Artem RM-Style Deployant Clasp Black DLC

Earn up to 365 Holben’s Rewards points on this purchase

Improve your watch strap game with Artem's popular RM-style deployant clasp. Inspired by the original Richard Mille design, this solid 316L stainless steel clasp boasts a premium black DLC (diamond-like carbon) finish. Its subtle curvature ensures conformity on the wrist, while the leaf spring mechanism guarantees a secure fit. Bonus: deployant clasps reduce wear on straps compared to a standard tang buckle.


  • Solid 316L stainless steel.


  • Available in 18mm and 20mm sizes for a perfect fit.
  • 18mm fits Artem's 19mm, 20mm, 21mm Classic and HydroFlex straps.
  • 20mm fits the 22mm and 23mm Classic and 22mm HydroFlex.
  • Section that fits into tang area of strap is 3mm wide.


  • Requires screwdriver for installation.
  • Want to pair this clasp with something else? Be sure to measure the strap at the buckle end, not the lug end!

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.

Well made and easy to install

Purchased the Artem RM style deployment clasp. Very solid and well made. Installed on my Montblanc Timewalker with a Hirsch strap. Tried first using a Hirsch deployment buckle, but unhappy with the curvature of the clasp which was pushing into my wrist. Took a chance with an at Artem clasp after doing extensive research and reading reviews online. Happy with my purchase. Will be buying another in Black.


I use butterfly clasps on almost all my bands. I've always wanted to try one of these so I picked one up now that Mike carries them. It is a beautiful clasp and adds even more class to the Artem straps. The screw attachments are a little more work but as long as you don't plan to switch out the clasp, you should only have to do it once.
