Felsa 28 Watch Spare Parts: Detailed Guide for Collectors and Watchmakers

The Felsa 28 is a vintage Swiss manual wind movement celebrated for its robust engineering and nuanced construction. Featuring a direct-driven center second, 17 synthetic jewels, and operating at 18,000 vibrations per hour (vph), it was built with a unique two-layer structure and often graced with gold-toned chatons and a nickel screw balance for heightened reliability. Its 10.5 ligne size made it suitable for mid-century men’s wristwatches, and two three-legged shock protection systems were employed for extra durability.
