Understanding watch movements is fundamental to appreciating the craftsmanship and technology behind timepieces. A watch movement, also known as a caliber, is the mechanism that drives the watch’s hands and powers its functions. There are primarily two types of watch movements: quartz and mechanical.
Quartz movements are powered by a battery and utilize a quartz crystal to keep time. The battery sends an electrical signal through the crystal, causing it to vibrate at a precise frequency. This vibration is then converted into a constant timekeeping signal, which drives the motor to move the watch hands. Quartz movements are known for their accuracy, low maintenance, and affordability.
Mechanical movements, on the other hand, rely on a complex series of gears and springs. These movements are divided into two categories: manual and automatic. Manual mechanical watches require regular winding by the wearer to keep the mainspring tight. Automatic mechanical watches, however, harness the energy from the wearer’s natural motion through a rotor that winds the mainspring. Mechanical movements are celebrated for their intricate engineering, craftsmanship, and the aesthetic appeal of their visible movements through transparent case backs.
History of Rotary Watches
Rotary Watches was founded in 1895 by Moise Dreyfuss in the Swiss town of La Chaux-de-Fonds. The brand quickly established itself as a producer of high-quality timepieces with elegant designs. Throughout the 20th century, Rotary became known for its innovation and style, leading to its appointment as the official watch supplier for the British Army during World War II.
The 1920s saw Rotary introducing the now-iconic winged wheel logo, symbolizing the brand’s commitment to precision and excellence. In the 1940s and 1950s, Rotary’s popularity soared, particularly in the United Kingdom, where it became a household name. The company’s ability to adapt to changing market trends while maintaining its heritage has ensured its longevity and continued relevance in the watch industry.
Types of Movements Used by Rotary
Over the years, Rotary has utilized various types of movements to cater to diverse customer preferences and technological advancements. These include quartz, automatic, and specific movements like Miyota.
Quartz Movements: Rotary’s quartz watches offer high precision and low maintenance, making them ideal for everyday wear. The affordability and reliability of quartz movements have made them a staple in Rotary’s collections.
Automatic Movements: These movements are favored for their craftsmanship and the self-winding mechanism that harnesses kinetic energy from the wearer’s movements. Rotary’s automatic watches are renowned for their durability and the intricate engineering that goes into each piece.
Miyota Movements: Rotary has also incorporated Miyota movements, produced by the Japanese company Citizen. Miyota movements are known for their robustness and reliability, offering an excellent balance between quality and cost. This collaboration has allowed Rotary to provide high-quality watches at competitive prices.
Current Movements in Rotary Watches
Today, Rotary continues to innovate and incorporate a range of movements in its watches. The company collaborates with renowned movement manufacturers to ensure the highest standards of quality and performance.
Quartz Movements: Modern Rotary quartz watches continue to deliver exceptional accuracy and require minimal maintenance. These watches often feature additional functionalities like chronographs and multi-function sub-dials.
Automatic Movements: Rotary’s automatic watches are equipped with both Swiss and Japanese automatic movements, ensuring a blend of heritage and reliability. These movements are meticulously tested to meet Rotary’s stringent quality standards.
Proprietary Technology: Rotary has developed some proprietary technologies and movements, particularly in its flagship models. These innovations often include enhanced power reserves, improved accuracy, and refined aesthetics.
Advantages of Each Movement Type
Each type of movement used by Rotary offers distinct advantages, catering to different preferences and needs.
Quartz Movements: The primary advantage of quartz movements is their accuracy. Quartz watches typically gain or lose only a few seconds per month, compared to mechanical watches that can deviate by several seconds per day. They are also more affordable and require less maintenance, with battery replacements needed only every few years.
Automatic Movements: Automatic movements are prized for their craftsmanship and the absence of a battery, which means they can last indefinitely with proper care. The self-winding feature adds convenience for those who wear their watches regularly. Additionally, the visible movement through the case back offers a captivating glimpse into the watch’s inner workings.

Miyota Movements: Miyota movements are known for their reliability and durability. They offer a good balance between precision and cost, making them an excellent choice for those seeking quality without a high price tag. These movements also have a strong reputation for robustness, often withstanding shocks and impacts better than more delicate Swiss movements.
How to Identify the Movement in a Rotary Watch
Identifying the movement in a Rotary watch can be done by examining several aspects of the watch:
Case Back: Many Rotary watches have transparent case backs that allow you to see the movement. Automatic movements typically feature a rotor that moves with the motion of the watch, which is easily visible through the case back.
Markings and Engravings: The case back or dial may have markings indicating the type of movement. Terms like “Automatic,” “Quartz,” or specific movement numbers can provide clues.
Documentation: The watch’s manual or warranty card often details the type of movement used. This information can also be found on Rotary’s official website or by contacting customer service.
Watch Model: Researching the specific model number online can provide information about the movement type. Many watch enthusiasts and retailers provide detailed descriptions and reviews that include movement details.
Maintenance and Care for Rotary Movements
Proper maintenance and care are essential to ensure the longevity and performance of your Rotary watch.
Quartz Watches: These watches require minimal maintenance. Regular battery replacements every 2-3 years and occasional servicing to check the seals and gaskets are usually sufficient. Keep the watch away from extreme temperatures and strong magnetic fields to avoid affecting the movement.
Automatic Watches: These watches benefit from regular wear to keep the movement running smoothly. If not worn daily, consider using a watch winder to maintain the power reserve. Automatic watches should be serviced every 3-5 years to clean and lubricate the movement and check the water resistance.
General Tips: Avoid exposing your watch to shocks and impacts, as these can damage the movement. Store your watch in a cool, dry place when not in use, and consider using a watch box or pouch for added protection.
Comparison Rotary Movements with Other Brands
Rotary’s watch movements compare favorably with those of other brands in similar price ranges and categories. In the mid-range market, Rotary’s use of reliable quartz and automatic movements from reputable manufacturers like Miyota places it alongside brands such as Seiko, Citizen, and Tissot.
Seiko: Known for its robust in-house movements, Seiko offers a range of quartz and automatic watches. Rotary’s use of Miyota movements provides a similar level of reliability and precision.
Citizen: Like Rotary, Citizen uses Miyota movements in many of its watches, ensuring durability and accuracy. Rotary’s design aesthetics often focus on classic and elegant styles, providing a distinct alternative to Citizen’s more diverse offerings.
Tissot: Tissot, part of the Swatch Group, is renowned for its Swiss-made movements. Rotary’s automatic watches with Swiss movements can compete with Tissot in terms of craftsmanship and performance, often at a more accessible price point.
