The A. Lange Sohne Zeitwerk watch was certainly controversial when it first came out but has become one of the most iconic watches of the well-regarded German luxury watch brand. Since its release, A. Lange Sohne has perhaps come out with more truly interesting versions of the Zeitwerk than any other model save for perhaps the brands flagship Lange 1 collection. Today, we take a hands-on look at the most prestigious and complicated Zeitwerk to date the A. Lange Sohne Zeitwerk Minute Repeater.Those familiar with the history of A. Lange Sohne in Saxony in Glashutte being located near Dresden will understand that the basic inspiration behind the digital mechanical watch is a clock at the Dresden Opera house which also had a digital display for the hours and minutes. Few people know that, and for many people, the A. Lange Sohne Zeitwerk actually represents a wonderful melding of themes. One theme being that of the world of traditional timepieces, and the other theme being that of the digital era and our increasingly non-analog way of reading information. Whatever your take on the A. Lange Sohne Zeitwerk is, or what it represents to you, it is an undeniably and very much deserved success for A. Lange Sohne. In fact, the brand itself has been changing quite a bit over the last few years. From quiet, humble, hardcore watch makers and engineers up in the mountains, A. Lange Sohne is increasingly trying to market itself with participation in luxury events and opening brand boutiques in key cities around the world. This is often something that begins with positive intentions and a desire for growth. A. Lange Sohne, after all, is part of the larger Richemont Group of brands. However, when a company shifts their goals to pure marketability and revenue especially when that company is in the business of producing expensive items for enthusiasts the results over time are often those that do not sit well with the brands original fans.I am not saying that A. Lange Sohne is headed in a bad direction from an image perspective. I am, however, saying that if the brand isnt careful, that could happen. At least for now, the same high level of care and detailing goes into the production of their timepieces that continue, in my opinion, to have some of the best looking if not the absolute best looking movements around. I encourage A. Lange Sohne fans to be honest with the brand during their dealings and purchases and offer feedback on what they feel is and perhaps inst working. I am pretty sure that the brand will listen if offered these types of opinions from the right people.Anyhow, lets get back to the mega Zeitwerk that is the A. Lange Sohne Zeitwerk Minute Repeater. In a sense, the 2015 release of the A. Lange Sohne Zeitwerk Minute Repeater is odd because very recently, A. Lange Sohne released the Zeitwerk Striking. went hands on with the Zeitwerk Striking in 18k pink gold here. Honestly, to the uninitiated, the A. Lange Sohne Zeitwerk Striking and Zeitwerk Minute Repeater could look like the exact same watch at a glance. Each of them has a gong with hammers on the dial, and each adds chiming features to the overall package of complications. With that said, the two watches are very different not only in terms of complexity, but also price. Despite a similar looking dial, the Zeitwerk Striking has a movement with 528 parts while the A. Lange Sohne Zeitwerk Minute Repeater has a movement with 771 parts. In terms of prices, the Striking is almost $120,000 and the A. Lange Sohne Zeitwerk Minute Repeater is literally a few hundred thousand dollars more.Isnt that a lot of money for a minute repeater? Yes, I think it is. Even though A. Lange Sohnes own minute repeater offers some interesting features, this is certainly near the top of the minute repeater scale. That said, lets look at what makes the A. Lange Sohne Zeitwerk Minute Repeater watch special.A quick interlude, though, for those who dont understand the difference between a Striking watch and a Minute Repeater. The Zeitwerk Striking was a quarter striker, I believe. What that means is that when activated, the striking mechanism would use the gong and hammers to automatically sound out the time each 15 minutes. That means that the striking system was able to chime once for the hours, and then up to three more times for the quarter hour.Minute repeaters while similar in theory allow the user to activate the minute repeater system on demand, indicating the instant time. Minute repeaters indicate the time down to the minute, which makes them more sophisticated than quarter or even five minute strikers. What makes the minute repeater in the A. Lange Sohne Zeitwerk Minute Repeater unique is that it is a decimal minute repeater. Ok, so what is that?Traditionally, minute repeaters used chimes to indicate the current time in three parts. The first part is chimes meant to indicate the current hour. The next part is slightly different sounding chimes which indicate the quarter hour (15 minute segments). Finally, the remaining minutes are indicated via additional single chimes.In contrast to this traditional system, decimal minute repeaters altogether bypass the quarter hours and go from hours to 10-minute segments. This means the minute repeater chimes can take longer, but the result is something that most people consider being easier to read I mean, listen to. Decimal minute repeaters are rather rare, and the only other one that I can think of is the Seiko Credor Minute Repeater watch from Japan (which is amazing).A. Lange Sohne claims that the Zeitwerk Minute Repeater is the worlds first watch with a mechanical jumping numerals display and a decimal minute repeater. Who would argue with that? This is very cool, and at least good news for people who simply adore minute repeaters. I love the A. Lange Sohne Zeitwerk so much for how it blends what is so right with A. Lange Sohne and pure, unadulterated legibility. The A. Lange Sohne Zeitwerk Minute Repeater takes the concept into a more collector direction with its increased complexity and functionality, but it isnt something which is at all more useful on a daily basis.With that said, there are some other special features in the minute repeater complication that are worth noting. One of them is a pusher to activate the minute repeater versus a slider. The Seiko Credor Minute Repeater also did this, and it is becoming slightly more popular on other luxury European watches with minute repeaters. The benefit of a pusher versus a slider is that it reduces the potential to damage the movement which can exist if you dont fully engage the slider. A. Lange Sohne developed a few other security systems for the A. Lange Sohne Zeitwerk Minute Repeater such a system that prevents the minute repeater from being activated if there is less than 12 hours of power remaining in the mainspring barrel. A small red dot is placed on the dial-mounted power reserve indicator to mark this crucial point.A. Lange Sohne further claims that the Zeitwerk case has been thoroughly tuned in order to maximize the harmonics and reverberations of the chiming mechanism. That should mean louder and clearer sounds from the minute repeater when it is activated. With that said, what is odd is that A. Lange Sohne decided to put the Zeitwerk Minute Repeater in a platinum case (which is 44.2mm wide). Dense and very heavy, platinum (while very precious) acts to absorb sounds. Unless I am mistaken, my presumption is that platinum might be one of the worst materials to use for a minute repeater even though it isnt that uncommon.Remember, when producing minute repeater watches, brands are nevertheless producing luxury products for the elite. There is a certain expectation of wealth from these products and not many would take F.P. Journes position with the Sonnerie Souveraine and simply make their high-end minute repeater watches in a steel case.Inside the A. Lange Sohne Zeitwerk Minute Repeater watch is the amazingly beautiful in-house made caliber L043.5 manually wound movement. The Zeitwerks double jumping digital displays as the constant force mechanism to ensure that the accuracy is relatively consistent draw a lot of power as it is. With the addition of the minute repeater complication, the movement does what it can to keep up. A. Lange Sohne uses a rather steady frequency of 18,000 bph (2.5Hz) which uses less power than a 3 or 4Hz movement, but given all the power draw, the power reserve maximum is only 36 hours (even less than Zeitwerk Striking).Power has always been the weakness of the Zeitwerk, which must really be wound each day. Good thing it has a handy power reserve indicator on the dial. You can view the L043.5 movement through the rear of the watch, and it is amazing. You cant help but love all that hand polishing as well as the decorative engravings. This is really one of A. Lange Sohnes more innovatively complicated movements and it is a testament to their dedication that the A. Lange Sohne Zeitwerk Minute Repeater even works.Germanic and quirky, the A. Lange Sohne Zeitwerk Minute Repeater has all the stuff of a Lange collectors dreams. It is beautiful and a lot of bragging rights come with it. I do, however, hope that in addition to spectacle pieces such as this, we see more of the everyday useful ultra luxury watches from A. Lange Sohne that we all love. For my money, Id like to see an updated standard Zeitwerk with more power reserve and possibly one or two extra complications on the dial. A. Lange Sohne is not restricting the Zeitwerk Minute Repeater to being part of a limited edition, but it will naturally enjoy a very limited production annually. The A. Lange Sohne Zeitwerk Minute Repeater price is $467,700. lange-soehne.com [...]
