I think it does. I have had the watch face display on and cleaned the smudges with my shirt and the glances and notifications were swiping as if it was my finger.
 
and if so, do both sapphire or ion work?

Are you wearing gloves for cold? If so be aware of the operating specs. Using the watch below 32 degrees farenheit will void your warranty.

Operating temperature Apple Watch is designed to work best in ambient temperatures between 32° and 95° F (0° and 35° C) and be stored in temperatures between -4° and 113° F (-20° and 45° C). Apple Watch can be damaged and battery life shortened if stored or operated outside of these temperature ranges. Avoid exposing Apple Watch to dramatic changes in temperature or humidity. If the interior temperature of Apple Watch exceeds normal operating temperatures (for example, in a hot car or in direct sunlight for extended periods of time), you may experience the following as it attempts to regulate its temperature:
• Charging may slow or stop.
• The display may dim.
• A temperature warning screen may appear.
• Some data transfer may be paused or delayed.
• Some apps may close.
Important: You may not be able to use Apple Watch while the temperature warning screen is displayed. If Apple Watch can’t regulate its internal temperature, it goes into Power Reserve or a deep sleep mode until it cools. Move Apple Watch to a cooler location out of direct sunlight and wait a few minutes before trying to use Apple Watch again. For more information, see support.apple.com/kb/HT6621.
Magnets Keep key cards and credit cards away from Apple Watch, the bands, the Apple Watch Magnetic Charging Cable, and the Apple Watch Magnetic Charging Case.
 
I wore a pair of light running gloves the other morning and was surprised that it worked, even though my iPhone didn't. Didn't try any thicker ones but I'm doubtful. Of course Fore Touch will work no matter what.:D

It won't void your warranty. Why would you even think this would void your warranty?!?
 
Mine does not work with gloves. I can force touch, but swiping and selecting does nothing. My nose works great though.

Maybe the thickness of the material is a factor?

Because you are operating it outside Apple's recommended specs. Warranties only cover proper use within the specified operating parameters.
