The ETA Caliber 1311 is a ubiquitous presence in the world of affordable and mid-range watches. This robust and reliable automatic movement has powered countless timepieces, earning its reputation for durability and consistent performance. This in-depth exploration will delve into the specifics of the ETA 1311, examining its features, strengths, weaknesses, and place within the broader landscape of Swiss watch movements.
Understanding the ETA Caliber 1311: Key Features and Specifications
The ETA Caliber 1311 is a classic example of a workhorse movement. Its design prioritizes reliability and affordability, making it a popular choice for numerous watch brands. Key features include:
- Automatic Winding: The movement utilizes an automatic rotor to wind the mainspring, eliminating the need for manual winding. This convenient feature ensures the watch remains powered through normal wear.
- 25 Jewels: The 25 jewels contribute to the movement's smoothness and longevity by reducing friction at critical points.
- Frequency of 28,800 bph (beats per hour): This relatively high frequency contributes to improved timekeeping accuracy.
- Power Reserve: While the exact power reserve can vary slightly depending on the specific implementation, it generally offers a power reserve of approximately 38 hours. This means the watch will continue running for about a day and a half after being fully wound.
- Date Function: The ETA 1311 typically includes a date complication, displayed in a window at the 3 o'clock position. This is a highly practical and popular feature for everyday wear.
- Incabloc Shock Protection: This system helps protect the balance staff from shocks and impacts, enhancing the movement's resilience.
