Heuer Chronograph

Partially verified

This Heuer chronograph is a hand-wound mechanical timepiece dating to the late 1970s. The watch features a grey fumé dial with contrasting white sub-dials at the 3 and 9 o'clock positions and a date window at the 6 o'clock position. The dial displays the Heuer logo, '17 RUBIS', and 'INCABLOC'. It is equipped with a Valjoux 7734 mechanical caliber, a movement known for its usage in Swiss chronographs of the era. The watch is presented in a stainless steel case described as unpolished. Features include steel stick hands with luminous material and a vibrant orange central chronograph seconds hand. It is currently fitted with a modern aftermarket leather racing-style strap featuring orange stitching. The auction description notes the dial condition as near mint and indicates that the case retains its original, unpolished finish with surface wear present.

Object description

Dial and Hands

The watch features a grey fumé dial with a gradient effect. Two white sub-dials are positioned at 3 and 9 o'clock, respectively, for the chronograph registers. The dial includes the Heuer signature, '17 RUBIS', and 'INCABLOC' text, with a date aperture located at 6 o'clock.

The timekeeping display consists of steel stick-style hour and minute hands filled with luminous material. A bright orange central seconds hand is used for the chronograph function, providing contrast against the grey dial. The dial is reported to be in a near-mint condition.

Case and Presentation

The stainless steel case is described as original and unpolished, exhibiting natural surface wear consistent with age. This includes visible signs of use on the bezel and case edges.
