ZRC Grands Fonds Spirit 1964 Owner Review : Addictive, endearing and historical

Exact reference for those in the know: ZRC 1904 1964 Spirit GF41218. I find this "new" version of the Spirit more accomplished, recovering the logo with its inverted triangle, gaining a needle with a red finish at the tip, a particularly reflective ceramic bezel. I did not make the (deliberate) choice of steel on the bracelet although the versions dedicated to the 40-41mm models are from my point of view qualitative than the recent steel bracelets dedicated to the so-called "38" models (actually 39mm in diameter). This one is given for 41.5 but my caliper remains on 40.7 approximately... a matter of mm more or less... No matter, heavy case with its anti-magnetic back comfort on the wrist. This model exists with and without date. Aesthetically, the window being quite small and not overlooked by a bubble on the Sapphire, it is discreet. Spirit obliges, these colors are subtly patinated just like the falsely white indexes, the lume is always effective after exposure. Like all ZRCs with the crown at 6 o'clock I find the winding tedious with always the fear of slightly twisting the stem. So you have to be a little careful. Nothing bad. Delivered for my part with a "2-part Nato" with scratches, I preferred a Kundu leather coming from a craftsman that collectors like me appreciate (Xamlam to pay tribute to him) which reinforces this vintage, dated side. Naturally to be avoided for diving. I find this model a real success, meeting precise specifications, a dial ultimately more lively than its elder, materials reflecting light, a real presence on the wrist (a little heavy even on steel). My only regret, a movement with 38-40 hours of reserve which is not in-house (at least it is reliable and easy to repair in case). We would like (I would like) a movement with a more substantial autonomy (60-72 hours for example). This watch remains very endearing, with a history and a large community that give it an extra soul!
