Tank 1648 - Lapis Lazuli Dial - 18k Yellow Gold - Watch Only - 1970s

DeLaneau Tank 1648 - Lapis Lazuli - Watch Only (1970s)

A refined DeLaneau Tank from the brand's early-1970s design chapter, this rectangular dress piece presents a natural lapis lazuli stone dial framed by DeLaneau's signature twisted-rope 18k yellow gold bezel. Founded in 1949 in Biel and long known for elegant jewellery watches, DeLaneau introduced its rope-twist godronné styling in 1973 and its lapis-dial dress pieces the following year - placing this reference squarely in that celebrated era.
