The Andretti is of course named after the great racing driver Mario Andretti who is still very much still alive and kicking! There are many images of Andretti wearing his 3646, it looks like his had the Hour bezel, but it's difficult to be 100%. Ours here has the Minute bezel, which, being less busy than the tachy bezel is perhaps easier on the eye and this one is in terrific condition. The dial of this piece is also in wonderful condition with lovely clear subsidiary dials and all the lume on the dial and the hands is original. Probably the best part about this piece though is the case, which has never been polished, and the all-important bevels on its lovely slender lugs are razor sharp. As commented on by Richard Crosthwaite and Paul Gavin, the 3646 shares many details with the 2446 but it's driven by the Valjoux 92 movement which was designed for a watch with 2 subs, as opposed to the 2446 which had the Valjoux 72 designed for dials with three subs. Continuing the similarity with the 2446, the 3646 has the early-form screw-back with the Heuer monogram engraved on the back cover. The 3rd. execution came with all four variations of bezel – Minutes, Hours, 12-24 & Tachy.
