What I found in a quick search: There seem to be (at least) 2 variants. One with Titanium case (hence the Titanium in the name).soem nice pics here:http://forums.watchuseek.com/f78/wenger-standard-titanium-issue-mid-size-095-0695-a-613737.htmlThe version you pictured seems to have a (nickel?) plated base metal case, as you can see scratches and scuffed areas on the pic of the backside. And usually the caseback reads "All stainless" when the case is ss.It is a Quartz watch (battery powered) for sure. The size (around 38 mm measured across the case from 9-3 hrs, without the crown) is medium sized, a nice men´s dresswatch unlsee you have huge arms, IMHO. I don´t loke watches over 42mm (Seiko or citizen divers)The G-Shock will wear bigger as it is much thicker, but the dial size will be comparable, if not a tad bigger on the Wenger.If you find a nice example, take it. Keep in mind tah tit has somewhat strange 19 mm lugs, but most 20mm straps will fit.
