Clarifications
The Japanese NH35 movement is a mechanical automatic movement, not a quartz one.
It means that the watch winds itself with the motion of your wrist and does not use a battery. Manufactured by Seiko Instruments Inc. (SII), it is one of the most famous, reliable, and widely used mechanisms in independent and affordable watchmaking worldwide.
Key features

• No battery: It works thanks to an internal spring that stores energy.
• Automatic winding: An oscillating weight (rotor) rotates with every movement of your arm, winding the spring.
• Manual winding: You can also wind it by turning the crown (the side knob) by hand.
• Hacking: When you pull out the crown to set the time, the seconds hand stops. This allows for precise setting to the second.
• Frequency: It oscillates at 21,600 vibrations per hour, offering a fairly smooth sweep of the seconds hand.
• Power reserve: When fully wound, the watch continues to run for about 41 hours even if left unworn.
• Reliability: It is a true "workhorse" in watchmaking. It is shock-resistant and very easy to repair or replace at a low cost.
