Limited to 500 pieces, this navigation chronograph with its beautiful light blue sunburst dial is the perfect introduction to a completely redesigned series. As a whole, it operates at what could be considered a unique technical level.

At the same time, the functionally designed dial with its fascinating performance characteristics imprints the navigation chronographs in our product range with decades of tradition. For example, the slide rule bezel with its logarithmic scale can be used to calculate times, distances or fuel consumption. Of particular note: We use hybrid ceramic luminous elements in the indices, which are meticulously attached by hand, the number 12 and the hour and minute hands. By integrating the illuminating pigments into the respective hybrid ceramic moulded part, we achieve a high concentration of the illuminant. The result is extreme brightness and perfect readability in the dark.

Above all, however, the redesign of the case once again demonstrates our company’s high level of innovation. This case features a silver-electroplated bezel on the inside which can be smoothly operated from the outer diameter of the watch. The watch’s impressive waterproofness of 20 bar in this construction testifies to a feat of engineering that has long distinguished the SINN brand.

The design of a classic navigation chronograph is perfected by the Tri-Compax arrangement of the silver-electroplated counters. The technical highlight of the 903 St HB model is its column wheel chronograph movement, which has a power reserve of at least 60 hours when fully wound. The attachment of the SINN logo as an appliqué is another aesthetically pleasing detail of a consistently sophisticated watch.

In addition to the fascinating variety of features, Model 903 has long been renowned for its meticulously designed dial. Watch connoisseurs appreciate the fine details as well as the impressive clarity in the how the functions are arranged.

An eye-catching feature of the 903 is the additional crown at 10 o'clock. This is used to rotate the slide-rule ring around the outer edge of the dial. With this high-quality navigation chronograph, you can perform multiplication and division, calculate proportions and do various conversions.

The dial of this timepiece series is one of the most difficult to produce, with over 30 separate steps involved. To ensure that it retains its rich contrast and colorfastness, it is galvanized with black nickel coating. The counters are then milled into the dial using diamond planes and galvanized with silver nickel coating.

Thanks to the proven high grade automatic movement, the 903 remains both durable and reliable. We have arranged the minute and second counters as well as the small second second counter at 3, 6 and 9 o'clock. The date display is located at 4:30.

For many watch lovers, a hand-wound movement represents the purest form of a mechanical watch: no rotors hide the movement, and the regular winding becomes a beloved ritual. Thus we are extremely pleased to present to you with the 903 Classic and 903 H4 two navigation chronographs with the rare Lemania 1883 hand-wound movement. Together with their perfect readability, clear arrangement of functions and ease of use, they also possess characteristics that users of a watch with a slide rule function need to carry out mathematical calculations. Moreover, with the use of such an instrument comes the good feeling of practicing an art of technical calculation that few people have mastered these days. Both models are practical instruments with which practically anything can be calculated - and which permit their wearers to show off their expertise and style. While they are identical with regard to suitability for everyday use, durability and state-of-the-art technological features, they differ in appearance due to the various colors of the minute and hour counters, the little second counter and the bezel. The value of these watches is enhanced by the fact that the Lemania 1883 hand-wound movement is no longer made. This may intensify the desire to possess these watches - not only among watch collectors.

For many watch lovers, the use of a hand-wound movement represents the purest form of a mechanical watch. No rotor impedes the view of the movement. Regularly winding becomes a personal ritual. For those who are fascinated by a traditional hand-wound movement, there is a special series of our classic 903 navigation chronograph. This navigation chronograph has everything you need for precise orientation in time and space. The minute counter and the small second counter are at 3 and 9 o'clock respectively, while the hour counter is positioned at 6 o'clock. The second stopwatch hand at the center of the timepiece has a red triangular tip. The design of the classic Lemania movement permits the integration of an additional complication in the Sinn 903 H4: the moon phase display is positioned in the circular field for the hand date at 12 o'clock. Thus a fourth time display completes the selection on the inner surface of the dial, making this model the most complex version of our navigation chronograph.
