my wrist is 17cm..so that's 6.5" or so...
i've got a couple of friends with a rep and gen SS diver, i got to try them on and they do feel solid on the wrist and has a lot of presence. I chose the FC because all my other reps are SS, felt like getting something new and I love the steath look of it. But whichever you choose, they're both stunning.
here's a wrist shot:
it's a tad loose on the last hole of the rep strap, still wearable but I like wearing my watches just nice with very minimal movement. I didn't feel like getting a gen xs strap as well.
I did search around and i found the ap diver strap hole is 2x7mm, so I made an extra hole by drilling 3x 2mm holes and cleaning up the leftover bits with wire cutters
here it is after drilling (note the leftover bits in the hole)
and here it is completed
happy to have saved 299 usd on a gen strap
