The ETA 955.112 movement is a high-quality quartz movement manufactured by ETA SA, a leading manufacturer of watch movements. The 955.112 is part of ETA's quartz movement series, and is known for its reliability, precision and robustness. Here is a detailed description of the movement:
1. Movement Type
- Quartz movement: This is a quartz movement, which means it uses a quartz crystal to regulate time, as opposed to mechanical movements that rely on gears and levers.
- Compatible Case: This movement is designed to be installed in watches of a compact size, usually with a case diameter of 30 mm to 35 mm.
2. Main features
- Time display: The 955.112 is a quartz movement with two hands (hours and minutes), with a simple and clear time display.
- Central seconds: Features a central seconds indicator, which moves continuously, typical of quartz watches.
- Battery-powered case: The movement is powered by a standard battery (usually type SR626SW or equivalent), which guarantees a battery life of around 2-3 years, depending on use and environmental conditions.
3. Accuracy
- Quartz precision: Like all quartz movements, the ETA 955.112 is extremely precise, with a tolerance generally within a few seconds per month. This is one of the main advantages of quartz over mechanical movements.
4. Functions
- Date function: The ETA 955.112 movement has an output for displaying the date, which is usually positioned at 3 o'clock (but depends on the design of the watch).
- Rapid date advance: The rapid date advance function allows the date to be changed quickly by turning the crown in a specific direction, without having to go through all the dates manually.
5. Battery Life
- Battery life: As mentioned above, battery life may vary, but is usually around 2-3 years, depending on the quality of the battery used and the intensity of watch use.
6. Dimensions and Thickness
- Compact dimensions: The ETA 955.112 is designed to be compatible with small and medium-sized cases, usually between 30 mm and 35 mm in diameter. The thickness of the movement itself is relatively thin, making it ideal for smart and casual watches.
7. Reliability and Durability
- High reliability: ETA is a brand renowned for producing quality movements. The 955.112 is no exception, and is known for its durability and resistance to shocks and vibrations.
- Shock resistance: The movement is designed to withstand shocks and normal conditions of use, although, like all quartz movements, it must be treated with care to ensure optimal performance.
8. Use
- Wristwatches: The ETA 955.112 movement is mainly used in mid- to high-end wristwatches, which are characterised by quartz precision and functionality.
- Fashion and luxury sector: Many watch brands use the 955.112 in stylish and sophisticated watches, as it offers an ideal combination of performance and design.
Conclusions
The ETA 955.112 movement is a robust and precise quartz movement with a simple but functional time and date display. Its reliability and precision make it an ideal choice for quality wristwatches, and it is appreciated for its battery life and reliability over time.
