Ulysse Nardin 1183-170-2B/3A Diver NET Azure 44mm Black Dial Watch

Ulysse Nardin Diver Net Azure 44mm – Ref. 1183-170-2B/3A

Boldly sustainable, technically advanced, and made for the ocean — the Ulysse Nardin Diver Net Azure (Ref. 1183-170-2B/3A) is a groundbreaking dive watch that fuses marine DNA with pioneering eco-conscious innovation. Developed as part of the brand’s environmental commitment, this 44mm timepiece is constructed using materials sourced from the sea and advanced composites, all while delivering professional-grade dive performance.

Eco-Innovation at Its Finest

The case is crafted from recycled stainless steel and features side elements made of Nylo® — a sustainable polyamide made from upcycled fishing nets. The unidirectional rotating bezel is composed of Carbonium®, a cutting-edge carbon fiber material used in aerospace engineering, with 40% lower environmental impact than other carbon composites.

Its light weight and exceptional resilience make the Diver Net Azure not only a statement piece but also a true tool watch built to perform in extreme marine conditions. The 44mm case size ensures excellent readability underwater while retaining wearability for daily use.

Distinctive Design with Azure Accents

The sandblasted black dial provides a matte finish that reduces glare and enhances visibility. Bright azure-blue accents appear throughout — from the signature “X” motif to the power reserve indicator, seconds track, and stitched rubber strap. This splash of blue evokes the spirit of the open ocean while reinforcing the watch’s environmental message.

The oversized hands and indexes are coated with Super-LumiNova® for enhanced legibility in low-light diving scenarios. A date window is positioned at 6 o’clock, and a power reserve indicator at 12 o’clock keeps the user informed of the watch’s performance at a glance.

Precision Inside and Out

At 1183-170-2B/3A heart beats the in-house UN-118 automatic movement with a 60-hour power reserve. Engineered for durability and precision, it features Ulysse Nardin’s proprietary silicon escapement and balance spring, and DiamonSIL® technology for added resistance to wear and magnetism. This movement is a testament to the brand’s horological innovation and is visible through the sapphire exhibition caseback.

Designed for Professional Diving

The Diver Net Azure is water-resistant up to 300 meters (1000 feet), making it suitable for serious diving adventures. The screw-down crown and robust construction ensure security and longevity even in the harshest aquatic environments.

Azure Rubber Strap with Ceramic Elements

The watch is fitted with a durable, textured azure-blue rubber strap that offers excellent comfort and flexibility. It’s equipped with ceramic components at the pin buckle and loop for increased durability and a modern aesthetic.

Conclusion

The Ulysse Nardin Diver Net Azure Ref. 1183-170-2B/3A is more than a diver — it’s a symbol of responsible luxury. With sustainable materials, innovative mechanics, and a design inspired by the ocean, it stands as a beacon for the future of Swiss watchmaking.
