Accuracy expectations for mechanical watches

Mechanical watches are precision instruments, but unlike quartz watches, they are not designed to maintain perfect timekeeping under all conditions.

The accuracy of a mechanical movement can be influenced by many factors, including:

• Wearing habits
• Power reserve level
• Position during storage
• Temperature
• Magnetic fields
• Shocks and vibrations
• Movement architecture

For this reason, small daily variations are normal and should not be considered a defect.

Each movement is regulated according to its own technical characteristics and expected performance. Typical factory tolerances are:

• Venezianico V5000: approximately ±3 seconds per day
• Soprod M100 and derivatives: -4 to +6 seconds per day
• Sellita SW200: -12 to +30 seconds per day
• Miyota 9015 and derivatives: -10 to +30 seconds per day
• Seiko NH35 and derivatives: -20 to +40 seconds per day
• Seiko NE88 and derivatives: -15 to +25 seconds per day

Please note that these values represent factory specifications measured under controlled conditions. Actual performance on the wrist may vary depending on individual wearing habits and environmental conditions.

All Venezianico movements are regulated in multiple positions to promote stable and reliable performance in daily use.

If your watch begins exhibiting a sudden or significant change in accuracy compared to its normal behavior, our support team will be happy to assist with further evaluation.
