Encased in a 40mm surface-hardened steel, this German-engineered timepiece from Pforzheim boasts a design that is both serious and subtly playful. The ProSea exemplifies Circula's renewed design language, offering a distinctive aesthetic and superior durability at an accessible price point.

Detailed Review of the Circula ProSea Watch

In December 2025, Circula unveiled its latest addition to the Pro series, the ProSea, a professional dive watch drawing inspiration from the majestic manta ray. Headquartered in Pforzheim, Germany, Circula, a family-owned brand, sought to capture the essence of marine life on the wrist. The ProSea features a 40mm faceted case crafted from surface-hardened steel, boasting a remarkable 1,200 Vickers hardness, ensuring exceptional scratch resistance. This robust construction is paired with a manageable thickness of 11.7mm and a lug-to-lug length of 46mm, making it comfortable for a variety of wrist sizes.

The centerpiece of the ProSea is its innovative dial, which accurately reproduces the textured skin of a manta ray. This unique design element, unlike many nature-inspired watch dials, requires no stretch of imagination to appreciate its aquatic connection. The dial is available in an eye-catching petrol blue-green hue, with options for black with blue accents and an all-blue model, catering to diverse preferences. Large, applied markers are subtly integrated into the rehaut, enhancing readability. For low-light conditions, the indices, hour, and seconds hands are treated with blue Swiss Super-LumiNova BGW9, while the minute hand and bezel feature green C3 X1 lume, creating a distinctive two-tone glow.

The watch's functionality extends to its unidirectional rotating bezel, which provides 120 crisp clicks and features knurling that mirrors the unique recessed texture of the mid-case. Powering the ProSea is the reliable Sellita SW200-1 automatic movement, in its Elaboré grade. This movement offers a minimum of 38 hours of power reserve and operates at 28,800 vibrations per hour, precisely adjusted in Pforzheim to maintain accuracy within -5/+7 seconds per day. The movement is protected by a screw-down caseback adorned with an engraved manta ray, further reinforcing the watch's theme.

The ProSea is offered with either a strap or a stainless-steel bracelet. The bracelet, a classic three-link design, complements the case's angular aesthetics with its sandblasted finish, quick-release spring bars, and tool-free micro-adjustment clasp. The 20mm lug width allows for easy strap changes, and the angular case design includes a subtle shelf between the lugs, ensuring a seamless fit with various strap choices. Starting at €1,090 on a strap and €1,290 on a bracelet (including VAT), the Circula ProSea offers exceptional value for a German-made dive watch that combines distinctive design with practical durability.

The Circula ProSea serves as a compelling reminder that innovation in watchmaking doesn't always require reinventing the wheel but can come from fresh perspectives on established concepts. Its manta ray-inspired dial is more than just a decorative element; it embodies a deep connection to nature, translated into a functional and aesthetically pleasing design. This timepiece encourages watch enthusiasts to look beyond conventional designs and appreciate the artistry and engineering that goes into creating a truly unique product. It highlights Circula's commitment to quality and distinctiveness, proving that remarkable watches can be both robust and imaginative, and accessible without compromising on character.
