Heuer chronograph galvanic silver Ref. 347

The undisputed highlight of this Heuer chronograph is its remarkable black galvanic radium dial, distinguished by an exceptionally intricate arrangement of contrasting scales. The outer tachymeter, calibrated to a base of 1,000, is complemented by a kilometre telemeter scale, while two recessed subsidiary registers create the unmistakable symmetry of a traditional two-register chronograph. The fine printing, silver accents and original radium luminous details produce a striking visual depth, enhanced by decades of natural ageing. The warm patina of the luminous hands and hour markers contrasts beautifully with the dark dial, preserving the authentic character of an early professional timing instrument. Powering the watch is the celebrated hand-wound Valjoux 22, a traditional column-wheel chronograph caliber renowned for its robust construction and mechanical sophistication. Widely employed by prestigious Swiss manufacturers throughout the twentieth century, this movement represents one of the defining achievements of classical chronograph engineering. The movement bridge carries its individual serial number 70xxx, providing an additional historical identifying detail. Just serviced and carefully checked by our laboratory, this example is presented on a handcrafted Luxo Time Firenze oil-waxed leather strap in a rich brown tone, whose natural texture perfectly complements the aged radium and gilt details of the dial. A wonderfully evocative example of early Heuer chronograph production, combining historical aviation associations, sophisticated mechanical engineering and the unmistakable charm of an authentically aged black galvanic dial with silver graphics. A timepiece that captures the golden age of mechanical precision, when functionality and elegance were inseparable.
