this is another NOS I found recently.
it came with the original double velcro-lock strap, but i find that it is the 1st G that is uncomfortable to wear. so i changed the strap, and managed to get the salmon/white strap. it looks nice for mrs. tofu.
though this model is a tough solar, the interesting thing is the 'sleep' function must be activated manually.
here are some photos. happy weekend.
