1739 Ag B

An inherent combination of watchmaking craftsmanship and distinctly traditional aesthetics defines the style of our 1739 Ag B model. The eyes are drawn to the electroplated blue dial exquisitely decorated with a sunburst finish. Reduced to a minimum, the design focuses on the essentials – the hour and minute display. The resulting clarity, skilfully combined with the polished, rhodium-plated appliqués meticulously attached by hand, conveys a harmonious overall appearance.

It was therefore only logical for the brand to capture the elegance of this two-handed watch in a case made of special material: 935 Argentium silver alloy. The advantage of this over traditional precious metal is that rather than tarnishing and blackening like normal silver, Argentium forms a protective germanium oxide surface layer. This layer considerably slows down the tarnishing process. Instead, a golden hue develops, which can be removed with an Argentium care cloth.

And because Sinn know that looking at the mechanics of the movement is just as important as looking at the dial for many watch lovers, they have equipped the 1739 Ag B with a transparent back made of sapphire crystal glass. Therefore, just as much attention can be devoted to the fascinating movement as to the watch dial.

This exceptionally beautiful timepiece comes in an elegant case containing two Argentium care cloths. This, in addition to the fact that the watch is water-resistant and pressure-resistant up to 10 bar as well as resistant to low pressure, ensures long-lasting enjoyment of an exceptional timepiece.
