Nautieko Openheart Silver Black

The Nauteiko Openheart Silver Black Roman combines an elegant design with a contemporary and sophisticated touch thanks to its black open-heart dial, which reveals the heart of the automatic movement in operation. Its 41 mm case in 904L stainless steel provides solidity and refined style, while the contrast between the deep black dial and silver details conveys strength and exclusivity.

This watch stands out not only for its striking aesthetics but also for the quality of its materials. The 904L steel strap ensures resistance and a high-end finish, and the anti-scratch sapphire crystal guarantees impeccable clarity. Equipped with the NH38 automatic movement, known for its reliability and smoothness, this design is perfect for those who value both design and precision.
