PRW-3000. I ordered some G-Shock adapters from shape ways (1624) and put them on the protrek. I thought I would share how it looks. I don't like that the watch can slide on the strap. Previously I tried it with a Zulu but the additional strap underneath made the watch sit too high because the additional strap was too short. Does anyone make a Zulu with a longer strap (the short section)?
