Tourbillon expert joins often the Grand Sonnerie Hall


After 11 years of analysis and development, tourbillon specialist GF is one of the few leading watch manufacturers capable of studying and developing Grande Sonnerie!


No matter which watchmaker anyone asks, whether it is difficult to make a awesome souvenir, you may get a look, an endearing smile or a frown, and the response should be clear enough. Naturally , the timekeeping mechanism will be difficult, especially the adulto sonnerie. Otherwise, if you look at this timepiece industry now, you can depend all the brands that can take action with two hands. Still this year is very special. VACHERON CONSTANTIN and GREUBEL FORSEY ) both released the actual brand’s first Grande Sonnerie and entered the hallway of watchmaking.

It’s just that Vacheron Constantin only launched the Grandissimo Sonnerie this year, which is a little surprising. After all, the development of the particular timekeeping mechanism has their origins. However , GREUBEL FORSEY, which started with a two times tourbillon, is not slow. The particular founders Robert and Sophie spent 11 years. It was a little while until time to develop this voluminoso sonnerie with 935 parts, two patents and 10 safety designs, proving it has the high-end technical strength as well as the tourbillon.

It has greater than 935 components, holds a couple of patents, has 11 built/in safety designs, and works with a titanium case to achieve far better resonance and is easy to use.

This grandissimo sonnerie uses a configuration regarding double hammers and increase gongs. I haven’t dealt with this watch personally, and that i haven’t had the opportunity to read it sound in person. I’ve merely watched the official video at the moment. In addition to the timekeeping device, FRIEND naturally also did not fail to include the signature 24-second tourbillon device. The case size can be maintained at 43mm and also 16. 13mm thickness, in fact it is made of titanium instead of us platinum that is commonly used in repeater watches. On the one hand, precious metals are brighter to wear, and on the other palm, they have better resonance.

Kinetic energy has long been a major problem in the development of keeping time mechanisms. Because the grande sonnerie needs to strike every quarter-hour, the demand for kinetic vitality is naturally higher. How can an individual barrel support it? GIRLFRIEND uses a rare device. Even though the watch is hand-wound, a great eccentric automatic disk is defined on the back of the watch to realise a 20-hour power reserve with an programmed winding system. This is GF's most complex device currently., limited to five to ten pieces produced each year.
