I don’t anything about them am starting a low bid as I have no idea of their worth but none of them look great - there are varying degrees of scratches/wear and poor straps.  

The only one currently working is the Envoy one - the glass face is scratched and the blue and red material strap would need replacing 

The Sekonda one comes with its original case and guarantee (which has run out now) 

Please be aware that these are not in great condition, I would just be happy for someone to make some use out of them rather than them sitting in a drawer.
