The 1827 exhibition was a triumph for the Mediaeval style. At the following exhibition, in 1834, the company Bavozet Frères et Sœurs showed a clock replicating the portal of Reims Cathedral. It was a success and the firm later announced that it sold clocks representing the cathedrals of Reims, Rouen and Nôtre Dame in Paris.
