SINN 1739 is an automatic wristwatch with a polished, stainless steel case measuring 39mm diameter and a minimalistic two hands dial layout. In 2020, SINN added three new variants: 1739 St I 4N, 1739 St I S and 1739 Heimat. These timepieces are equipped with SW300-1 self-winding movement.
The 1739 St I 4N model boasts stylishly arranged golden hands, the appliqués, meticulously attached by hand and the silver electroplated dial with sunburst decoration.
The 1739 St I S watch features an electroplated black dial with sunburst decoration, silver hands, and appliqués, meticulously attached by hand.
The SINN 1739 Heimat pays homage to the brand’s home city, Frankfurt am Main. The extremely fine rhodium-coated relief dial is inspired by the traditional diamond pattern of Frankfurt’s popular cider glasses, also known as Gerippte. The three-dimensional diamond pattern creates an incredibly vibrant interplay of light and shade on the cider glasses.
The relief on the dial is just as vibrant and three-dimensional with a wide range of surface characteristics – from polished to matte silk. The effect is a result of the electroforming technique used in the production process. This method allows complex three-dimensional surface structures to be achieved with a high degree of precision.
The relief dial of SINN 1739 Heimat watch is coated with rhodium, a precious metal similar to platinum, which gives the dial an exquisite silver-white shine.
These highly exquisite and elegant watches, with a diameter of 39 mm, illustrate a sense of tradition. Waterproof and pressure-resistant to 10 bar, the case is reinforced by the slightly curved, high-quality sapphire crystal. The transparent case back made of sapphire crystal glass enables the wearer to admire the self-winding movement.
