The ETA 1315 is a vintage automatic mechanical watch movement from the Swiss ETA 1300 family, renowned for its reliability in mid-20th-century timepieces. Produced primarily in the 1950s and 1960s, it features a 9.25 ligne diameter and serves as a robust base for various dress and sports watches. Its design emphasizes precision engineering with a central sweep seconds hand and bidirectional rotor winding.
Key Specifications
Size and Type: 9.25”’ (20.8mm diameter), automatic self-winding with hackable seconds in later variants.
Jewels: Typically 17 or 25 jewels, reducing friction for longevity.
Frequency: 18,000 vph (2.5 Hz), balancing power efficiency and smoothness.
Power Reserve: Approximately 40-50 hours, powered by a single barrel.
Design Highlights
The ETA 1315 belongs to the ETA 1300 series, evolving from manual-wind models like the 1301 to include automatic functionality via a peripheral rotor. It shares DNA with siblings such as the 1316 (date) and 1317 (day-date), often used by brands like Omega and Longines for affordable yet durable calibers. Adjustments for temperature and positions ensure chronometer-grade potential in regulated examples.
