Circula ProTrail Black Old Radium LE

All about the Circula ProTrail Black Old Radium LE

Field Watches were originally designed for military use and are specifically tailored to the requirements of ground troops. Their main feature is uncompromising functionality and exceptional robustness, which makes them ideal for outdoor activities such as hiking, swimming or mountain biking.

Compared to pilot or diving watches, field watches do not have an elaborate bezel. Classic models are often simple three-hand watches without a date display, but with a practical 24-hour division on the dial.

Our Circula ProTrail is also antimagnetic up to 80,000 A/m, thanks to a special soft iron cage. This makes them insensitive to magnetic fields from smartphones, laptops and other electronic devices that could affect accuracy. By using Super-LumiNova® on the hands and numbers/indices, the time can be easily read even in the dark.

The durable canvas strap is a custom-made product that ensures a secure hold on the wrist and is comfortable to wear. Another special feature of the Circula Field-Watch is the housing made of 316L stainless steel, which is extremely robust and scratch-resistant up to 1,200 Vickers thanks to a special surface treatment.

The Circula Field-Watch is also ideal for use in water. It is waterproof up to 15 ATM and is equipped with a screw-down crown. This robust field watch from Circula is the perfect companion for every adventure!

The ProTrail is an authentic field watch that is characterized by its robustness, functionality and high-quality workmanship. Its carefully hand-sandblasted stainless steel case protects the precise Swiss movement and is antimagnetic up to 80,000 A/m, making it particularly resistant to magnetic fields. Thanks to the scratch-resistant sapphire crystal and a special surface treatment of the case, the watch offers outstanding longevity and resistance

The ProTrail was developed together with over 6,500 voices from the global watch community and therefore offers the highest quality and functionality. A special variant of the watch is the Black Old Radium LE, which is limited to 99 pieces and has a unique dial design and a black-coated case. The Micro Praha LE, another limited version of 50 pieces, was created in collaboration with a watch club from Prague and stands out with its exclusive design.

This field watch from the traditional Pforzheim brand stands for quality Made in Germany and is equipped with the Swiss automatic movement Caliber Sellita SW200-1 Elaboré. The watch is antimagnetic up to 80,000 A/m thanks to a soft iron cage and offers a scratch-resistant surface with up to 1,200 Vickers thanks to a special surface hardening. The hands and indices are equipped with Swiss Super-LumiNova®, which ensures good readability in poor lighting conditions. With water resistance of up to 150 meters and a screw-down crown that also lights up, the ProTrail is well equipped for various adventures. The case has a diameter of 40 mm, a length of 46 mm horn to horn and a height of 12 mm.
