Can be a variation of approx. 30 seconds/day - very reasonable for a vintage mechanical watch. Note: Shade of gold is bit different or seems to me different in case and braclelet, but both are Zenith and originally made like this.
This watch combines elegant vintage aesthetics with the craftsmanship Zenith is known for. Perfect for collectors looking for a unique, well-maintained piece. Feel free to reach out with any questions.
