Royal watchmaking complication – Tourbillon. Tourbillon is a mechanism that compensates for the influence of the earth’s gravity on the accuracy of the watch. It is a mechanical anchor mechanism located inside a moving platform with a flywheel in the middle and rotating around its own axis once per minute, thus ensuring a change in the position of the flywheel relative to the earth’s core. It is one of the so-called complications of high watchmaking – Haute Horlogerie. It was invented by A. L. Breguet in 1795. Watches with a tourbillon are offered only by high-quality watch brands and it is a guide for the initial assessment of the quality of the brand.

The chronograph function is one of the most popular watch “complications” or additional functions, and its design is also interesting from an aesthetic point of view. The word chronograph literally means “time writer”. Chronographs are watches with the function of accurately measuring selected time periods, i.e. the watch has an integrated stopwatch function. The chronograph is usually controlled by two crowns. Chronographs can have both quartz and mechanical drives with manual or automatic winding. Mechanical chronographs are generally taller than simple watches, because a complicated movement takes up more space in the watch case. We offer mechanical chronographs every year in limited PRIM series.

– in cooperation with a Swiss manufacturer
Cooperation with a company that produces movements for companies such as the Fossil group has opened up enormous possibilities for us. We offer you the originality and quality that you can find in world brands and now also in PRIM watches.nIn 2006, a small group of entrepreneurs decided to develop mechanical movements and manufacture them in Switzerland. In line with the motto “driven by passion, driven by innovation”, fascinating mechanical movements of excellent quality were created and are manufactured on state-of-the-art assembly lines at the company’s headquarters in Switzerland.

Founded in 1918, Citizen is one of the world’s largest and most respected world-leading manufacturers of watches, fine mechanics and electronics (although used by different brands, their movements are always named Miyota).

A Swiss manufacturer that produces high-quality mechanical movements bearing the name “Swiss Made”. The motto of the company is: “We combine quality, advanced mechanics with Swiss craftsmanship”.

The company was founded by Kintaró Hattori in 1881. Seiko is one of the few fully integrated watch manufacturers – designing and developing their own movements using state-of-the-art technology. Under the Seiko brand, innovative solutions were introduced for electronic watches. In 1969, the company produced its first quartz watches and went on to launch the first quartz chronograph in the following years. The famous automatic chronograph “Seiko 6139” was introduced in 1969.

The group was founded in 1955 and holds the title of the largest manufacturer of mechanical movements in the world. Sea-Gull represents a tradition of production, experience in clockwork, a strong technical background and the technical development of CNC machines for custom-made production. Sea-gull has been awarded an A in the value measurement class and received complete ISO 9001.2000 certification for its quality management and reliability of testing.

Ronda is an independent Swiss clockwork manufacturer that has its production facilities in Switzerland and Asia. They produce high-quality quartz and mechanical movements whose designs and parameters are constantly being developed. This is one of the reasons they are used as partners by many producers around the world.

– in collaboration with a leading Swiss manufacturernA Swiss company founded in 1950 in La Chaux-de-Fonds. The company has a long tradition in the field of assembly, design and production of high-quality mechanical movements. Over the years, Sellita has become an important pillar of the Swiss watchmaking industry.nProud of its independence, Sellita takes care of all brands and treats all its clients on the same terms. Aware of the need to work for clients who are sometimes competitors, Sellita maintains the strictest confidentiality in order to best protect the interests of its various clients. Sellita is constantly committed to responding to the specific needs and expectations of each client. That is why we highly value working with such a company.

Gold is almost three times heavier than iron, with a specific weight is 19.29 g per cm3. It is used mainly for producing jewellery, often in the form of alloys. Gold content in jewellery alloys, i.e. its purity, is expressed in carats.

We use titanium in both sports models and women’s models. It is a light gray metal, color-stable and hypoallergenic. For weight comparison – titanium is approximately 32% lighter than steel. After polishing, it is almost indistinguishable from steel. Titanium is also used in the aerospace industry and in the medical sector due to its properties.

Stainless steel 316L is strong, hard and corrosion-free. It is also used in the food industry, medicine (surgical instruments) and other branches of the jewellery industry. The machining of this extremely high-quality material is difficult, and demands the use of modern high-precision CNC machines.

Damascus or Damascene steel are usually two types of steel material welded or forged into patterns. They can then be worked with, both in terms of structure, annealing and color.

AUSTENITE. Stainless steel combining two austenitic – non-hardenable steels. Both components are distinguished by their low nickel content. It is hypoallergenic, suitable for contact with human skin. Etching the damascus emphasizes an interesting pattern during its production. Polishing the damascus parts is a precise manual work that takes an experienced employee up to 6 hours.

The Rainbow-Zr composite is a combination of Titanium and Zirconium. It has high corrosion resistance and is hypoallergenic. Its properties are based on the characteristics of the individual elements – the lightness of titanium and the hardness of zirconium. The resulting material has a unique structure that is unrepeatable in other composites. The composite consists of 80 layers.

A lightweight, extremely durable and hypoallergenic material used in aviation, astronautics and modern medicine. Designed for maximum reliability even in extreme conditions, it delivers one of the most technologically advanced designs in the history of the PRIM brand.

Bronze is a living material that responds to the environment and lifestyle of its wearer. The resulting patina protects the surface while telling a story. Bronze has been and continues to be a popular and sought-after material for diving watches.

A rare, silver-colored precious metal that is prized for its corrosion resistance, high density, and luster. Given its price, platinum watches often become an investment.

This is the most commonly used glass on PRIM watches. The main advantage is the price/quality ratio. Another advantage is that this glass is easier to machine than is the case with sapphire glass. While not as hard as sapphire, it is sufficiently resistant for normal use. The properties of mineral glass have another advantage – it refracts light at a much softer angle than sapphire glass.

Many PRIM models use sapphire glass (if it is not included, we are able to make sapphire glass to order). This is synthetic sapphire, a clear corundum, which is very scratch-resistant (sapphire glass can be scratched or broken during normal wear). On the Mohs scale, the hardness of sapphire corresponds to a level of 9, which is only one level less than diamond. Today, sapphire glass is the material of choice for many types of watches. With the development of technology, it is possible to treat these glasses with anti-reflective coating. This is a method where the glass is treated with an anti-reflective coating on one or both sides.
