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.
