I've Googled watch strap for 6" wrists and waded through the avalanche without much success. I'll have a look in town next time I'm there but I'm not hopeful as finding a leather or fabric strap has always been a problem for me and punching more holes never looks good. Many metal straps don't have enough removeable links or enough micro adjustment and when they do the catch mechanism can leave the watch unbalanced on the wrist and lead to it moving to one side which is annoying. I've been through years of this and the two Swiss watches I have have exactly this issue with their metal straps.
These mesh ones are the best solution for me so far as they have just about infinite adjustment and they're very comfortable. Once I've set them I've never had to adjust them during the day. I have had a NATO strap with holes which fitted lovely but it left too much unused stap sticking out. I also have an orange silicone strap with the same issue, it has more than enough holes and it fits lovely but there's way too much strap sticking out and cutting wont produce a nice result.
