Borrowed from Sinn:
"With its simple elegance and classic design, Model 1746 Classic is the perfect symbol of style. The clear focus on hour, minute and date in a window is one of the most striking characteristics: nothing distracts from the classic design of the case. This visual impression is underscored by the pure white vitreous enamel dial of especially high quality. The logo 'Sinn Frankfurt am Main' is at once the indication of origin and proof of quality. With its tasteful restraint, it leaves plenty of room for the Roman numerals on the dial ring, thus enabling optimal readability.
Model 1746 Classic enchants its wearers with its elegance and technical sophistication. The case is made of polished stainless steel, while the scratch-resistance, high-domed sapphire crystal glass has an anti-reflective coating on both sides. The transparent sapphire crystal glass back with its interior anti-reflective coating gives you an impressive view of the exquisitely decorated movement with blued screws. And as expected, the watch is ideally suited for everyday use: it is shock-resistant, anti-magnetic, water-resistant, pressure-resistant to 10 bar (corresponds to 100 m water depth) and low pressure resistant."
