Mechanical watch movements are intricate micro-machines built to exacting standards. To ensure that your
watch operates with perfect precision for many years to come, please familiarize yourself with the following:
Accuracy: The average accuracy tolerance for the NH35 movement is around -20/+40 seconds per day under
normal operating conditions. Accuracy depends very much on the natural motion of your arm.
Service Intervals: As with most precision machines, an automatic watch must be serviced regularly to maintain
peak performance. We recommend that you have your watch professionally serviced every 5 to 6 years. A
shorter service interval may be required depending on the climate and conditions the watch is exposed to.
