If you look at the picture closely you will notice the band adapters and the Nato strap he used as a band. The watch looks like a limited edition G-Lide. I miss these details first time around. Hope this helps out more.
I though maybe a g lide extreme
Ive checked every glide model made i found a listing.
There is a white one with matching strap. If he dyed these it would match dead on.
Its the tan /sand color that throws me...and makes me want this watch. Lol
I know there are military sand
G's now. BTW nice collection you have ! Thx Doug
