Cestrian Field Series Automatic Green Dial NATO Strap Men’s Watch CF321N5660

The Cestrian Field Series is a rugged automatic timepiece engineered for versatility and everyday endurance, drawing on classic field-watch design with modern robustness and clear legibility. Its purposeful aesthetic and durable construction make it suitable for both urban environments and outdoor adventures, reflecting a blend of practicality and refined detail. 

A Movement Built for Reliability
At the heart of the Field Series is the Seiko NH35 automatic movement, a trusted mechanical calibre offering approximately 41 hours of power reserve and the ability to be wound by both motion and manual crown winding. It features a hacking function for precise time setting and maintains reliable accuracy typical of field watches, making it dependable for everyday use.

A Dial Inspired by Classic Field Watches
The dial is presented in a range of tones and features a straightforward layout with prominent 12- and 24-hour Arabic numerals treated with C3 Super-LumiNova® for vibrant legibility in low light. Polished nickel arrow hands also luminous contrast with the dial, while a 60-second track around the chapter ring supports accurate time reading. A bold coloured seconds hand adds a touch of visual character. 

Robust Construction and Durable Materials
Housed in a 316L stainless steel case measuring approximately 40mm with a slim profile, this model balances strength with comfort. The screw-down crown adorned with the brand’s shield logo and a closed case back contribute to the watch’s impressive 200 metres water resistance, making it suitable for wet conditions. A sapphire crystal with anti-reflective coating protects the dial against scratches and maintains clarity.

Crafted for Everyday Versatility
The Field Series is offered with either a fully brushed stainless steel bracelet secured with a safety deployment Z-clasp and micro-adjustments, or a lightweight NATO strap for a more rugged feel. The combination of reliable automatic performance, robust materials and a clear, classic dial design makes this timepiece a versatile companion for daily wear and outdoor pursuits alike.
