📸 Product Gallery      🔧 How does the automatic movement work?The NH34 automatic movement winds itself through your wrist motion. Wear for at least 8 hours daily for optimal performance. You can also manually wind by rotating the crown clockwise 15-20 times when the watch is stationary. 💧 Can I swim with this watch?Yes! With 100m (10 Bar) water resistance and screw-down crown, this watch is suitable for swimming and recreational water activities. Avoid operating the crown underwater. 🌙 How long does the luminous glow last?The BGW-X1 luminous material provides bright blue visibility for several hours after exposure to light. Charge under bright light for 10-15 minutes for maximum luminosity. 📅 When should I avoid adjusting the date?Do not adjust the date between 8 PM and 4 AM, as the date mechanism is actively changing during this period. Adjusting during this time may damage the movement. 🧲 Should I keep it away from magnets?Yes, keep the watch away from strong magnetic fields (speakers, phones, computers) to maintain accuracy. Mechanical movements can be affected by magnetism. |
