ETA 955.102 Movement 2-hand

1. Basic Attributes & Dimension Specifications

• Movement Type: Quartz-controlled stepper motor movement, with an oscillation frequency of 32768Hz (the standard frequency for quartz movements, ensuring basic timekeeping accuracy).
• Dimension Parameters:
  • Diameter: 25.6mm (corresponding to 11½ lignes), compatible with men’s watches with a diameter of 38–40mm and large-sized women’s watches;
  • Thickness: 2.50mm (slim design, suitable for pairing with ultra-thin watch cases and ideal for styles pursuing a lightweight wearing experience);
  • Hand Specifications: 120/70/20 (referring to the length specifications of the hour, minute, and second hands respectively, supporting the assembly of standard-sized dials).
• Power Source: Compatible with button cells of model 371 or 395, with different batteries corresponding to different battery life periods — the 371 battery has a theoretical lifespan of 78 months (approximately 6.5 years), while the 395 battery has a theoretical lifespan of 108 months (approximately 9 years). Its battery life outperforms that of most entry-level quartz movements from the same era.
• Crown Specification: Equipped with a crown of model 401-1906, which is default compatible with the 3 o’clock crown position, conforming to the operating habits of mainstream wristwatches.

2. Core Functions & Structural Features

1. Time Display: Adopts a 2-hand, date-free design (only hour and minute hands, no second hand or date display function). The dial layout is extremely simple, visually aligning with styles that emphasize simplicity and practicality, such as vintage and military styles.
2. Jewel Bearings: Equipped with 7 synthetic ruby bearings, installed at high-friction parts like gear axles. These bearings effectively reduce component wear, extend the movement’s service life, and improve the stability of timekeeping.
3. End-of-Life (EOL) Battery Indicator: Built-in EOL display function. When the battery is nearly depleted, the hands will operate abnormally (e.g., changes in the interval of the second hand’s jumps), reminding the user to replace the battery in a timely manner and avoiding disruptions to use caused by sudden stoppages.
4. Simplified Structure: Without a date-switching mechanism or complex transmission components, the movement has a low failure rate and low maintenance costs. It is also easy to repair and maintain (this model is commonly found in the second-hand market, still operating stably after maintenance).

3. Application Scope & Representative Watches

• Military-Style Watches: Such as the CWC G10 watch — a modern reissue of the classic military watch supplied to the British Ministry of Defence. It features a 38mm case and is equipped with the ETA 955.102 movement, with core characteristics of a simple dial and high durability. Its market reference price is approximately 1,480 yuan.
• Vintage Minimalist Watches: Suitable for small-dial (36–38mm) vintage styles. Without redundant functions, it restores the “basic timekeeping” essence of mid-20th-century watches, often paired with leather straps to enhance the vintage texture.
• Entry-Level Practical Watches: Targeted at users with basic timekeeping needs (such as the elderly or daily commuters), its long battery life reduces the frequency of battery replacement, and its simple operation (only time adjustment required) lowers the threshold for use.
