  • Full Spec

    The Case 
    Classic Autavia Tonneau Case a large chronograph at 42mm in diameter (excluding crown & pushers) 47mm lug tip to lug tip with 20mm lug spacing. Usual calibre 12 "Lefty" configuration with the chronograph pushers located 2 & 4 o'clock position and the crown at 9. Original Faceted crowns correct HEUER signed crown. 
    Case is in ALL ORIGINAL condition unpolished with nice sharp edges and complete brushed steel radial finish to case front 
    This is the 1163V Piquarez case so the slimmest of and most refined 1163 cases available. 
    The Bezel 
    Cosmetically one of the few differences between the 1163 MH Autavia and the Viceroy lacking the wording "Tachymetre" from the 1- 3 position on the bezel instead of a more complete numerical marking with 5 min (or 1-60) numeric markings and dot markers at a 1-1 scale. 
    A 60 click bi-directional bezel with good sharp resistance and an affirmative "Click"
    The Dial
    This is super classic Autavia 1163 dial classic reverse panda "Static" dial, that's to say there is no running movement in the dial without the Chrono running so continuous seconds, 
    A 12h counter at 9, 30min at 3 Hours and minutes are those funky "Stick" hands and red centre sweep chronograph.
    Date aperture at 3. 
    The Band 
    Simple genuine leather vintage perforated rally type strap inkeeping with the watches age and style. 
    The Movement 
    The Caliber 12
    Arguably one the first automatic chronograph movements 
    For a VERY comprehensive understanding of the Caliber 12 and the arms race to produce the first automatic chronograph  search "onthedash Project99"Ii would give you the link but the eBay will not let you see it =(
