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?
  • Inspect the underside of your current watch strap for width indicators.
  • Measure the space between your watch lugs (in millimeters) using a metric ruler.

Amazing quality

Extremely happy with my purchase, the quality is top notch.


Really Good quality it matches with my Black PVD watch. Only wish that the black buckle was the same style as the one that comes with the strap.

Beautiful strap, Excellent Customer Service

The strap arrived quickly to Canada via USPS and Canada Post and I was able to track the shipment while it was with USPS. Excellent quality leather for $60 US, in the short length I prefer. I will definitely buy Colareb again and from Holben’s. I’m wearing it on my Timex Expedition and Islander ISL-107.

Excellent Strap and Customer Service

I knew I wanted to try Colareb vintage leather straps, the price with Holben’s was as good as ordering direct from Colareb in Italy. The straps arrived quickly to Canada via USPS and Canada Post and I was able to track the shipment while it was with USPS. Excellent quality leather for $60 US, in the short length I prefer. I will definitely buy Colareb again and from Holben’s. First pic is the strap on my Long Island Watch Company 39mm Flieger ISL-107.

Great alternative

I didn’t care or the original band on my Hamilton Khaki field. This band, paired with the the black stainless buckle is a solid alternative!
