While we're at it, let's take a quick look at some of the mechanical parts.

First, the rigid (probably ABS) injection molded base plate for the electronics.

The plastic strap lock has a brushed aluminum plate crimped to it with the Garmin logo embossed. Nice touch!

A close look at the strap holder reveals part lines on the inside and outside - probably a multi pull mold. (really hard to see here - sorry).
