Usually, the watch face will tell you what the surface covering the face is made of, like quartz. It's commonly used in watches as that clear cover that protects the face. Other than that, the metals vary on the wristband and surrounding the face. Some expensive watches also use quartz or another crystal type on the inside to keep the hands of the watch accurate.
Of course, this is from what I know, so do some research for yourself before you base anything off of my knowledge.
Yes, a rock can be made of a single mineral. For example, a rock composed entirely of the mineral quartz is called quartzite. Rocks consisting of only one mineral are known as monomineralic rocks.
Fluorite is a mineral, not a rock. It is a commonly occurring mineral that is composed of calcium and fluorine. Rocks are made up of one or more minerals.
Fundamentally it is a mineral, however it is possible to get a rock type made entirely of quartz, in which case the rock would be called a Quartzite.
Jade is a mineral composed of two different minerals, jadeite and nephrite. It is not considered a rock because it is not made up of a combination of different minerals like rocks are.
A diamond is a mineral, not a rock. It is composed of carbon atoms arranged in a crystal lattice structure, which makes it a mineral. Rocks, on the other hand, are made up of one or more minerals.
the mineral is clay and there is no rock
A paperclip is neither a rock nor a mineral. It is a man-made object typically made from metal, such as steel or aluminum, and does not fit the criteria to be classified as either a rock or a mineral.

Yes, a rock can be made of a single mineral. For example, a rock composed entirely of the mineral quartz is called quartzite. Rocks consisting of only one mineral are known as monomineralic rocks.
A rock is composed of multiple minerals, while minerals are made up of one substance, like copper.
Fluorite is a mineral, not a rock. It is a commonly occurring mineral that is composed of calcium and fluorine. Rocks are made up of one or more minerals.
The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.
A rock such as quartzite or marble consists of basically one mineral. So yes, a rock could consist of a single mineral, although most definitions describe a rock as consisting of combinations of minerals.
