Zeitwinkel 273°: our watch with patented large date
Our model 273° is characterized by our patented large date display at the unusual position "11". The dial is rounded off by an off-center second hand and a power reserve indicator.
We manufacture the 273° model in a choice of dial colors and finishes. They are all powered by our manufacture caliber ZW0103 with 72 hours power reserve.
Already a classic
The Zeitwinkel model 273° is characterized by high suitability for everyday use and a comfortable fit. Particularly striking is the patented large date at position "11". Two large windows allow the date to be easily read here even in poor lighting conditions. The time display, power reserve and decentral second are harmoniously coordinated with the large date.
The back of the watch with our manufacture movement caliber ZW0103 is also worth a look thanks to its elaborately decorated German silver plates.
Our 273° is already a classic and certainly one of the defining models for Zeitwinkel.
Our model 273° with patented big date, off-center second and power reserve display is available with a case diameter of 42.5mm.
The date is of course displayed with numerals from our in-house Zeitwinkel typeface.
Dial and hands
For the dials of our model 273° we offer the colors silver, black and galvano-blue. We will be happy to discuss other finishes and special designs with you.
The hour and minute hands are exactly matched to the indices and the minute track. They are diamond-set, i.e. they have two straight surfaces that are set at an angle to each other over almost the entire length of the hand.
As a result, one side always reflects the incident light, thus creating a strong contrast with the dial.
For models with a silver dial, we designed the second hand in blue. Due to its coordinated length and color delimitation, it can always be read accurately.
The date display advances by one day at midnight, so it only needs to be corrected in months with less than 31 days. Manually, the date display is easily adjusted by means of a quick adjustment in the second crown position.
273° Bleu sur Argent
Blue hands, handmade
A very special variant of our model 273° is the version "Bleu sur Argent" ("BsA"). For these watches, we handcraft hour and minute hands, which we then blue over a flame.
Just like watchmakers did hundreds of years ago, we start with a carefully selected sheet of metal, which is cut and shaped. With a lot of patience, we then optimize the shape by hand, without using automated machinery or processes from mass production.
In the next step, our watchmakers polish the hands until they have exactly the right shape and surface finish. This can sometimes take a very long time, as the special steel we use is very hard.
The hands are then blued by hand over a flame until the desired shade is achieved.
Only when this step is completed do we see whether there are any inclusions or impurities in the steel. In this case, all previous work was in vain and we start over again with the first step.
Due to the amount of work involved, we can only make a few of these special watches each year. Please contact us if you are interested in our model 273° Bleu sur Argent.
The Zeitwinkel caliber ZW0103 is a mechanical manufacture movement with automatic winding and a semi-integrated complication for the date display. We developed it especially for our 273 series watches and manufacture it in small-quantity lots in the Swiss Jura with high precision machinery and meticulous horological diligence.
Based on our Zeitwinkel caliber ZW0102, we have added a self-developed complication for displaying the remaining running time and the date. We hold a patent for the special technical solution for the large date display at the 11 o' clock position. The running time of the movement is 72 hours.
The movement has the substantial diameter of 30.4 mm, 49 bearing jewels, a total of 387 components, a frequency of 28,800 oscillations, a Glucydur balance and a robust three-quarter plate that plays a significant role in the mechanical stability of the movement. All plates and bridges of the mechanism as well as of the semi-integrated complication are made of German silver, chamfered and hand-decorated.
The casing for our Zeitwinkel model 273° was developed in precise accordance with in-house caliber ZW0103.
It is constructed of 1.4435 steel alloy which has a high resistance to intercrystalline corrosion and non-oxidized acids, so it is particularly suited for products that are in continuous contact with skin.
To attain the characteristic shaping, each watch case is prefabricated using precision machinery. We then complete the construction primarily by hand. In this process, 26 parts are assembled in more than 80 individual steps.
The interplay of polished surfaces with strikingly structured, precisely worked areas provides every Zeitwinkel watch with its distinctive appearance. With a diameter of 42.5 mm, the casing has an elegant and well-proportioned appearance. It is water resistant up to a tested pressure of five bar.
We use sapphire glass on both the front and back sides of our timepieces. Sapphire is extremely hard and scratch-resistant and ideally suited for use in high-quality timepieces.
The convex lunette crystal has multiple anti-reflection coatings on the inside so that the hands do not reflect on the interior surface and because a coating on the outside of the crystal could wear down. The case large back glass is flat and equipped with an anti-reflection coating on the inside as well.
As a result, the time can always be easily read even under extreme lighting conditions. Both front crystal and back plate glass are tightly inserted into the casing of the watch, using an elaborate sealing system.
Due to its twelve grooves and its large diameter, the crown is very easy to grip when you set the functions of your watch. The surface is polished, but is kept matte surrounding the raised Zeitwinkel logo.
Screwed-down crowns are often difficult to handle, so we decided to use a multi-stage sealing system with dual O-rings. Even when the crown is raised, water cannot enter the valuable inner workings of your Zeitwinkel watch.
For our leather straps, only selected skins are processed and refined with with the traditional full-bugg technique. The result is a supple and extremely durable strap available in various colors. For animal welfare reasons, we completely abstain from using reptile leather and replace it by high-quality hand-sewn calfskin.
The exclusive use of vegetable colorants, antiallergic leather as well as caoutchouc-based glues provide for excellent skin friendliness and pleasant wear. Our Zeitwinkel folding clasp is made of antiallergic stainless steel 316L and can easily be opened and closed with one hand, while at the same time being as easily adjustable as a pin buckle.
Our watches with 42.5mm cases can optionally be ordered with our durable caoutchouc watch straps. Caoutchouc has proven to be very skin-friendly and extremely durable not only for the use in warmer climates, but also in sports. It is waterproof, UV-resistant, tearproof and dimensionally stable.
We have redesigned this antiallergic strap from scratch from synthetic caoutchouc free from harmful substances such that it does not bulge even when worn for a longer period of time. The Zeitwinkel logos which are embossed on the inner side of the strap provide for a better ventilation of the skin and improve wear comfort.
The Zeitwinkel caoutchouc watch strap is closed with a high precision manufactured folding clasp made of polished stainless steel 316L that can be opened and closed with one hand.
