Running in some 120 countries worldwide, the "Keep Walking" campaign was further honoured with the Best International Multi-Market special prize.
It was credited with transforming the fortunes of Johnnie Walker, having helped deliver sales growth of 48% and incremental sales totalling around $2.21 billion (€1.73bn; £1.38bn).
BBH, which is part-backed by Publicis, won another Gold Award for its work for Kentucky Fried Chicken, a Silver for its creative output for Audi, and a Bronze for its marketing efforts for Cadbury's Biscuits.
Further Gold Awards went to the Home Office and RKCR/Y&R for their campaign focusing on stopping acquisition crime; Sainsbury's and AMV.BBDO for "Try Something New Today"; and UKTV and Red Bee Media for the rebranding of the digital television channel Dave.
