My
article entitled, The Novel Technology of
Sigismund Rentzsch, was published in the September 2017 issue of Clocks Magazine. Rentzsch’s contemporary, Joseph Anthony
Berrollas, was the subject of my article published in Volume 38, Number 2, (June
2017), of Antiquarian Horology,
journal of the Antiquarian Horological Society.
I referred to these two distinctive watchmakers in the post here of 8
June 2017.
Both
have been featured in enquiries I’ve subsequently received, confirming the especially
interesting nature of their lives and work.
Regarding
JAB, a horology enthusiast kindly sent me details of Berrollas timepieces he
has owned, most particularly a drum alarm, #1500:
Having
also owned a Berrollas carriage clock, my correspondent was able to reflect on the
maker’s apparently peripatetic lifestyle between England and the
Continent. He comments: ‘His English
work has French characteristics, and the French clocks have English details. On
his English clocks I have only seen going barrels, not fusees. On the French
clock escapements there are English details, like the recessed index, jewelling
& hairspring stud, as on my carriage clock, (on the main spring of which is
the date 1842).
He
adds: ‘About 30 years ago I looked at a similar clock to #1500, in The Museum of the History of Science in
Oxford. The Museum’s example is
signed, James McCabe, and the curator had no wish to be told that Berrollas had
made it!’
I
would like to think that my article on Rentzsch would have been a further
contribution towards his profile, though this should have already been high
enough to support the notion that examples of his work merit above-average
valuation as they come to the market from time to time; certainly I would
expect to Rentzsch to be considered ‘collectable.’ So I’m somewhat surprised that it has been
possible to acquire a good-looking example in 2020 for less than £600.
Dating
from 1807, the open face pocket watch featured in a Bonham’s sale last month:
Reverting
to 2017, shortly before my Clocks
Magazine article was published, this Rentzsch alarm came up for sale at Auktionen
Dr. Crott, Frankfurt Airport:
Circa
1830, it was described in the catalogue:
An exquisite “Pendule de Bureau” with “Petite
Sonnerie” and alarm. Case: brass; Dial:
silvered; Movm.: circular brass full
plate movement, heavy gold screw chronometer balance, 2 x chain/fusee, 3
hammers/1 bell.
A
good deal of quality and plenty of horological interest/complication I’d
suggest in return for the modest €1,500 winning bid.
