Sapphire crystal is extremely hard, second only to diamond. This hardness makes it highly resistant to scratches, ensuring the watch face remains clear and legible over time. It is also very durable and resistant to shattering or cracking under normal wear and tear conditions.

The NH34 movement includes features such as hacking (the second hand stops when the crown is pulled out) and hand-winding, providing convenience for setting the time and manually winding the watch. Its power reserve lasts for 41 hours, ensuring stable operation for a long time.

BGW9 provides excellent brightness and visibility in low-light conditions, making it easy to read the time even in darkness or low-light environments. It can last for at least 5 hours in dark and is able to quickly absorb and store light energy in a bright environment.

This watch is tested for water resistance to 100 meters, but can provide water resistance up to 200 meters. It can be worn in daily life, and can also be used for swimming and diving. The caseback is sealed and the crown is spiral, which increases its waterproof performance.
