ClassicHeuer offers some original spareparts for miscellaneous Heuer chronographs. Please understand that we will not sell all spareparts for Cal.11 and 12 available on stock. We will need the rare spareparts for the repair of delivered chronographs. You are welcome to give your timepiece in repair to our master watchmaker. ClassicHeuer attaches great importance to replace the individual parts only by original spareparts while repairing.
