We have made sophisticated refinements to the models in our 356 series, which are designated by the suffix Sa.
The tastefully dimensioned case with a diameter of 38.5 mm has a fine satinized finish and gives an impression of high-quality, elegant functionality. Connoisseurs will immediately notice another subtle detail: the high-domed sapphire crystal glass used in the series has the same profile as the acrylic glass in the basic model. This sophistication has its price: in a complex process, the glass must be ground out of a solid blank with a thickness of five millimeters, with five different radii of curvature. The result not only preserves the classic look of these pilot's chronographs, but the glass is also more solid, stronger and more resistant than a simple, flat-ground alternative.
The anti-reflective coating on both sides facilitates accurate reading of the distinctively designed dial even under extreme lighting conditions. We have also enhanced the back of the watch: a sapphire crystal glass back affords a fascinating view of the interior. This is intentional, as the movement has been exquisitely decorated with a tasteful finish and blued screws.
