Nauteiko Openheart Chocolate

The Nauteiko Openheart Chocolatte combines the elegance of its chocolate brown open-heart dial with the robustness of a timeless design. The dial displays a warm and sophisticated tone that contrasts with the silver details, offering an exclusive style that stands out on any occasion. The open-heart window reveals the heart of the automatic movement, providing dynamism and distinction.

The 41 mm 904L stainless steel case offers strength and a premium finish, while the 904L steel strap completes a solid and versatile set. With anti-scratch sapphire crystal, Luminova on hands and indices, and the reliable NH38 automatic movement, this design unites precision, quality, and character in one watch.
