The RM10 was too big for me. The RM5 fits me like a glove. That being said, the greater transparency of the RM10 is nice. IMHO, they are equally sporty.

well, if your wrist and pocket can take it , why not?
BTW, the RM5 has more problems than other model and I suppose the RM 10 is an improved version. I have an indonesian friend who has RM 5 in all metals - titanium, wg and rg and all these got problems. I guess it is his luck - I mean BAD luck to have strike 3.
..No problems with my 10, and I have to disagree a little with you Eric, I think the RM10 on a quality band in white gold is a very nice watch to go with formal wear. Ok its not going to look as subtle & 'dressy' say a s a Patek, but it will look very fashionable me thinks. The best bit about the RM10 for me is the little ruby hammer that twinkles as it hits the wheel...anyway here are some pics to show it
go with the 10....beautiful watch



I have a WG RM 10 which runs flawlessly and looks brilliant on the new vented rubber strap (casual) and dark brown croc ("formal").
Out of the 15 or so watches I own, the RM gets the most notice and compliments.

What I think is a great watch for formal wear will be different than yours
Having said that, I think any RM would be great with a suit or tuxedo.
People still wear black plastic quartz IronMan watches with suits/tuxedos, so to each his own.
