4:48What technical perspectives shaped the invention of the grandstripe?
6:06Speaking about serving with the 10 patents, I'm absolutely sure that shop manufacturer is not doing the patents just for the sake of the number of the patents but to serve a bigger goal. So what is it?
7:39Which technical or architectural or even microarchitectural compromises you should made to achieve that?
9:42As I'm aware there is for the moment one watch maker who can assemble the watch and apparently it takes 2 months to do so. Well, am I right?
10:44How did you achieve that and what it means for the future of the chiming watch for shopar?
Hi guys, today we will dive into one of the most ambitious projects on the scene of hot herology. We are talking about Chopa Lu Grandst Strike presented at Dubai Watch Week. We have the pleasure to speak with Carl Fritz Shille who will deep dive with us into the philosophy and engineering processes of this watch. We must say that what is the most emblematic to this achievement is that 11,000 hours were put into the development of this time piece with 686 components inside with almost three decades of pursuit that was started by Carl Frederick Sche vision to have this new standard of chiming watches for Shopar manufacturer and the last but not the least 10 patents that were created especially for this time piece. So my first question, thank you very much for being with us today.
What I would love to ask you is a tricky one. Can you explain the new Luc Grand Strike to someone who is just at the beginning of the love affair with the watch world?
Yeah, that's not an easy one because we're looking at one of the most complicated mechanisms, chiming mechanisms that we've made as a brand for sure, but it's probably also one of the most complex mechanisms you find in... As you said, when you're beginning in watches, getting interested in complications, I like to look at the function first. And the chiming watches have a very interesting history because they were used to tell time when there was no lights around at the time where you had candles. And so it was a pretty interesting way of making your watch tell you the time even when it was completely dark. So that's the first thing to keep in mind is we're reading time with sound. And on a grand strike, on a gren, you're reading time with sound at a whole different level because you have different modes that let you either have all the time being read, only a little bit of the time, or you put it on mute so you're not disturbing anyone in a meeting. So in a nutshell, it's a watch that tells the time with the sound with different functionalities.
On the grand strike you have the grenery which is the most complete way to tell the time. So hours quarters. Then you have the petitenary which will not give you the quarters. And you have the mute which will not make the watch chime at all. To change the modes we have this little nifty button here which you can press. It gives you a nice haptic feedback a bit like on a ball pen. So this was the inspiration. Exactly. Because you have this nice feeling when you press on a ball pen. It has a nice kind of analog feel. Very satisfying. And so you can change the mode with this. Right now we are on P which is we switch over to Gener and Sance or silence.
So 12 hours of power reserve in the grand strike mode which is the most energy thirsty setting of the watch because basically your watch is kind of always chiming. And it was funny we were showing it to a couple of collectors and it was in gren mode and it seemed like the watch just always kept chiming. So having that much power reserve when you're in a mode such as is important because you want to be able to hear your watch. So 12 hours is a pretty comfortable power reserve for such a watch. So the power reserve is not necessarily a patent that we focused on. But that's due mostly to the fact that we have two barrels. one to store the energy for the chiming mechanism and one that is for keeping time basically. And the fact that you have two barrels allows you to store energy over and deliver it over a longer time and you do so by turning it one way to fill up the barrel for the time and the other way for the chiming mechanism. What we didn't mention about the three modes that you can set on,
you have this very nifty little selector right here with which you can set the different modes of the watch. And basically the effect is a bit like a ball pen
