This Cartier Tank Francaise dual-time desk clock, reference 2945, is a portable timepiece consisting of two independent clock units joined by a central hinge. This construction allows the display of two distinct time zones simultaneously. The two units feature contrasting black and white dials, each marked with Roman numerals and the Cartier brand name. The white dial includes a date aperture at the three o'clock position. The hour and minute hands are finished in blue, and each dial incorporates a hidden Cartier signature within the VII numeral. Both units are housed in steel cases measuring 35 mm in length and 82.5 mm in width. The clocks are powered by quartz movements equipped with alarm functions, with controls positioned on the upper edge of the cases. The auction description reports the steel cases are in excellent condition.
