FAQ

Q: Do you sell 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?

Rugged and Beautiful Leather Strap

I was looking for a new strap to replace the one that came with my Citizen Promaster Dive watch and cannot be any happier with the Isofrane in anthracite that I chose. It is a high quality rubber strap that perfectly complements the watch. A very rugged look that matches the tool watch aesthetics of the watch, while also being high quality. I’m sure this strap, like the watch, will serve me well for many years. Purchase from Holben’s was fast and easy. Despite being shipped across the country, I received the strap quickly. First time customer, but it won’t be my last purchase!
