Common Issues with Automatic Mechanical Watches’ Accuracy
1. Type I Automatic Mechanical Watches (Men’s Watches): Acceptable daily accuracy range for top-grade watches is between -20 to +30 seconds; for first-grade, it’s -30 to +60 seconds; and for standard quality, -50 to +90 seconds. Continuous operation should exceed 36 hours.
2. Type II Automatic Mechanical Watches (Medium Watches): For premium watches, the daily variance is set between -25 to +50 seconds; first-grade watches vary by -40 to +80 seconds; and acceptable pieces fluctuate by -60 to +120 seconds, with all expected to run for over 30 hours without interruption.
3. Type III Automatic Mechanical Watches (Women’s Watches): The highest quality watches should have a daily error of -30 to +70 seconds; first-grade items, -50 to +100 seconds; and standard ones, -70 to +150 seconds, with a minimum continuous running time of 28 hours.
Note: Consistent daily deviations indicate quality craftsmanship. If adjustments are necessary, ensure to visit a professional and reputable watch repair shop. Remember, fine watches are not worn out, but improperly serviced. Always entrust your valuable timepiece to experienced technicians for tuning, to avoid unnecessary damage and to ensure precision and longevity.
