Designed for precision and durability, NavyStar watches became a favorite among professionals and adventurers, offering superior performance in demanding environments.

The Cyma Caliber R.458 is a vintage Swiss-made manual-winding movement, renowned for its precision and reliability. Manufactured by Cyma in collaboration with Tavannes Watch Co., this movement features a diameter of 10.5 lignes (approximately 23.3mm) and is equipped with 17 jewels to reduce friction and wear. Operating at a frequency of 18,000 vibrations per hour (vph), the R.458 ensures accurate timekeeping and boasts a power reserve of approximately 36 hours.

The R.458 supports central hours and minutes, with a running small seconds sub-dial positioned at 6 o'clock. The ratchet wheel of this movement is often marked with "Tavannes Watch Co.," reflecting the close association between Cyma and Tavannes during the mid-20th century.
