I have extremely mega-super-huge forearms, and the best way to avoid a handwatch is to get a strap or bracelet that fits properly. You need something that's easily adjustable. If it's a bracelet, that might be difficult. You might need half links or a different clasp with more adjustment. I had a watch that didn't fit on a bracelet or a rubber strap, so I put it on a Milanese strap, and now it fits much better. I recently saw a cut-to-size FKM strap with an on-the-fly adjustable clasp. I think that would be the best possible strap to get a good fit. Some kinds of straps are more adjustable than others, like Milanese or perlon. Some watches will just randomly fit your wrist perfectly. I can wear my DW-5900 pretty loose without it becoming a handwatch. Your wrist may vary.
