PRECIDRIVE
PreciDrive technology redefines typical accuracy standards to +/- 10 seconds per year. The quartz crystal and integrated circuit (IC) are now enclosed in a ceramic case that protects them from moisture. The principle of thermal compensation controls and regulates the motor pulses according to changes in ambient temperature, meaning that PreciDrive meets the strict requirements for COSC (Contrôle Officiel Suisse des Chronomètres) chronometer certification. All this provided that the watch is not subjected to shocks and is stored at a temperature between 20°C and 30°C.
This is a unique achievement that brings real added value to the watch.

HEAVYDRIVE
The exclusive HeavyDrive integrated circuit provides an anti-shock system and expands the possibilities of balancing the hand movement. The weight of the innovative design or hand material is no longer an obstacle, as HeavyDrive can handle imbalances of over 200% for a traditional second hand and 20% for a traditional minute hand. The movement’s built-in electronics detect and then manage the shock, while the motor generates a counter-pulse that locks the hand in position during the shock. This intelligent shock management prompts the motor to react in a fraction of a second if a certain shock threshold is exceeded. The energy used to suppress this force remains minimal, thus preserving the movement’s autonomy.

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 watchmaking “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. A chronograph is usually controlled by two crowns. Chronographs can be powered by either quartz or mechanical movement with manual or automatic winding. Mechanical chronographs are generally taller than simple watches because the complicated movement takes up more space in the watch case. We offer mechanical chronographs in limited PRIM series every year.

– in collaboration with a Swiss manufacturer
Collaborating with a company that manufactures watches for companies like the Fossil group has opened up huge opportunities for us. We offer you the originality and quality that you can find in world brands and now also in PRIM watches. In 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 have been 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 manufacture that produces high-quality mechanical movements bearing the “Swiss made” label. The company’s motto is “we combine quality, advanced technology and mechanics with Swiss craftsmanship.”

In 1881, he founded the Kintaró Hattori company. Seiko is one of the few fully integrated watch manufacturers that designs and develops its own calibers using cutting-edge technology. Under the Seiko brand, innovative solutions in electronic watches were introduced, in 1969 it was the first quartz watch, later the company introduced the first quartz chronograph, and in 1969 the automatic chronograph “Seiko caliber 6139”.

The group was founded in 1955 and holds the title of the largest mechanical movement manufacturer in the world. Tradition of production, experience in watchmaking, strong technical background and technical development of CNC machines that custom-make all components – that’s what Sea-Gull is. Seagull was awarded the A-value measurement class, received a complete certificate of quality and reliability testing ISO 9001.2000.

Ronda is an independent Swiss watchmaking manufacturer with production facilities in Switzerland and Asia. They produce high-quality quartz and mechanical movements that are constantly being developed. This is one of the reasons why they are used in the market as partners for many global brands like us.

– in cooperation with a leading Swiss manufacturer. 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 watch industry. Proud of its independence, Sellita takes care of all brands and treats all its clients on equal terms.

In terms of properties, gold is almost three times heavier than iron, its specific gravity is 19.29 grams per cubic centimeter. It is mainly used for the production of jewelry, in the form of alloys. The gold content in jewelry alloys, or fineness, is expressed in carats.

We use titanium in both sports models and women’s models. It is a light, gray metal, color-stable and anti-allergic. 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.

The 316L stainless steel used is strong, hard and corrosion-resistant. It is also used in the food industry, the medical industry – surgical instruments, and also in other branches of the jewelry industry. It is a very high-quality material that requires machining, which is carried out on modern CNC machines with high precision.

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 Damascus 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 damask emphasizes an interesting pattern during its production. Polishing damask parts is a precise manual job that takes an experienced employee up to 6 hours.

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.

Lightweight, extremely durable and hypoallergenic material used in aviation, astronautics and modern medicine. It is designed for maximum reliability even in extreme conditions and brings 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 and tells a story at the same time. Bronze has been and still is a popular and sought-after material for diving watches.

A rare, silver-colored precious metal that is valued primarily for its corrosion resistance, high density, and luster. Considering the price, platinum watches often become an investment item.

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. It is a method where glass is treated with an anti-reflective coating on one or both sides.
