The Circula ProTrail Power+ is a 40 mm automatic field watch with a 15 ATM water-resistance rating and a Sellita SW200-2 Power+ movement. CiRCULA lists a typical 65-hour power reserve and claims magnetic shielding up to 80,000 A/m. Those are manufacturer specifications, not independently verified test results; the available evidence does not establish hands-on comfort, accuracy, or durability.
What the Circula ProTrail Power+ is
CiRCULA describes the ProTrail Power+ as a modern German field watch inspired by historic military field watches, including the “Dirty Dozen” category. That is a design reference, not evidence that the ProTrail was military-issued or has a historical lineage. The brand emphasizes legibility, with luminous numerals and hands, a layered dial, and a sandblasted, hardened stainless-steel case. These are the manufacturer’s descriptions rather than independent design or durability assessments. CiRCULA’s product listing and feature page provide its specifications and positioning.

CiRCULA also specifies a soft-iron cage and claims magnetic shielding up to 80,000 A/m. It lists surface hardness of up to 1,200 Vickers for the case and bracelet. These figures describe the maker’s claims; no independent magnetic-resistance or hardness testing is established here. The official product listing is the source for the dimensions and technical details.
Dial, fit and everyday use
The 40 mm diameter and 46 mm lug-to-lug measurement give a more useful starting point for assessing fit than diameter alone. The case height is listed as 12.3 mm including the glass. Actual wrist presence and comfort depend on wrist shape, strap, and preference, and no hands-on fit assessment is available here.

#1 Best Overall
- SOLAR POWERED — NO BATTERY SWAPS, EVER — Casio's solar-recharging system converts even faint light from fluorescent lamps into ample energy to achieve stable operation of various high-load functions — meaning the MTP-S120L stays powered through normal indoor and outdoor use indefinitely. Operating time from a full charge runs approximately 8 months without any additional light exposure, making it one of the most maintenance-free everyday analog watches available.
- STAINLESS STEEL CASE WITH MILITARY-INSPIRED NYLON STRAP — The 42mm stainless steel case features a solid caseback and fixed bezel, paired with a 22mm nylon NATO-style strap with a buckle closure. The fabric band has a backing just like a proper military strap — a purposeful, field-watch aesthetic that pairs naturally with the black or olive colorways and fits the 22mm lug width for easy strap swaps.
- DAY & DATE DISPLAY | 24-HOUR INNER BEZEL | LUMINOUS HANDS — The black dial features hour, minute, and second hands, a day and date display, and a 24-hour inner chapter ring. Luminous hands ensure readability in low-light conditions — a practical field-watch detail that keeps the time visible after dark without a backlight. Mineral glass protects the dial from everyday scratches.
- 100M WATER RESISTANT | SCREW-ON CASEBACK | 42MM STAINLESS STEEL — Water resistant to 100 meters (10 ATM), with a stainless steel case measuring 42mm in diameter. The caseback is screw-on, providing additional movement protection — a construction detail typically found on watches at a significantly higher price point. Push-in crown completes the clean, purposeful profile.
- FIELD-WATCH VERSATILITY — NATO STRAP-READY & EVERYDAY CAPABLE — The MTP-S120L is great for a grab-and-go everyday watch — stainless steel case, solar powered, day/date, and thin enough where a NATO strap doesn't make it look too thick on the wrist. Available in Black (MTP-S120L-1AV) and Green (MTP-S120L-3AV) colorways — both built on the same proven solar platform.
The field-watch layout includes 12- and 24-hour indications, with luminous hands and numerals described by CiRCULA. Those features suggest a dial designed to make time-reading straightforward, but legibility in particular lighting conditions has not been independently evaluated. The stated 20 mm lug width gives a nominal strap size; check the attachment design before buying a third-party strap, since the listing’s quick-change description does not establish compatibility with every 20 mm strap.
The 15 ATM rating, sapphire crystal, and screw-down crown are useful listed specifications, but they should not be confused with independent water, impact, or scratch testing. Likewise, the published -5/+7 seconds-per-day accuracy is a manufacturer specification, not a measurement of a sample watch over time.

Movement and power reserve
The ProTrail uses a Sellita SW200-2 Power+ automatic movement. CiRCULA lists a minimum power reserve of 60 hours and a typical reserve of 65 hours. The distinction matters: 65 hours is the advertised typical figure, not a guaranteed minimum. The available product information does not establish independent measurements of reserve or long-term accuracy.
ProTrail vs. ProFlight Power+
CiRCULA positions the ProFlight Power+ as the adjacent alternative, sharing a technical foundation with the ProTrail but using a pilot-style dial with an orientation triangle. The ProTrail instead has a field-watch layout with 12- and 24-hour indications. The maker’s positioning is not an independent comparative test.

Price and availability depend on market
The official US listing reports a price of US$1,090 plus US$99 for duties, fees, and shipping, and says preorder delivery begins in October. A separate official locale listing reports €1,090 including VAT and worldwide shipping. CiRCULA’s feature page says a next shipment was expected in early September 2026. These listings do not establish current stock or delivery timing as of 7 October 2026, so confirm the live checkout details or contact the seller before ordering. The US and euro figures are not directly comparable without accounting for tax, import charges, shipping, currency, and the date of the listing.

What is and is not established about the watch
CiRCULA hosts a feature about reviewer Teddy Baldassarre examining the ProTrail’s comfort, case, dial, strap, and craftsmanship. The available page gives topic headings and video timestamps, but not a complete independent transcript or independently measured results. It should not be treated as a hands-on test for this review. No independent long-term accuracy, comfort, impact, water-resistance, or magnetic-resistance test is established here.
On the information available, the ProTrail Power+ is a specification-rich automatic field watch whose clearest practical differentiators are its 40 mm case, 15 ATM rating, 12-/24-hour dial layout, and maker-claimed magnetic shielding. Whether those claims and the fit work for a particular buyer cannot be determined from the published specifications alone.
