- low beat mod, this is actually a big difference and an instant tell for people that know. (if you have the v7 with a miyota 9015, then this mod is not possible) ~$200
- date wheel switch, mikey from RWI makes good stuff, it's quite easy to tell the v7 date wheel and the gen apart. ~$35 wheel + $50 service
- bezel screw mod, rounded, brushed and recessed. compare it with a picture of a gen, lots of people on this forum can tell the difference very easily, if you can't then don't worry about it. ~$60
- rebrushing of SS bezel, this mod makes it so the brushing is a bit less likely to scratch later on, not needed if you're really careful with your watch. ~$45
- gen strap/buckle, the gen rubber feel is really different honestly, but a feet or two away it's not that different visually. ~$350
- movement service, different from low-beat mod, this makes it so that there's no gunk or dirt on your movement and guarantees that it lasts longer and is more precise. ~$150
improvements but non-gen-like:
- prof 2xAR crystal ~$140
- prof 2xAR cyclops ~$130
- relume (super glow!) ~$130
