... Tournament, I believe. Based on information I saw on eBay, I think this tournament was held in two years (perhaps 1975 & 1976, the year Hughes died).

Awhile back, I bid on a plate from one of the two tournaments (didn't win it). Here is a watch from the 1976 tournament (with picture below):

The logo is slightly different than yours, so I think your item is from the other year in which the tournament was held.

It is the lower left logo that is different -- on the watch it is clearly DI. ----- jim o\-S
