Q: Do you sell watch bands for women?
A: We do! Many of our short-length straps are the perfect size for women.

Q: Can you suggest a strap that looks amazing with my watch?
A: Unfortunately, because the range is so vast (and personal taste is subjective), we cannot advise regarding aesthetic suitability for specific models and styles of watches.

Q: I have an Apple watch. Will any of your straps work for me?
A: Sure! Our handy Apple watch band adapters accommodate most 22mm straps.

Q: Are spring bars available?
A: Yes, for each strap that is not already integrated with quick-release spring bars, we include one free pair of strong, seamless double-flange stainless steel bars.

Q: What strap size do I need?
A: To determine your size, use a metric ruler to measure the internal distance (in millimeters) between the lugs of your watch.

Q: My Bonetto Cinturini deployant strap is too long. Can you help?
A: Of course! See our Bonetto Cinturini sizing guide for cutting instructions.

Q: Do you offer international shipping?
A: Yes! Visit our Shipping & Returns page for more information.

Q: May I return my purchase?
A: Holben's Fine Watch Bands accepts returns of unworn, undamaged merchandise for refund or exchange within thirty days of purchase. Learn more on our Shipping & Returns page.

Need help with sizing?

My Favorite Band

This thin, light weight, flexible band with a nice amount of stretch is my go to pick for multiple watches.
I removed the extra pass of rubber and the extra metal keepers to create the most comfortable single pass strap I own.
This strap is very long apparently to allow wearing over a wet suit, but it cuts down very easily with a razor blade, knife , or sharp scissors to allow a custom length of tail after the keeper.
A plastic water bottle lid or coin made a nice guide for cutting the end to perfect length.
Ordering more for sure!

Good Quality Band

This was a great purchase. Was looking for an alternative to my factory Tudor rubber FXD rubber band. This easily converted to a single pass band by removing two spring pins and the secondary strap. Not as thick as the factory strap but cleaner and smoother. Good value.

Just found my Favorite NATO

I Just found my Favorite NATO and its Rubber from Bonetto Cinturin! Fit is perfect and its very comfortable. Perfect all around strap.

Great Rubber Strap!

The best rubber strap I have. It's comfortable and strong for being thin. Will buy another one. Holben's is where it's at!

Gary Trevisan
Best NATO I own!

This is the perfect NATO for my use. I wanted a strap that was lite, that was rubber, that smelled great, and looked good. Plus you easily make it a single pass ZULU. I wish they had it in Orange.
