You simply get one without a face.Many clocks have the hands outside the body.
To prevent your bathroom mirror from fogging up, you can use an anti-fog bathroom mirror that has a special coating or heating element to reduce condensation. This will help keep the mirror clear even in steamy conditions.
No. The steam from a hot shower fogs the mirror.
because when water is hot, it evacuates and turns into gas which fogs
It will help take away the humid fog that bathrooms gather up during showers.

Cold air holds less moisture than warm air. When you run the shower with hot water, the moisture condenses on the cold mirror surface causing it to fog up. If you run the shower cold, the mirror will not fog up.
When you take a shower the water droplets have a greater surface area then simply having the water sit in the tub as it does in a bath. The leads to increased evaporation. With more moisture in the air it is easier for condensation to occur on a cool surface such as a mirror.
Upslope fog
It is not normal for a military gas mask to fog up.
Steam fog is fog that that comes off of water. It comes up when it is really ht outside.
There are powered, heated mirrors that don't fog up at all, surprisingly!
