What material is used on the back
My skin has an allergic reaction to many forms of stainless steel, possibly nickel in SS. What material is used on the back of your GPS watches like this one?
for the garmin forerunner 10 it is mostly plastic on the back, but there are 4 screws at each corner and four small metal circles about 2mm for its contact connection plate via usb to a computer to down/upload information. These metal parts might be made of stainless steel, not sure, but is a very small component of the backing.
