The Circula ProTrail Power+ is a 40 mm German-made field watch with a Swiss automatic movement, a no-date dial, and manufacturer-listed resistance to water and magnetic fields. Circula positions it as a modern take on historic military field watches, for outdoor activities, travel, and everyday wear. Its defining choice is the field-watch layout; the brand’s ProFlight uses a pilot-watch design instead.
What is the Circula ProTrail?
The ProTrail Power+ is Circula’s modern field-watch model. The company says its design draws on historic military watches, including the Dirty Dozen, while adapting the idea for contemporary outdoor use, travel, and daily wear. The dial combines 12- and 24-hour markings with luminous hands and indices; the overall styling is deliberately tactical. These are Circula’s design and positioning claims, not findings from independent testing.
The US product listing identifies the black version as product number PT-SS-SS and says it is produced in Pforzheim, Germany. Its Sellita movement is Swiss-made: the watch’s stated German production and the calibre’s Swiss origin refer to different parts of its manufacture.

Construction and features
Circula lists a screw-down crown, screw-in caseback, and soft-iron cage. The maker claims antimagnetic protection up to 80,000 A/m and surface hardness up to 1,200 Vickers for the case and bracelet. Those figures describe the manufacturer’s claims; no magnetic-field or scratch testing was conducted independently here.
The hands and indices are filled with Super-LumiNova, and the dial has no date position. The movement supports hacking seconds, manual winding, and bidirectional rotor winding. The stated 65-hour reserve is Circula’s typical figure; the company also gives a 60-hour minimum.

At 40 mm across and 46 mm from lug to lug, the listed dimensions offer useful starting points for comparing the watch with one you already wear. The 20 mm lug width and quick-change system make other straps a possibility, but check attachment details and strap length rather than assuming every 20 mm quick-release strap will fit.
ProTrail or ProFlight?
Circula describes the ProTrail and ProFlight as sharing a technical foundation but having different design identities. The choice is primarily about dial language and the kind of watch you want on your wrist, not an established difference in tested performance.
