How do you open the back of a watch without a wrench?
In this case, simply flip the watch over, grip it in one hand by the watch strap, and hold the friction ball against the case back with your other hand. Apply some pressure and rotate the ball counter-clockwise – if the case back is loose enough, it should unscrew fairly easily.
Why do some watches have a rotating bezel?

How do you measure a watch bezel?
Slowly open the jaws until they rest snugly against the edges of the watch case from the twelve o’clock position and the six o’clock position. This will give you the inside diameter of the watch case and the diameter of the watch crystal. Repeat this measurement to ensure an accurate reading. Note down your result.
What is a ceramic bezel watch?

Base metals are often more abundant in nature and sometimes easier to mine. That makes base metals far less expensive for use in manufacturing than precious metals.
