Circula SuperSport Petrol Review: A Genuine Super Compressor Diver Under $1,000

There is something undeniably romantic about vintage dive watches. As a watch enthusiast, I am always on the lookout for pieces that offer a distinct personality without demanding five-figure investments. The “Super Compressor” style has always been an incredibly interesting angle for me, channeling a strong vintage vibe that instantly sets it apart from external-bezel divers. But while many modern watches merely copy the dual-crown look of classic compressors, Circula has gone a step further to deliver a genuine, functional super compressor. Let’s dive deep into this German-engineered beauty to see if it deserves a spot in your collection.

Brand Overview

If you haven’t heard of Circula yet, you are missing out on one of the best-kept secrets in modern horology. Based in Pforzheim, Germany - a city with a rich jewelry and watchmaking heritage - Circula is a thoroughly under-the-radar brand that has been quietly crafting high-quality timepieces since 1955. Today, the brand is revived and run by Cornelius Huber, the grandson of the original founder. Cornelius has done a masterful job of blending modern independent watchmaking sensibilities with democratic design, often opening up choices to the global watch community through votes.

What I love most about Circula is that they remain exceptionally reasonably priced while refusing to cut corners on execution. They have also developed a reputation for creating visually strong, unforgettable dials. In fact, that eye-catching design language is why another personal favorite of mine from the brand is the rugged Circula DiveSport Titanium Petrol, a watch that completely redefines what a modern titanium tool watch can look like. With the SuperSport line, Circula pairs that same mastery of color with historical engineering.

Watch Overview

The Circula SuperSport Petrol is a sports watch that immediately catches the eye with its dual-crown configuration. Historically, true super compressor cases used a spring-loaded mechanism where the increasing water pressure actually compressed the case back against the gasket, sealing the watch tighter the deeper you went. Circula brought this exact functionality back to life, offering a true compressor build with an impressive 300 meters of water resistance.

From an aesthetic standpoint, it masterfully strikes a balance between a robust tool watch and an elegant daily wearer. It avoids the bulky, overbuilt feel of many 300m divers by keeping the geometry sharp, angular, and incredibly compact. It feels solid, purposeful, and brimming with mid-century maritime character.

Dial

The dial color on this watch is nothing short of mesmerizing. “Petrol” is a hue that Circula has absolutely perfected - a deep, complex teal that sits right on the border between ocean blue and rich emerald green. Under direct sunlight, a subtle sunburst effect catches the light, shifting the tone dynamically. In low-light environments, it tones down to a moody, sophisticated dark sea green.

Circula opted for a sophisticated sandwich construction here. The hours indices are cut out from the upper layer, revealing a lower luminescent floor filled with Swiss Super-LumiNova BGW9, which glows a brilliant, crisp blue. I particularly love the playful “rabbit’s teeth” dual index at the 12 o’clock position, giving the dial an extra punch of retro charm. The brushed hands match the case finishing beautifully, ensuring that legibility remains top-tier regardless of the lighting conditions. The date window at 6 o’clock is flawlessly executed with a color-matched date wheel, preserving the dial’s symmetry.

Bezel

Since we’re looking at a super compressor dive watch, instead of a traditional external rotating bezel, the SuperSport features an internal rotating diver’s bezel, adjusted via the dedicated crown at the 2 o’clock position. What makes this implementation special is that while classic compressors usually feature a friction-fit, bi-directional internal bezel, Circula engineered a 120-click, unidirectional internal bezel.

The tactile action when you turn the 2 o’clock crown is satisfyingly clicky and precise, reflecting serious German engineering. The internal bezel markers are coated in Swiss Super-LumiNova C3 X1, which glows green. This creates a brilliant, two-tone light show when transitioned into the dark - blue for the dial indices and green for the timing bezel. My only slight critique is that the yellow accents on the first 20 minutes of the inner bezel track don’t pop quite as brightly in total darkness as the white sections do, but it’s a minor quirk in an otherwise spectacular layout.

Case

When it comes to wearability, the dimensions of the SuperSport are absolutely fantastic. Measuring 40mm in diameter, 46.5mm lug-to-lug, and just 12mm in height (13.3mm with the slightly domed sapphire crystal), it offers a near-universal good fit for all wrist sizes. On the wrist, the short, angular lugs allow the case to sit beautifully flat, feeling incredibly balanced and compact.

The 316L stainless steel case features meticulous hand-brushed finishes on the top and sides, separated by a crisp, polished bevel that adds a touch of refinement. The dual crowns are beautifully detailed; the 4 o’clock winding crown is screw-down, engraved with a Circula logo, and accented with a distinct inlaid brass ring. Flip the watch over, and you are greeted by an embossed case back featuring a vintage diving helmet resting on top of a wave pattern - a lovely nod to the compressor heritage of the 1950s.

Movement

Pop the hood, and you will find the Swiss automatic Sellita SW200-1 in its upgraded Elabore grade. Seeing a regulated, high-beat Swiss automatic movement inside a watch under $1,000 is an absolute steal in today’s market.

Circula goes the extra mile by fine-adjusting the movement right in their Pforzheim workshop, tuning it to an impressive accuracy of -5/+7 seconds per day. Featuring 26 jewels, a smooth 28,800 vibrations per hour, and Incabloc shock protection, it is a bulletproof, reliable workhorse. The winding action through the crown feels silky smooth, and the inclusion of hacking seconds makes setting the precise time a breeze.

Strap

The SuperSport Petrol comes standard on a color-coordinated, Tropic-style rubber strap equipped with a quick-change system. The rubber is remarkably soft, pliable, and comfortable right out of the box, avoiding that stiff, plasticky feel common with cheaper microbrand straps. The basketweave texture and perforations enhance the vintage diver look perfectly while allowing the wrist to breathe.

Comparison: Circula SuperSport vs. Le Forban Rochelaise

Since Circula’s site says “Final models in stock”, and I can’t confirm if this model will be available again soon, I wanted to provide an alternative that’s also very under-the-radar: another prominent European contender, the Le Forban Securite Mer Rochelaise, which I previously explored in the Le Forban Rochelaise Review.

Both watches boast historic maritime roots and feature an internal bezel system operated by a secondary crown to capture that iconic retro vibe. However, their execution differs vastly. The Le Forban Rochelaise adopts a softer, 39mm cushion/turtle case shape rooted in French skin-diver design. While it is incredibly charming and comes in at a lower, mid-three-figure price point, it is only rated to 150 meters of water resistance and lacks the true spring-loaded compression mechanics of the Circula. Furthermore, the Rochelaise relies on a Japanese Miyota automatic movement, whereas the Circula steps up to a highly regulated, premium Swiss Sellita SW200-1 Elabore calibre.

If you are looking for pure retro styling on a budget, the Le Forban is a lovely piece. But if you want authentic super compressor engineering, a superior Swiss heart, and highly technical case finishing, the Circula justifies every bit of its slightly higher price tag.

Pros and Cons

Pros

• Genuine compressor case: A functional super compressor case with 300m water resistance.
• Dial execution: The mesmerizing Petrol dial with its sandwich construction offers incredible visual depth.
• Fantastic dimensions: Universal proportions that flatter almost any wrist size.
• Movement value: Exceptional value for a fine-tuned Swiss Sellita SW200-1 Elabore movement under $1,000.

Overall Takeaway

The Circula SuperSport Petrol is a masterclass in how to successfully execute a vintage homage for the modern enthusiast. It doesn’t just rest on the laurels of its gorgeous looks; it backs them up with true super compressor engineering, immaculate German regulation, and a flawless Swiss movement. Circula continues to fly under the radar for casual buyers, but for connoisseurs who appreciate robust specifications, striking dial colors, and genuine horological value, this watch is an absolute home run. If you want a diver that stands out gracefully from the crowd, this final batch of the SuperSport Petrol is worth snapping up before it is gone for good.
