A. Lange & Söhne Zeitwerk Decimal Strike is another marvel from the Saxon watchmaker which is supplied with a complex striking mechanism. As it name suggests, it marks the passing of each ten minute interval with a strike of a gong. Naturally it also does it when each hour ends, while the only difference is a deeper tone that marks the longer interval. The novel piece features jumping hours and minutes displays. It is crafted from precious metals and it shows off the finest level of high-end decorations. Moreover, A. Lange & Söhne Zeitwerk Decimal Strike works on a proprietary hand-wound movement that features constant force mechanism. It is made in the limited edition of 100 pieces and it costs around $127,000.
Like the rest of the watches from the Zeitwerk collection, the newcomer is also modeled after the famous Semper Opera House clock in Dresden which chimes and has jumping indications. The latest tribute (the third one so far) to the famed clock in Germany is quite impressive.. Due to the frequency of its striking, the novel watch is somewhat different than it is common and as it is known this fact makes it more unique and therefore desirable. Furthermore, the complication is pretty useful since it allows one to know the current time without having to constantly look at the dial. It is easy to distinguish among the tones for the ten-minutes and hours, since the former ones are higher pitched.
For this, the timepiece uses two hammers that strike the gongs. They are both visible at the dial side (the one for the hours is on the left side). The gongs are placed on the lower part of the dial and they are embellished with a tremblant engraved pattern. These hammers lie on both sides of the small seconds counter which is placed on the very bottom. By the way, the dial is made of solid silver. Its top is reserved for the power reserve scale and in the central part there are also the mentioned jumping hours and minutes displays and their respective apertures. This type of display is in a way a bridge between a digital and an analog type of indication of time. Undoubtedly, it always makes the watch look very charming, while the indication is likewise very readable. Of course, it also shows the technical know-how of A. Lange & Sohne which has never been in question.
One of the traits that show the brand’s expertise as well is the manner in which it resolved the issue of demanding energy consumption for its two complications, jumping display of time and the striking mechanism. Each of these require a lot of energy. Unlike in most cases, where this is resolved with additional power source for the striking mechanism, this time all of the features are powered with a mainspring barrel. That is why the movement required a constant force mechanism, (or remotoire d’egalite) which allows its in-house movement to operate correctly.
The movement in question is manufacture Caliber L043.7 which incorporates as much as 528 components, of which 78 are jewels. It includes a lever escapement and it has a built-in shock-resistance system to guard its regulating organ that beats at the slow pace of 18,000 vph. The manually-wound movement has a power storage that lasts for 36 hours. Furthermore, it displays several haute horlogerie finishes. Among them is the Glashutte stripping for its three-quarter base-plate made of untreated silver from Germany. There are also gold chatons and a balance-cock with hand engraved embellishments.
A. Lange & Söhne Zeitwerk Decimal Strike also has a pretty lavish case which is made of honey gold, a proprietary red gold alloy that was developed especially for the brand. The same material is also used for the details on the dial, including the hands. The case of the newcomer is round and has the diameter of 44.2 mm and the thickness of 13.1 mm. Fortunately, it features sapphire crystals on both of its sides which allows better view on its extraordinarily beautiful movement. The watch is paired with a brown alligator strap which fastens with a clasp made of honey gold.
