the watch might be mine. There was quite a jumble of packs at the base of SML when we were there. I thought I gathered up all our gear when we moved on but have been missing the watch since then. I believe it is a relatively inexpensive timex with an Indiglow face, hour, minute, second hands, day and month windows, sort of grayish green in color with a metallic expansion band.
If that's what you have please email at email@example.com
so I may send you my address.
