A rare vintage Patek Philippe square Calatrava 3543 in still rarer original blue dial. Dial is 31mm but wears like a 34-35mm due to the large cushion case. Original 18K tang buckle, brand new suede strap. Running well as the time of writing. Signs of use all over, likely have been polished. The dial is original but has blemishes and imperfections particularly along the lower edge, but nothing too obvious at a glance. Will be shipped insured. Custom duty is buyers’ responsibility!
