I am a huge Boldr fan. The Odyssey line has a bunch of different sizes and even just added a true traveler GMT. The Venture line is awesome too. Excellent support as well.

I too have a 8.25" wrist.

https://cnswatchbands.com/ Natos work great. I really dig the cotton ones

https://www.haveston.com/ Single pass leather and nylon fit very nicely

https://www.mancaveleather.com/ I will second them, on the costly side, but they are very very nice and worth it

https://www.rsmwatchstrap.com/ The vintage mil two peice fit great

https://www.bartonwatchbands.com/ The long racing strap is a winner

https://www.xeric.com/ The ribbed leather with the depolyant clasp fit really well, a little costly but look great. I can wear the ones the come with a just the simple buckle but only on the second hole

I haven yet to get them, but the https://www.martuleather.com/ straps look promising. I can let you know when my order arrives. (EDIT: Took a bit of time, but these are awesome and a great fit)

Mine is coming tomorrow! I cannot wait #38
