Sinn 1739 Ag B
Reference: 1739.021

Perfect elegance, in solid silver with oxidation protection

This is a stunning timepiece for the modern aesthetic who appreciates both quality watchmaking and meticulous, understated design.

An inherent combination of watchmaking craftsmanship and distinctly traditional aesthetics defines the style of Sinn’s elegant 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.

To capture the classic nature of this two-handed watch, Sinn has designed a case made of a 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 (provided with each watch). Because Sinn understands that the mechanics of the movement are just as important as looking at the dial for many watch lovers, the 1739 Ag B is equipped with an exhibition case back made of sapphire crystal glass. This exceptionally beautiful timepiece is water-resistant and pressure-resistant up to 10 bar (100m) as well as being resistant to low pressure, ensuring long-lasting enjoyment and performance.

Our Tip: Add in each band option to your purchase to give yourself several different and striking looks that complement the brilliant blue dial.
