NAUTEIKO Rose Gold Open Heart – Sapphire Crystal | NH38 Automatic

This handcrafted NAUTEIKO Open Heart model blends refined elegance with mechanical character. The rich brown horizontally brushed dial is complemented by an open-heart aperture, revealing the balance wheel in motion for a striking and sophisticated visual effect.

The watch is powered by the reliable NH38 automatic movement, chosen specifically for open-heart designs thanks to its clean no-date configuration. A rose gold–tone brushed stainless steel case, integrated bracelet, and scratch-resistant sapphire crystal complete this luxury-inspired timepiece.
