“This is the genesis of the Heuer divers, the daddy. Heuer wanted to get into the skin diver / sports watch market, but didn’t want the expense of tooling up.. so in the late 70’s they outsourced the tooling to Monnin in France.. and they proved popular, so manufacture was eventually move to Switzerland & the rest is history.”
