¡Bienvenidos al Foro El Cronometrista y gracias por su aporte!
Aquí hay algunas declaraciones que quizás desee aclarar;
"La mayoría de los relojes de repetición de calidad se fabrican en el mismo ebauche, pero con modificaciones específicas solicitadas por la marca"
En el período de 1850 a 1930, había más de una docena de empresas que fabricaban diferentes ebauches repetidos. La calidad del acabado fue determinada por los finalistas. Se sabe que a veces son muy diferentes.
“La evolución y desarrollo de estos mecanismos, principalmente en el mecanismo de repetición, ha sido el mismo en todas las marcas, desde 1850 hasta 1900”.
Algunos, incluyéndome a mí, podrían discutir esta afirmación. El período comprendido entre la década de 1850 y la de 1880 fue muy diferente al de la de 1880 a la de 1900.
“La evolución más importante fue una modificación simple pero muy importante, el diminuto corrector de piñón se levanta cuando termina la operación de repetición, se levanta para no interferir con el desempeño y precisión del movimiento. Por eso podemos ver y sentir en los relojes de repetición de calidad más antiguos un salto en cada trimestre a 15, 30, 45, 60 al momento de fijar la hora, esto se debe al salto de la llamada sorpresa del piñón minutero ”.
La pieza sorpresa fue una invención relativamente temprana, alrededor de 1840. La invención de lo que usted llama "corrector" (isolateur en francés) fue una mejora, pero mucho menos importante que los gobernadores silenciosos.
"Hablando de repeticiones, puedo decir que el único reloj repetidor con partes intercambiables es Longines"
¿Qué pasa con La Phare o Invicta, por ejemplo, quienes anunciaron que sus partes repetidas eran intercambiables?

Gracias por su bienvenida Sr. Poniz
Aclararé y me gustaría comentar varios conceptos, posiblemente no me he expresado bien.
Diferencio entre relojes de calidad y relojes comerciales, I stayed 1900 porque ya había producción en serie desde principios del siglo XX. Desde 1850 hasta 1900 no hubo tantos fabricantes de relojes de repetición de CALIDAD, no eran relojes accesibles para todo el
Welcome to the Forum El Cronometrista and thank you for your input!
Here are certain statements you may want to clarify;
“most quality repeating watches are made on the same ebauche, but with specific modifications requested by the brand”
Within the period from 1850 to 1930, there were over a dozen companies making different repeating ebauches. The quality of the finish was determined by the finishers. They are known to be sometimes very different.
“The evolution and development of these mechanisms, mainly in the repetition mechanism, has been the same in all brands, from 1850 to 1900.”
Some, including myself, might argue with this statement. The period from the 1850s to the 1880s was very different than from the 1880s to the 1900s.
“The most important evolution was a simple but very important modification, the minute pinion corector is lifted when finished the repetition operates, it is raised so as not to interfere with the performance and precision of the movement. For this reason we can see and feel in the older quality repeating watches a jump in every quarter to 15, 30, 45, 60 when setting the time, this is due to the jump of the so-called surprise of the minute pinion.”
The surprise piece was a relatively early invention, circa 1840. The invention of, what you call, “corrector” (isolateur in French), was an improvement but far less important than the silent governors.
“Speaking of repeats, I can say that the only repeater watch with interchangeable parts is Longines”
What about La Phare or Invicta, for instance, who both advertised that their repeating parts were interchangeable?
Thank you for your welcome Mr. Poniz
I will clarify and I would like to discuss various concepts, possibly I have not expressed myself well.
I differentiate between quality watches and commercial watches, and I stayed 1900 because there was already serial production since the beginning of the 20th century. From 1850 to 1900 there were not so many manufacturers of QUALITY repeating watches, they were not accessible watches for all the public because of the price.
I totally agree that these mechanisms evolved a lot from 1880 to 1900, as a result of the industrial revolution, but for me it focused on other aspects other than the repetition mechanism. Although it is true that the repetition was also improved and smoothed
The surprise piece is much older than 1840, we can see repeating watches from the 18th century with this piece, you can visit my website and see repeating watches from the 18th century with surprise,
www.elcronometrista.com
I differ from your opinion that the silent regulator was more important than the corrector or isolateur of free surprise, which did not interfere with the operation of the watch. I have seen numerous watches that the corrector or isolateur and the surprise were deteriorated, worn, and caused the watch to stop working, or that when touching these pieces the watch lost oscillation.
I cannot understand comparing LePhare or Invicta watches, with a nickel movement with 32,34,35,36 jewels. of the type, A LeCoultre, L Audemars, with escapement lever with compensation, bimetallic balance with gold screws, double jewel in the escapement, a first-class finish, etc. For me the LePhare and Invicta watches are not comparable to the watches we are talking about, in addition to being from a later time. For me LePhare and Invicta are second category watches, they cannot be compared although it is true that they are made in series and their parts were interchangeable.
Sorry for my English that is a bit rusty, I am at your disposal to continue talking about these fascinating issues
Soon I will publish a post on marine chronometers, of a very important watch, a Ferdinand Berthoud longitude chronometer from 1775, which I am finishing restoring. It has NO fusse or mainspring, the escapement works every 2 seconds, the balance weighs 230 grams. I am sure it will make watch lovers enjoy, and I would like to talk about this magnificent watch
Best regards
