I have a few G-Shocks but after purchasing a Cartier Tank and wearing it for while, I have found that I am started to gravitate towards smaller discreet watches. Now when I put on my G Shocks or Omega Hour Vision, they feel enormous. So I pulled the trigger on an F91W and I really like the size on my 8" wrist. The only problem is that the band is too small. I have to put the clasp through the second last hole, which is fine but then the keeper keeps shifting and the band end pops out. It might do the 30 times a day which is annoying. I thought about getting some Loctite 401 and glueing the keeper in position but then I would not be able to get the strap in and out easily. So I now look to the A158W but I am wondering if I wouldn't have the same issue. I am unable to try one in the flesh and so I am wondering if anyone has both of these watches and is able to tell me if the metal band fits a larger wrist than the F91W? Thanks.
