1970s Wittnauer Dual-Time Gold-Plated (Ref. 5025) 'Cal. 5K'

Founded in 1885 by Swiss immigrant Albert Wittnauer in New York, Wittnauer established itself as a brand dedicated to precision timekeeping for exploration, aviation, and navigation. Though often overlooked today, the company played a meaningful role throughout 20th-century horology, even accompanying astronaut Neil Armstrong during the Gemini 8 mission. The brand consistently balanced technical ingenuity with distinctly period-driven design, and few watches capture that spirit better than this remarkable dual-time wristwatch from the 1970s.

Presented in a striking gold-plated integrated bracelet case, this piece embodies the bold futurism of the era through its sculptural form and richly textured finish. Its defining feature is the elegant dual-time display, powered by opposing Cal. 5K manual-wind movements and operated independently via slim crowns positioned at both 3 and 9 o’clock. The contrasting champagne and deep purple sub-dials, each adorned with stylized Breguet numerals, create a playful yet sophisticated visual balance rarely seen in vintage watch design. Equal parts functional travel watch and avant-garde statement piece, this Wittnauer stands as a wonderfully eccentric example of 1970s creativity.
