Introducing: The Vacheron Constantin Les Cabinotiers Symphonia Grande Sonnerie 1860

A brisk recap on ringing watches: there are a wide range of varieties, however by and large they fall into only two classifications: the sonnerie, which tolls the time en passant, or “in passing” (that is, it will consequently ring the hour, and the hour and quarter hours) and the repeater, which rings the time on interest (at whatever point you press a slide or catch set into the case band). Grande Sonnerie wristwatches are extremely uncommon gratitude to their impressive complexity, and moderately couple of watchmakers and brands even endeavor them; the rundown of the individuals who have made, or right now produce, a grande sonnerie includes Gerald Genta, F.P. Journe, Audemars Piguet, Patek Philippe, Bulgari, Philippe Dufour, and Jaeger-LeCoultre.

The Symphonia Grande Sonnerie 1860 is intended to part with almost no of its complexity, in any event from the dial side.

In contrast to numerous grande sonnerie watches, the Symphonia Grande Sonnerie is practically grave in plan; there is almost no about the plan of the two-tone dial and 45mm white gold case that would hint you into the way that there’s a grande sonnerie inside. There’s no extraneous content on the dial, and at least signs: a running seconds, a force reserve for the primary timekeeping gear train, and a force reserve for the sonnerie. That’s it. 

grande sonnerie has two fountainhead barrels – one for the going train and one that controls the striking framework; the going train has a force reserve of 72 hours, and the barrel for the striking train gives sufficient capacity to 20 hours of striking (that is 20 strikes of great importance and 60 strikes of great importance and the current quarter hour). It’s not difficult to recognize the force reserve show for striking – it’s the one with the wave-molded hand. 

Both barrels can be wound utilizing the crown as well. Turning it clockwise breezes the essential origin barrel and turning it counterclockwise breezes the sonnerie barrel.

Strike mode for the sonnerie is set with a little switch on the bezel.

Pretty much the solitary sign that this is in excess of a basic watch, in any event on the off chance that you take a gander at it from the dial side, is a little switch on the bezel. This is utilized to choose the ringing capacity: GS represents grande sonnerie; PS represents petite sonnerie, or little strike, in which mode just the hours are struck; and SL, or quiet mode, during which no striking en passant occurs by any means (in little strike mode you will broaden your 20 hour power reserve, clearly). As is by and large the case with grande sonnerie wristwatches, the Symphonia Grande Sonnerie will likewise ring on interest as brief repeater (by squeezing the catch in the crown). 

Caliber 1860 has various highlights intended to improve unwavering quality of the striking framework, and decrease the danger of unplanned harm to the striking system.

The development is assigned type 1860; it was, Vacheron says, created and produced in-house. Measurements are 37mm x 9.1mm, with two barrels and it runs in 74 gems. There are a few specialized and wellbeing highlights of note in the development to note too.

One prominent component of the moment repeater strike is the end of the quiet interval that, in a standard repeater, happens between the finish of great importance strike and the start of the minutes strike, between the start of great importance and the primary quarter hour (for instance, there are no quarters to strike if the repeater is actuated at 12:14, so regularly there’s a concise hole where the quarter strike would be). In the Symphonia Grande Sonnerie this quiet interval doesn’t occur. 

While smooth and all around planned, this is certifiably not a little watch at 45mm x 15.1mm.

Vacheron additionally specifies that the development is furnished with a “non-hauling shock piece.” The unexpected piece is one of those complication-explicit parts a large portion of us never know about, however it’s essential in a repeater. The repeater component “peruses” the time from ventured cams (typically called snails) appended to the turns of the moment and hour hand. The state of these cams makes two issues. In the first place, it is feasible for a quarter hour to be struck unintentionally at 14 minutes past the hour, when there ought to be no quarter struck. It is likewise conceivable, at one to 59 seconds past each quarter, for 14 minutes to be ringed when no minutes ought to be struck (that is, at 12:15:30 you ought to hear just twelve hour strikes, and a solitary quarter strike, and no minutes).

The striking framework is normally covered up under the dial; moving it to the rear of the development allows you to see the complex arrangement of racks, cams, and switches in operation.

The two astonishment pieces “hop” into position when it comes time for them to do their thing. They in reality jump free from the moment cam and quarter hour cam: Surprise! (The name is befuddling – the unexpected piece is one of those couple of components named for its activity, not its capacity). Guaranteeing they work appropriately is one of the more troublesome acclimations to the development a watchmaker needs to make, and the energy to work them normally comes from the activity of a spring that flicks the unexpected piece into position. The expression “non-hauling” would appear to propose an elective framework is utilized in the Symphonia Grande Sonnerie – one that kills the grating normally connected with these springs, and which is enacted just when the repeater is really engaged. 

Actions by the client that may harm the instrument are obstructed by certain security highlights. Both the sonnerie and repeater are consequently withdrawn when you set the time; there is additionally a strike security highlight, which guarantees that in the event that you switch strike mode while a strike is occuring, the change to an alternate mode just happens after finish of the strike. The last significant security highlight is that the barrel for striking is withdrawn when force falls too low to even think about completing a full strike, either in passing or on demand.
