New from A. Lange & Söhne – Zeitwerk Minute Repeater

Here’s something brand new from A. Lange & Söhne! It’s the Zeitwerk Minute Repeater, their second model in the Zeitwerk family, and in fact, their first watch to feature a striking mechanism sounding the hours, ten-minute intervals, as well as minutes. And each one of these has a different tone: the hours are indicated by a low-pitched tone, while the ten-minute intervals are indicated by a double tone. Finally, a high-pitched tone indicates the minutes. The striking mechanism is activated by an elaborate pusher system, instead of using conventional slide.

Instead of conventional hands, the hours and minutes are indicated by jumping numerals

One of the most interesting things about this watch is how the hours and minutes are displayed, using jumping numerals. You’ll easily notice them and 9 and 3 o’clock, underneath which are the hour ring and the minute discs, respectively. These two apertures are framed by a time bridge, which is made of black-rhodium German silver. Next, we have a separate sub-dial for seconds, located at 6 o’clock. Surrounding this component are the two gongs, the one on the left for hours and the other for minutes. The ten-minute intervals are indicated by hammers striking both gongs slightly offset in time.

The dial itself is made of solid silver, which has a nice rhodium hue. On the upper portion, we’ll notice the power reserve indicator, which shows how much of the 36-hour power reserve is left. The indicator also features a red mark, which tells us when the power reserve has reached 12 hours, which is the point where the striking mechanism can no longer be activated. Another safety feature is that when the striking mechanism is active, the crown cannot be pulled, thus preventing any potential mechanical conflicts.

Caliber L043.5

All this neat engineering is housed in a platinum case measuring 44.2 mm in diameter, while the thickness is 14.1 mm. At 2 o’clock, you’ll find a matching crown, while at 10 o’clock we have a pusher for the striking mechanism. Completing the case is a sturdy sapphire crystal. As for the water resistance, the timepiece can withstand pressures of up to 3 bar.

The solid silver dial is complemented with a time bridge made of black-rhodiumed German silver

Inside this watch, we have the caliber L043.5, beating at 18,000 semi-oscillations per hour. It’s a highly complex movement, comprising a total of 771 components. One of the most interesting things about this caliber is certainly the striking mechanism – to ensure the optimal quality of the sound, engineers had to carefully calibrate the movement with the case, paying attention to the smallest details.  Other notable components here include the in-house manufactured balance spring, as well as a shock-resistant balance wheel, which has eccentric poising weights. Also, this movement features a precision beat adjustment system.

Last, but certainly not least, we have a stylish black alligator leather strap completing this new Zeitwerk. This is a hand-made strap, whose color creates a nice contrast with the platinum case, and also the complex dial. The strap itself is completed with a deployant buckle, which is made of platinum, just like the case.
