Related to an Addendum to my article “Centenaire de Abraham Breguet: Mélange de bric et de broc” concerning Breguet Sympathique No. 430 I have been trying to locate pictures of two Sympathique clocks, namely Nos. 46 and 247 but the search has been in vain, rather an utter failure.
More-or-less there are a bakers-dozen A.L. Breguet-era Sympathique clocks (either lifetime or Neveu & Cie); pictures of 11 of the clocks are readily available but clocks 46 and 247 are Bigfoots. Both clocks set the time and regulate the watch.
Helmut Mann’s Sympathique article (Alte Uhren, July 1982) notes Sympathique clocks Nos. 46 and 247 reside in the Palais Royal Madrid and David Salomons Breguet (1747-1823) notes both clocks having been sold to the King of Spain.
Emailing museums in Spain in vain I was referred to the article: The measure of time: Kings’ clocks in the eighteenth-century Spanish court (Amelia Aranda Huete, Curator of clocks, Patrimonio Nacional, 2012). There are two mentions of “sympathetic” clocks.
Chapter IV CHARLES IV, the clockmaker king page 78
In addition to this crate the lady brought a smaller crate containing “the pendulum clock that sets the time of the watch” (la péndola que pone el Relox a la hora) which the queen had commissioned from the master clock and watchmaker Breguet. This clock was to be transported to Aranjuez as the queen required it urgently. So began the commercial dealings with Abraham-Louis Breguet, who enriched the royal collection with several timepieces, especially pocket watches. Breguet was notable for the technical perfection of his movements. One of his technical breakthroughs was the creation of sympathetic clocks like this one, which the Spanish queen must have commissioned from him. These clocks were used to wind and set the time of pocket watches. (see note 332, page 136)
Note 332: The Patrimonio Nacional collection preserves a sympathetic clock made by Breguet’s firm but dated 1850; it was made in the nineteenth century by the firm’s heirs.
