Tissot PRX Powermatic 80 40mm vs Longines Conquest 39mm Automatic

🕰️ Movement & Performance

Tissot PRX Powermatic 80

• Powered by the Powermatic 80.111, a Swiss automatic movement with an impressive 80-hour power reserve, 3Hz beat rate (21,600 bph), and a Nivachron balance spring for anti-magnetic properties.

• Accuracy generally ranges between ±3–15 seconds/day.

• Ideal for those who want longevity between wears and minimal winding.

Longines Conquest Automatic 39mm

• Equipped with the Longines L888 movement, based on the ETA A31.L01. It offers a 72-hour power reserve and runs at a 3.5Hz beat rate (25,200 bph), slightly smoother than the PRX.

• Higher beat rate improves sweep smoothness, and many users report ±5–10 seconds/day accuracy.

• Typically comes with a silicon balance spring and COSC-level consistency on some variants.

Verdict: Both offer long power reserves and Swiss quality, but the Longines L888 has a slight edge in smoothness and precision.
