[João Neto]

Olá, ate que emfim, obrigado pela ajuda e a preocupação, eu tenho fotos em dois sites mas aqui nada deu certo ate agora; só com a chegada da GVT.
preciso da preciosa ajuda dos amigos, gostaria de saber se esse autor fez mais cronometros corda de 30hs estou pesqusando a 08 anos e ainda não, verdade que tenho pouco tempo.

Belo cronômetro!

Em caso tenho alguns livros sobre o assunto. Chegando lá, dou uma olhada pra ver se acho algo.

E a máquina, tem alguma fotinha dela para colocar para nós?

Um abraço,

Igor

Muito bonito. É um típico cronômetro inglês. Escapamento "spring detent", certo? Afinal, é um balanço tipo Earnshaw...

Chegando em casa será a primeira coisa que olharei, mas é muito provável que o tal "James Murray" não tenha fabricando inteiramente este cronômetro, pois esse design de movimento era o padrão da época. Deve ter sido subcontratado e finalizado por ele. Mas isso é um chute, claro...

Veja aqui um cronômetro assinado "Morris Tobias" com máquina muito similar à esta:

Salve!

João,
Ainda bem que você conseguiu postar as fotos! 

Amigo,
Eu já vi alguns cronômetros navais do James Murray e lembro até de já ter visto um relógio de bolso, todos em leilões, mas particularmente eu não tenho muitas referências ou informações sobre os seus movimentos, etc.

Vamos aguardar a busca do amigo Igor em seus livros, e esperar que algum outro colega, que possua algo a respeito, também se manifeste.

Um abraço!
Alberto

Murray Islands
'Murray Islands' is a group of small islands 1.2 nautical miles (2.2 km) southeast of Cape Whitson, off the south coast of Laurie Island in the South Orkney Islands. Discovered in 1823 by Matthew Brisbane, who explored the south coast of Laurie Island under the direction of James Weddell. The name "Murrys Islands" appears on Weddell's chart, but the islands are probably named for James Murray of London, maker of the chronometers used on Weddell's voyage.

Um abraço,

Igor

Onde a coluna a quer dizer "the difference between the greatest and least weekly sums" e a coluna b é "the greatest difference between the sums of two consecutive weeks". Lembrando que este teste era realizado por um ano!

Um abraço,

Salve!

Legal, amigo Igor!

Se me permite,...

O "oculista do Hubble" passou por aqui.

A única coisa nova que encontrei em meus livros é que o Mr. Murray aí teve um célebre funcionário: ninguém mais, ninguém menos que Edward John Dent!

Um abraço,

Mais informações, cedidas gentilmente pelo expert em relógios de bolso do fórum que está meio ocupado ultimamente:

Vejam que houve 3 gerações de cabras. Resta saber quem foi o responsável pelo relógio sob análise.


Murray, James of London and Calcutta ( India ).

There were four generations of makers all called James Murray.

James Murray (1)was born in 1780 in Church Street , Moffat , Scotland and later moved to Glasgow before coming to London in about 1810. He was freed from his apprenticeship in 1815 and was working in Cornhill from about 1814 until 1816. He became a liveryman of the Worship Company of Clockmakers in 1817 and established his business at 19 Sweetings Alley until 1818 when he moved back to Cornhill and took premises at number 30 where he appeared in trade directories for 1822/3, 1841, 1856.

James was a celebrated maker of chronometers and watches. Three of his chronometers were taken by Weddell to the South Pole between 1822-4. One was an 8 day model signed "Jas Murry", another was of 2 days duration signed "Murry & Strachan" and the third was of 24 hour duration and signed "Murry". All performed well and the report said:- "they all performed sufficiently well to recommend the makers for their very improved mechanism in this important art"

James was in partnership with Charles Strachan between 1814 and 1819 and then worked alone until 1846 when the business became Murray and Co. In 1823 James married. He died in 1847 and was succeeded by his sons – James(2) and John. Without more definite details for James and/or John it is impossible to locate them in census returns.

James Murray(2) was the son of James(1) and succeeded his father along with his brother John Murray. He is known to have been at 1 Royal Exchange between 1873 and 1875. In 1882 the business is listed at 1 Royal Exchange as James Murray and Co.

Around 1864 the business traded as Murray & Bros. for a couple of years before James worked alone again until the start of the 1870's. In about 1873 James went to Melbourne and worked from 107 Bourke Street East and then went on to Calcutta where he died in 1892.

James Murray(3) son of James (2) succeeded to his business in Calcutta . James(3) died in 1920 and was succeeded by James Murray(4)who was born in 1906 and ran the business from about 1930 until he sold up in 1947.

The business in London continued for some years, either as Murray and Co. or Murray and Mitchell. In the trade directories for 1891,1895, 1899 and also for 1902 they are listed at 1 Royal Exchange as chronometer makers and also as watch makers. Mitchell was a family relative from Glasgow.

Olá a todos, muito obrigado a todos pela atenção, estou feliz com as respostas. Agora  respondendo ao Sr. B. Recchia, ele foi me oferecido por uma familia muito querida em Lisbôa que são meus clientes e amigos, como agradecimento por salvar coleções, assim que aparecer tempo irei fotografar mais algumas peças para postar no forum.

um grande abraço a todos e muito obrigado, João Neto
