I cannot find a public link, but I recommend any WatchTime subscribers check out this article in this issue. (October 2016). It is a fantastic article. I could not help thinking that it would have been even better if they had employed the research and writing skills of our own Dean, Joseph, and Alex, however.
LOL, slip of the fingers I'm sure but Fwench reminded me of some accents heard around London. The WT article doesn't appear to be available online yet but the story of these A-L Breguet and J-P Marat is an exciting one that is inconceivable today. Sadly, couldn't find any images on the web showing Marat "dressed-up" .
I wonder how much the author relied on the 1952 article by Alfred Chapuis published in the Journal suisse d'horlogerie. Chapuis was a busy fellow back then, it was also the year he co-wrote a most useful reference; Technique and History of the Swiss Watch.
Surely it is user error. If you hit reply, you will see all the pages - in low quality admittedly.
"Say "Roger"!" (LOL)
Here is the link...
Because so much watch-making in Pre-Revolutionary France was to royals, the watchmakers had to dissassociate themselves from royalty during the Terrors. Leroy (le-rah) went so far as to sell his company to an assistant for a franc until things blew over; then re-purchashed it and started making watches for Napoleon and the military, as did Breguet. A wondefully fun book on Breguet is Marie Antoinette's Watch: Adultery, Larceny, & Perpetual Motion by John Biggs, published in 2015.
