273°: Our flagship model with patented big date display and power reserve indicator

Our Zeitwinkel 273° model features a high degree of suitability for everyday use and a comfortable fit. The large patented date display at the 11 o' clock position is particularly noticeable. Two large windows assure that the date can be read even when the lighting conditions are less than optimal.

A power indicator of the remaining power completes the dial. Turn the Zeitwinkel 273° over and enjoy the view: the Zeitwinkel caliber ZW0103 manufacture movement is always worth a look due to its luxuriously decorated German silver plates.

An especially large small-second, which can be fabricated in this manner only using a movement that has been adapted especially to the size of the watch, also allows the measurement of shorter periods. The second hand also shows, even at just a glance, that your watch is running perfectly.

The length of the hands was coordinated precisely to the minute markers and the indexes that are located at intervals of five minutes. The seconds display confidently rests at the 6 o' clock position without distracting the owner of the Zeitwinkel 273° from reading the time.

The noteworthy feature of the Zeitwinkel 273° is found at the 11 o' clock position. A large, easily readable date display shows the day of the month made possible by our ZW0103 manufactory movement. It reliably moves to the next day at exactly midnight; the date display only needs to be corrected in months with fewer than 31 days.

To be able to install the large date display in this unusual yet functionally logical position, the date mechanism had to be completely redeveloped. We have been awarded a patent for this construction.

The Zeitwinkel 273° has a power reserve indicator located between the 1 o'clock and 2 o'clock positions. In normal use, the automatic winding mechanism in the caliber ZW0103 manufacture movement keeps the watch wound.

However, if you occasionally prefer to place your watch on a desk or even, against our express advice, wear other manufacturers’ watches, this display is very useful, as it shows how long your Zeitwinkel 273° will continue running reliably.

The dial

The dial of our Zeitwinkel 273° reflects the high value of this mechanical timepiece. In addition to the central display of the hours and minutes, we have milled out a so-called "small second" in a finely structured area at the 6 o' clock position. In addition, we have integrated a date window at the 11 o' clock position that gives this model its distinctive appearance. Of course, the numerals used in the date display are our own Zeitwinkel font.

A power reserve indicator completes the dial, set at the 2 o' clock position, using a high-quality scale with metal application in an area that has been milled out especially for this purpose.


Our Zeitwinkel model 273° is available with a choice of a dial in Black, Galvanic-Blue, or Silver as well as our Zeitwinkel 273° Saphir fumé model with transparent dial.
