Probably one of the best features for the price watches out there: Full forged-carbon case & dial around a steel core, Powermatic 80 (80-hour) with silicon hairspring, and 100 m WR—all at \~75 g on wrist. It’s roughly half the weight of a steel PRX Powermatic on bracelet (≈140 g) but keeps the PRX silhouette. **Video here**: [https://imgur.com/a/bagZIjC#VkvDQec](https://imgur.com/a/bagZIjC#VkvDQec) **Condition**: Gently worn; no marks.

Powermatic 80 automatic, silicon (silicium) hairspring; date. Ref T137.907.97.201.00. **Quick Facts**: \- Forged Carbon means comfier: \~75 g vs \~140 g for steel PRX Powermatic on bracelet → about 45–50% lighter; even lighter than a steel quartz PRX on rubber (\~86 g). You notice it immediately. \- Silicon hairspring = stability: Better anti-magnetism and temperature stability than traditional alloys → steadier timekeeping in everyday life (laptops, phones, office magnets). \- Powermatic 80 = “weekend-proof”: Up to 80 hours of reserve—set it down Friday, it’s still running Monday. **Price / payment / shipping**: **$780** shipped CONUS. **PayPal F&F or Zelle**.
