The Movement

St. Petersburg is powered by an automatic movement adjusted in-house. The whole process for creating these movements is carried out by hand. A well-made movement for a high-quality watch. The 21,600 VPH movement achieves a happy medium between accuracy and durability. High enough that it provides punctual timekeeping and low enough that the movement will be well-preserved for years and years to come. Moreover, the watch is equipped with an Incabloc shock protection system, which we will explain in more detail below.

The Incabloc Shock Protection System

The fragile pivots of the wheel are protected from damage by the Incabloc shock protection system, also known as a spring-loaded mounting system for the jewel bearings that support the balance wheel of a mechanical watch, in the event of a physical collision, such as when the watch is accidently dropped. This innovation was made in 1934 by Swiss engineers Fritz Marti and Georges Braunschweig. Compared to their support mass, pivots, and jewel bearings that provide support to a watch’s balance wheel are fragile and vulnerable to damage upon impact if not protected. This is where the Incabloc shock protection system plays its role.

The mechanism employs a spring that has a shape resembling that of a lyre to enable the delicate bearings to shift within their settings when subjected to impact. This movement continues until a more robust section of the staff comes into contact with the sturdy metal end piece, which relieves the pivots and bearings from bearing the majority of the force. After the force of the impact goes away, the springs lead the components back to their initial positions. It is important to note that while the jewel bearing remains stationary, it is housed in a metal bushing that has freedom of movement within the metal end piece under spring control.

The Dial

St. Petersburg comes with a skeleton dial. Apart from the square case, the skeletonized face is what attracts the most attention. The golden Roman numerals are assembled together with a black skeletonized frame, the Theorema logo, and 4 blue screws. The skeletonized hands are bold and modern, showcasing a three-color design with black, red, and white. The see-through golden dial ties the whole color scheme together. The golden bezel showcases 4 golden screws, preserving the bold and authentic aesthetic.

The Case and Band

The rectangular (almost square) case is made from high grade stainless steel. It comes in a gold color which adds warmth and vibrance to the overall look. The polishing (22 karat gold) is performed exceptionally well, as the case delivers amazing shine and a clean and smooth surface area. Its open back composition allows for a clear view of the moving mechanisms in the back. The blue screws and rubies of the movement add a nice touch of color that pairs well with the rest of the watch’s details. St. Petersburg is paired with a brown leather band featuring a faux crocodile pattern. The light beige stitches are symmetrical and even, while the inner side of the band showcases the Theorema logo.

The Feel

Wearing St. Petersburg is an experience of its own. The leather band feels soft to the touch and yet it provides a sturdy and secure fit. The watch feels comfortable with a weight that doesn’t annoy you, not even once throughout the whole day. Whenever I accidentally throw a glance at the watch, I am satisfied with the way the dial catches the light. The skeletonized face really demands attention. If you need to adjust the time, the rugged crown allows for ease of use. The clasp is durable and easy to do and undo.

The Look

You can style St. Petersburg with pretty much any outfit, and you’re sure it will elevate your look. The skeletonized aesthetic creates an aura of elegance and luxury, making this a perfect timepiece for fancy events. Meanwhile, the brown leather band complements any casual attire. The unique blend of elements gives St. Petersburg a chic feel, allowing you to wear this timepiece with modern outfits as well. I’d say this is one of the most eye-catching and versatile pieces in my collection yet.
