If the luminous light of the watch cannot be displayed or is not obvious in the dark night, it may be because the watch does not absorb enough light during the day, which leads to the lack of light that can be released at night. It is recommended to receive light for a period of time during the day, and it will be more obvious at night when it presents a luminous light. If the watch still has no luminescence or the luminescence is not obvious after irradiating with light, it is recommended to contact Lucky Harvey for watch warranty service maintenance.

To activate the watch luminous effect, you can put the watch under stronger sunlight or light for a period of time, let it replenish energy through irradiation to automatically glow at night. The intensity of the luminous effect may vary depending on usage habits and environmental factors, so please refer to actual usage.

Sapphire mirror has anti-wear and anti-corrosion qualities, although the hardness of the sapphire mirror is very strong, second only to diamonds and 7 times the hardness of steel, but it does not mean that it will not wear. Try not to touch diamonds, granite, concrete, grinding stones, sandpaper, nail files, etc., so as not to scratch the sapphire mirror of the watch.

In general, a waterproof watch does not mean that water vapor will never enter it. If you take a bath with the watch, the waterproof rubber ring used for the watch will be eroded by detergents and other chemicals to accelerate the aging, and the waterproof function will be invalidated. Such as in the sauna, air-conditioned rooms, etc., if the humidity in the air is relatively high and the temperature difference varies greatly, will cause water vapor into the watch. Rubber ring with the use of time gradually aging, waterproof performance gradually recede, once found in the watch water vapor should be timely sent to Lucky Harvey authorized repair station to deal with, so as not to cause parts rust, shorten the service life of the watch. Even if the watch has waterproof function, not all water can be prevented. Be careful when wearing a watch and don't let cosmetics containing chemicals, such as seawater, salt water bath, perfume, shampoo, nail polish, nail polish remover, etc., touch the watch. Because they will cause some corrosion to the gold plating and metal surface of the watch, contact should be avoided.

In our daily life, the waterproof standard of 30 meters only for water splash, and you can wash your hands and face while wearing; 50 meters, you can use a small amount of cold water to rinse, can not be immersed; 100 meters, can be used in the swimming pool or the surface of the sea water; any waterproof watch should not be worn in a hot bath, sauna, or in an environment with great temperature changes.

The waterproofness of a watch relies on the waterproof rubber ring on the crystal, back cover, handle, etc. The waterproof watch of 30 meters (3 ATM, i.e., 3 atmospheres) can be used for daily grooming or use in the rain, i.e., water droplets are only splashed on the surface without any water pressure being added to the watch; the waterproof watch of 50 meters can be applied to swimming and general household chores; the waterproof watch of more than 100 meters can be used for underwater work, such as swimming and snorkeling.

The automaton structure visualizes its effect with the passage of time. Lucky Harvey has developed its own power module, which has several specially shaped gears inside the watch and follower mechanical parts, forming a sophisticated and complex structure. After winding the clockwork, the mainspring of the mechanical movement provides power, and the follower mechanical parts will drive the cam and connecting rods which connect the automaton device due to the rotation of the gear, resulting in a automaton effect.

Lucky Harvey watches are automatic mechanical watches with a storage capacity of approximately 40 hours. A fully wound watch can be automatically wound by arm swinging for more than 8-10 hours per day under normal conditions, and can satisfy normal timekeeping at night when the watch is resting. If you have less arm swing in your daily activities, the power provided is not enough, you still need to wind the watch manually. Winding is clockwise 30-40 turns (no need to pull out the crown and rotate it upward). Counterclockwise is to adjust the time (need to pull out the crown and rotate it downward). The error under full winding is -15 seconds to +30 seconds in 24 hours, it is recommended to calibrate the time manually in 5-7 days, and wind the watch once for 30-40 turns at regular intervals to assist in increasing the energy of the movement, reducing the error and stabilizing the movement.

Lucky Harvey offers free repairs during the warranty period without the need to replace the original part. If the warranty period has expired, you can send the watch back for a paid repair by contacting Lucky Harvey.

The problem of watch magnetization should be dealt with as early as possible, otherwise it may lead to more serious failure of the watch. If the watch is magnetized, it is only necessary to go to the authorized maintenance point to demagnetize it with special equipment, which has no effect on the performance of the watch. In addition, when using the watch on a daily basis, you should avoid placing the watch close to places with strong electromagnetic fields, such as TVs and computers, in order to reduce the possibility of magnetization of the watch.
