I purchased a Regal diver-style watch, but it originally had a dummy diver-style design with a fixed bezel (this is a method sometimes used that only imitates the diver style). So, I used the case from another rotating bezel watch, a Mild Seven watch. This watch had a mechanism to illuminate the back and also had a button, but I filled it with putty and painted it. Coincidentally, the movement (quartz part) was the same. I only swapped the Regal dial into the Mild Seven watch. I glued an inner bezel that fit the diameter. Therefore, I will consider this a repair part for the Regal watch. If you understand the explanation, please purchase. Small and stylish rotating bezel quartz watch. The bezel rotates, but it does not have the water resistance mechanism of a diver's watch. It is an item to quickly know the elapsed time from the zero mark on the hour hand.
