The defining feature of the Alsta Nautoscaph Bronze Porcelana is its rich brown dial, inspired by warm chocolate and earthy tones. The distinctive colour complements the natural warmth of the bronze case, creating an appealing contrast with the black ceramic bezel. Prominent Arabic numerals, applied hour markers and tapered sword hands preserve the highly legible appearance of the Nautoscaph collection, while C3 Super-LumiNova ensures excellent visibility in darker environments. A date display completes the dial, providing practical everyday functionality.

The 40mm case is crafted from high-grade bronze, a material prized for its distinctive appearance and ability to develop a unique patina over time. Measuring 51.3mm lug-to-lug and 16.2mm thick, the watch offers the substantial proportions of a traditional diving instrument. A unidirectional rotating steel bezel with black ceramic insert, scratch-resistant sapphire crystal and screw-down bronze crown provide robust construction. The engraved stainless steel caseback and 300 metre water resistance complete the technical specification, while the brown leather and Alcantara-style strap reinforces the watch's sophisticated colour palette.

The movement provides central hours, minutes, seconds and a date display, supported by shock-resistant construction and ISO 764 anti-magnetic protection. The watch is presented in a premium corn leather and Alcantara presentation box, reflecting the considered approach to materials and craftsmanship throughout this limited edition.
