Yes, The tonneau watch's luminous maintenance time is irradiated with bright light for half an hour, allowing the luminescent material within to absorb enough light energy to allow you to see the time clearly in the dark.

Automatic mechanical watches are also known as automatic winding watches. A self-winding watch movement has a mechanism which winds the mainspring using the natural motions of the wearer's body. The watch contains an oscillating weight that turns on a pivot. When you wear it, the oscillating weight will oscillate due to your movement, thereby automatically winding. As long as you move, the watch will never stop.

There are two types of mechanical watches: manual-winding watches and self-winding watches. All of our watches are self-winding watches, also known as automatic mechanical watches. Under normal circumstances, a watch that is moving does not require additional manual winding. When the watch is not worn for a period of time, the watch will stop moving. At this time, it takes about 20 turns of manual winding. Please do not overwind the watch to avoid damage to the watch. Here is Instruction Manual.

If not worn, the automatic watch can keep ticking for about 40 hours if fully wound. After this duration, it may stop. To activate it, just wear it again and the watch is ready to go. But in this case, we recommend winding 20 turns by hand, which can make the watch build the power reserve quickly.

A Tonneau watch means a watch with a barrel-shaped case. Different from traditional round or square cases, Wishdoit Watches exclusively designs tonneau watch for men.

This is absolutely impossible. If you touch hot water, the movement inside will be damaged, and a lot of fog and condensation will be generated.

When you get the watch, you must first wind it 20 to 30 laps to keep it running and running all day. If an automatic watch is worn every day and subject to an average amount of hand motion, it will not need to also be wound manually. However, if you are preparing an automatic watch to be worn again after it has been left in storage for some time, simply shaking and setting it will not suffice. We therefore recommend that you wind the crown of your automatic wristwatch several times to support power supply before wearing it again
