Sinn is celebrating its 65th anniversary with a limited edition of one of its most peculiar watches. Not peculiar in terms of design, but because it feels like an outlier to the rest of their catalog, though in some respects, it’s also the most recognizable. The Sinn 903 is a pilot’s chronograph with an internal slide rule bezel that bears a striking resemblance to another famous watch, the Breitling Navitimer. But it’s important to note that it’s not a copy of a Navitimer. Rather, Sinn has owned the rights to this design since the late 1970s.
A cult classic, it stands out aesthetically from Sinn’s other instrument watches, which tend to have a toolish, stripped-down look. By comparison, the 903 is more elaborate and, given its associations with the design, a more Swiss-luxury aesthetic. With that said, as Sinn is Sinn, they bring their engineering flair, while also keeping the price relatively approachable. This is true for the general 903 models, but even more so for the 65th anniversary model, the 903 Ti II Anniversary.
Interestingly, you’ll see the number two in the name, because Sinn actually made a previous version of a 903 in titanium for its 35th anniversary. Why the 903 and why titanium? Well, we don’t know, but it’s certainly a welcome metal for this watch, and, as it’s been 30 years, a welcome return. Sinn uses grade five titanium for the case and the five-link bracelet, which has a bright, steel-like look that can be polished, while still benefiting from titanium’s light weight.
