Eberhard & Co Contograf Black dial Steel Chronograph Ref 31501Eberhard and Co is a brand that has always been very popular with Italian collectors and now the entire watch collecting community is taking note. This is a very nice sports chronograph with tachymeter scale on the dial and rotating 12 hour elapsed time bezel , we believe the triangle at 12 o'clock has been refilled with enamel in the past. The steel case remains in excellent condition with a corrector button on the side for quick setting of the date.
