Cestrian Field Series Automatic Green Dial Green NATO Strap Men’s Watch CF321N5660
The Case:
The Cestrian Field Series CF321N5660 prioritises versatility and functionality. It is made from black sand-blasted PVD stainless steel that not only enhances the aesthetics but also significantly improves the performance of stainless steel by increasing wear, scratch, and corrosion resistance. It measures 40mm in width and has a slim profile of 12.20mm, providing both style and practicality. The case exhibits a combination of brushed and polished finishes, adding an element of sophistication to its robust build. One of the watch’s standout features is its’ screw-down, which helps to provide it with its 200 metre water resistance rating. The crown is embellished with the Cestrian shield logo and has knurled edges to ensure that it is easy to operate. It also features highly scratch-resistant sapphire crystal glass that has been treated with an anti-reflective coating, to ensure that it always remains readable. The case is secured through the closed case back that proudly displays the Cestrian shield logo as well as the unique serial number.
The Dial:
The dial is presented in a matte green hue, instilling a rugged charm and a subdued, military-inspired aesthetic that exudes durability and practicality. It showcases an uncomplicated layout that remains true to the design of a classic field watch. It displays a 12/24 hour format through printed Arabic numerals that have been treated with a C3 Super-LumiNova coating, which emits a vibrant green glow in low light. The polished nickel arrow handset also features a luminous coating, while the vibrant tone of the orange seconds hand matches the ‘Dive Series' inscription. A 60-second track is located around the edge of the dial on the chapter ring.
The Strap:
The watch is presented on a green nylon NATO strap that offers comfort and durability, whilst also remaining true to the watch’s classic military aesthetic. The strap can be adjusted to fit your wrist through a pin and buckle mechanism.
The Functions:
Powered by Seiko's NH35 automatic movement, the Field Series offers a 41-hour power reserve and -20/+40 seconds per day accuracy. The bi-directional rotor charges the movement through motion and manual winding via the crown. Hacking allows precise time setting. With an impressive 200 metres of water resistance, this watch is ideal for adventurous field activities.
