Circula ProTrail Review: A Field Watch That Overdelivers on Paper

Introduction

Finding a watch that overdelivers on its spec sheet can make for a more compelling package overall. Many watches that deliver strong value are usually well known in the general discourse, but every once in a while there is a watch that is not appreciated as much as it should be by the collector community, often because it comes from a smaller brand. The Circula ProTrail qualifies for that assessment. It comes from a German family-owned company and serves as a complete package for everyday wear on paper, with solid wearability, a strong water resistance rating, a high-grade caliber inside, magnetic resistance, and a scratch resistant case, all while sitting at around $1,000.

Circula has roots in Pforzheim in the Black Forest region of Germany, an important hub for watchmaking in the country. The company is now led by the third generation of the Huber family. Heinz Huber founded the company back in 1955 after working with his family’s watch wholesale business, Huber & Company, which was established in 1926. He took the name Circula as a nod to the circular balance wheel of mechanical movements, a tribute to his passion for the traditions of watchmaking. Circula produced a wide range of quality timepieces with an emphasis on mechanical tool watches, including divers and chronographs.

The quartz crisis took a toll on the company during the 1970s, forcing it to pivot to the production of quartz watches to stay competitive. Heinz’s son, Claus Dieter, led the business from the mid 80s focusing on the wholesale side, but the brand put a new emphasis on watchmaking when the third generation came into the fold. Heinz’s grandson, Cornelius, took the reins in 2019. Under his leadership, Circula repositioned to reach a more collector-minded customer base, beginning with a Kickstarter campaign that started with a core series inspired by historic 1950s designs. Circula then released the Aquasport, their 1970s style dive watch, and it is this model that brought the brand to a new audience, remaining a strong part of their lineup today. The ProTrail, first released in 2022, is the brand’s everyday style watch, serving as a robust offering that delivers on concepts from German standouts like Sinn, with case hardness treatments and magnetic resistance that are among the best in class.

Design and Build Quality

It is clear when you first look at the ProTrail that it is no traditional field watch. The almost brutal angularity of the case has a profile that is thoroughly modern. Its rugged appearance is not just posturing as some tool watch wannabe. The closer you look, the more you recognize that this watch is more of a tool than even it lets on.

The sandblasted stainless steel case undergoes a proprietary low temperature hardening process which diffuses carbon into the surface lattice structure without creating unwanted chromium carbides, preventing surface peeling while maintaining corrosion resistance. The resulting surface boasts a hardness of 1,200 on the Vickers scale, bringing this to way more elevated levels than untreated stainless steel, which has a typical hardness between 150 to 300. This is probably one of the more attainable watches that is getting this case treatment. The most famous in the price range above this would be Sinn with their tegimented cases, but 1,200 Vickers at this price is pretty impressive and something you typically do not see. If you prefer a stealthier look, Circula does offer a model with a black DLC coated case as well.

The dimensions are easy wearing with a 40 mm diameter and a 12.5 mm case height, and a buttoned-up 46 mm lug-to-lug measurement that should give a variety of wrist sizes the ability to pull this one off. The multi-angled surface gives off a sense of aggression with its matte finish offset by a touch of polish on the transitional facet side of the bezel. One of the striking design cues comes from the inset section of the case side, which features an almost pebbled texture, offering a ton of visual interest while reinforcing the watch’s tool-like attitude. The dial is protected by a gently domed sapphire crystal, offering a clear view thanks to double inner anti-reflective coating. The signed screw-down crown helps bring water resistance up to 150 m, an elevated spec for a field watch, and the screwed-in solid caseback features a simple engraving of a topographic map.

Dial and Legibility

Moving to the face of the ProTrail, this is a dial that prioritizes legibility above all else. Several variants are available including gray, a brown tone called umber, an earthy green, basic black, and the most popular from my understanding is the sand colorway, which has a couple of aesthetic differences from the rest.

For the other colorways, the format sticks to the same playbook. At the outer edge, you will find a railway minute track that comes with small lume plots every 5 minutes. Just inside the track are large printed Arabic numeral hour markers also featuring Super-Luminova and set against a matte backdrop. Toward the center of the dial is an Arabic 24-hour scale printed on the concentrically lined background for some added visual interest. Dial text is minimal with the circular word mark below 12 and ProTrail sitting atop anti-magnetic above six. Each colorway uses different accent colors for printed elements, but they all complement their dial colors nicely.

The brush handset is appropriately wide with a profile that resembles a broadsword, ensuring easy reading at a glance. The silver tone hands are filled with the same Swiss lume as the dial markings and the needle second hand is tipped in a coordinating color.

As for the sand colorway, this is where we see some distinct differences in terms of the dial. While the initial versions of the khaki colored dial featured the same inner dial as the rest of the colors, newer versions get a grainy pressed texture that resembles sand. Another difference is that we have heat treated blue hands. They are heated in order for an oxide layer to form on those hands, which is beautiful to look at, but also adds some corrosion resilience to the hands as well. Dial text is done in black and blue that closely matches the hands, bringing a cohesive look to the total package. The final difference is the implementation of lume. While the hands are lumed normally, the dial markings are not. Instead, the outer dial is fully lumed, a small design choice that offers maximum contrast in both day and night settings.

Movement and Performance

The ProTrail features a soft iron inner cage surrounding the movement, which raises the magnetic resistance to 80,000 A/m or 1,000 G. The ISO 764 standard for magnetism in watches only calls for 4,800 A/m, so in other words, the ProTrail delivers a magnetic resistance standard 16 times that of ISO.

The movement used in the ProTrail is the Sellita SW200 caliber. Sellita has since replaced the SW200-1 movement used in the ProTrail with the new SW200-2 caliber, wrapped in the protection from magnets with that soft iron inner structure. The big news is that Sellita has upgraded the power reserve from 41 hours to 65 hours, leveling the playing field with much of the competition. The ProTrail features the Elaboré grade SW200-2 version, which removes the date function so that there is no ghost position with the crown. In addition, the movement is fine adjusted in-house, minus 5 to plus 7 seconds per day.

The SW200 has settled in as more of a drop-in replacement for the ETA 2824-2, as supply of ETA movements to brands outside of the Swatch Group’s umbrella is pretty much eliminated completely nowadays. The Elaboré grade increases the movement finish and has a better stated range of regulation out of the factory. The rate of the caliber is 28,800 vibrations per hour or 4 Hz. It features hacking and hand-winding. Hacking stops the seconds when you pull the crown to the farthest position and has 26 jewels, one more than the ETA 2824. The SW200 also features a Nivaflex alloy mainspring and Incabloc shock protection system and a bidirectional winding rotor.

Strap and Bracelet Options

As far as the wear experience goes, there are both strap and bracelet options for the ProTrail. The strap is made from a color matched nylon canvas and has a reasonably comfortable leather lining on the underside. The strap gets quick release spring bars and a signed stainless steel pin buckle with a matched sandblasted finish, which actually has the same scratch resistant properties as the case. No corners are being cut there.

Likewise, the three link bracelet features the same hardened finish, giving the watch a virtually everything proof build quality. The links are also screwed in for added security. The milled scissor interior of the clasp has an engine turned perlage look and the clasp features dual push buttons and tool free micro adjustment. As an added bonus, if you specify a bracelet with your ProTrail, Circula will throw in a strap as part of the package. And if you do decide to experiment with other straps, the 20 mm lug width is going to keep your options wide open.

Buying Advice

Despite $1,000 not being what it used to be years ago in watches and really just in life in general, it is still a lot of money to spend on anything. The good news is you are not faced with a shortage of options in today’s watch market if your budget is a thousand dollars. Many pieces from the likes of Hamilton, Seiko, Tissot, and a long list of other microbrands are going to be well documented by the community in this range. Deciding on which is right for you is a decision based on logic as well as emotion. Only if you can find a marriage between those two opposing perspectives will you come out with the right choice.

What consistently becomes the leading trait at this tier is this idea of value for money. This unofficial class is often represented by the list of features on a spec sheet where a watch can deliver more than its peers. What makes the ProTrail an interesting talking point and lesson in collecting is that on paper, this watch is maybe the most complete that you will come across for a thousand dollars. Let us recall those specifications here. 150 meters of water resistance, a sapphire crystal with stellar AR coating, a case hardness treatment that will resist scratches multiples of the standard of stainless steel or titanium. You have a soft iron cage with magnetic resistance to 1,000 gauss, stellar lume, heat-treated blue hands, an elevated caliber grade, regulated movement just outside of COSC standards, a robust bracelet with that surface treatment again, milled parts of the components in that bracelet, and you get on-the-fly adjustment to go along with it.

The brand says that the prices of the ProTrail will be $1,090 on the strap with the new movement, and $1,290 on the bracelet. That is around $100 more per version, which seems reasonable considering the movement upgrade.

Conclusion

As great as the Circula ProTrail is, it serves as an important reminder to enthusiasts out there. Watches can wow us with features, and we can often be very quick to make requests of brands to include new features in existing designs. Although, if you look at your collection and ask the question, why do you love a particular watch, the answer is likely not the water resistance or notes on a spec sheet. More so, it is probably your interest in its design, how you identify with a piece and how it expresses you, perhaps the history of the model family, or your sentimental connection to the watch.

On paper, the ProTrail is one of the most capable watches in its class at $1,000. Maybe the most capable. It is impressive what they are able to pack into this watch, and it gives pretty much everything else a run for its money, at least in that regard. But there is more to watches than just that. It should be an element of personal expression, and that should never be a casualty in the pursuit of the best value for money.
