El Padre introduces the Bernhard Lederer Central Impulse Chronometer (CIC), a horological innovation building on the work of Breguet and George Daniels. This article delves into El Padre's firsthand experience and the technical discussion surrounding the CIC's unique escapement design, which promises unwavering accuracy under various conditions. The community explores the implications of its dual escapement wheels, individual barrels, and remontoir mechanisms.
I think most of us have heard of one of the geniuses of watchmaking - Bernhard Lederer. The guy who is behind many innovations presented by the world's best manufacturers, as well as the latest CIC - presented under his own brand - LEDERER.
The Central Impulse Chronometer is a system that is an evolution of Breguet's and George Daniels's approaches. The CIC features two escape wheels situated at the terminus of distinct gear trains, each equipped with its own barrel. Lederer has ingeniously redesigned the escapement functionality and architecture to ensure optimal impulses to the oscillator. Moreover, each set of escape wheels incorporates its own remontoir, a mechanism that replenishes a small spring every 10 seconds, ensuring a consistent flow of power to the escapement.
In comparison to conventional escapements, what distinguishes the CIC solution is its unwavering accuracy. While many classic designs may be precise under specific conditions, their accuracy tends to fluctuate with spring tension, watch position, or daily impacts. The CIC timepiece remains consistently accurate regardless of these variables, offering stability in precision under all circumstances.
What are your thoughts on this innovative concept and the watch itself? Do we have any proud owners of Lederer watches among us?



...are there any numbers? From an independent source I mean.

However, there's now at least one which is said to be running well. Hopefully, all issues have been resolved. These kind of things are very common in high-end watchmaking and usually not spoken about. I have a question about the design: The escapement requires very tight tolerances and the shock protection does not assure that these tolerances will not be exceeded in the event of a shock to the watch. So, I would advise owners to have some care in wearing (which they are likely to do in any case
I had the opportunity to shake this watch and it still worked perfectly. This is the whole clue of the concept. 🤔
No, a slight shake would not prove any sort of concept. I did not say the reason the first watches did not work was the problem with shock protection. The joy of a watch like this is its complexity. However, that is also more points of failure. I said that the shock protection is my question, given the differences between the fine tolerances needed for the escapement and the larger tolerances assured by the shock protection used. I have never received an answer, but I remain curious.
