The shop has been asked to handle creative work across all channels, including digital.
Havas Worldwide London has been given a specific remit for new brand advertising and responsibility for the Carl F Bucherer brand magazine. The campaigns will focus on Asia, Europe and North America.
Earlier this month, the brand created the Manero ChronoPerpetual watch in white gold for the Only Watch 2015 charity auction in Geneva. The sale of the watch raised nearly £30,000 for the Monaco Association Against Muscular Dystrophy.
Daniel Floyed, the managing partner at Havas Worldwide London, said: "Carl F Bucherer has a fantastic heritage. We are excited to be part of its first global campaign, which will help solidify its rightful position as a leading luxury brand."
Carl F Bucherer is a family-owned company that was founded in 1888. The brand, whose watches cost between £1,000 and £3,000, opened its first boutique, in Interlaken, Switzerland, last week.
