Almost perfect

This is smooth, nicely finished quality rubber. Tasteful lines, the style and the grey color look great with the Hamilton Khaki Field Mechanical. One minor thing: the strap would be more flexible/comfortable if it did not get thicker towards the lugs, hence the 4 star rating.

As always, fantastic service from Holben's. They are my go to for straps, I don't even bother looking elsewhere.

Bonetto rubber

Great rubber strap for any watch. Nice quality smelling like vanilla. Highly recommend these straps.

All day, every day!

Awesome strap, I wear it every day with my Seiko SPB143. Had a hard time putting the fat seiko spring bars in. Really like the scent of the strap.

BEST rubber straps on the market!!

The straps are really well made for its pricepoint, very supple and comfortable on the wrist. The vanilla scent smell is strong but pleasing.

I highly recommend these for anyone looking to spice up their watches.

Very soft and great smell

For a 4.75mm strap it is VERY soft, pretty much all other rubber or silicone leave me with a red mark on my skin but this one does not. It’s very comfortable, I hope the smell doesn’t wear off soon, and I’m definitely going to order a black one.
