Notes

Made with a calibre similar to that of Guinand No. 3321, sold by Antiquorum in Hong Kong, on 18 June 1994, but nickel plated instead of engraved gilt brass, this chronometer was certainly completed by the time of his death, if not by his successors.Ernest Guinand, from Le Locle (Switzerland), who died in 1879, together with Auguste Grether from Ponts-de-Martel (1817-1879), was specialised in the production of tourbillon carriages. His production of tourbillon began in 1865/67, they were controlled in Neuchâtel.He produced three models of Tourbillon carriages. He worked for several important makers including Girard-Perregaux and Montandon. It seems that No. 1060, sold to Girard-Perregaux, was the first, but does not carry his signature. From the study of the Observatory of Neuchatel records, the number of tourbillons supplied to Girard-Perregaux can be esteemed between 22 and 25. Most of his carriages were not signed and can only be identified by their shape.
