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?

Waterproof, a Summer Winner!

I have already reviewed this Di Modell band in another color but I purchased a couple more because of the versatility that allows you to wear this band in summer… Sweat, or getting it wet has no affect… If you prefer a leather band but are hesitant to wear it in summer look no further…. I put this one on a Seiko Chrono and to me, it looks great…! One more thing, don’t hesitate to buy your watch bands here at Holben’s because I can attest to the quality and service you will get here… Mike will take care of you and ships his items like “greased lightning”…! 5 ⭐️’s

Excellent waterproof leather strap

I've purchased probably a dozen of this strap model in brown and black from Mike at holbens. Love it on my pilot style watches.


This Di-Modell jumbo is just another terrific watch band from Holben’s… Love it…! A band that is over 5MM + at the lugs but tapers down to around 2.5 at the buckle… Beautiful sturdy and thick band and put it on Squale because this band is actually made of water resistant leather… I didn’t buy it to dive in but nice to know that if it gets wet or you sweat with it on it’s really not going to have much of an effect… Others have said you can shower and swim with it no problem…! Don’t plan on that but good to know… Love the calf leather and the mid tan color that compliments the orange minute hand on the Squale… Has a nice buckle too, not fancy but has the DM logo on it and it’s solid… One more thing, I have purchased many watch bands from Holben’s and you will NOT find a better place, not only for selection but the delivery and service is unparalleled… AND as usual, this band was sent like “greased lightning”…! 5 STAR⭐️‘S PLUS

the jumbo

The strap works wonders for the watch - a substantial look with thick strap, matt black finish, proud white stitching. I also much like buying from a company of real people.

Definite upgrade. Warm color.

I am in love with this strap. It's water resistant and top grain leather. Stitching is beautiful. I have another one on a Hamilton.
