CTS Deployant Clasp
If you're here, we know you're hooked on our CTS Rubber straps. We've got choices for you to pair them with different watch case materials!
The CTS Deployant Clasp comes in 2 different metals (316L Steel and Titanium Grade 2), a total of 6 different colours & finishing, and in 3 widths for Steel (16mm, 18mm, 20mm), 2 widths for Titanium (16mm, 18mm). Weight difference between the two different metals:
- Silver (Steel), 16mm: 13.7g
- Gunmetal (Titanium), 16mm: 10.0g
16 Dec 2025: Now available in an engraved Mosaic finish, this Mosaic option adds a new textural dimension to the CTS Deployant Clasp. Designed and engraved in-house, it brings a fresh way to personalise your CTS straps. Produced in limited quantities – available while stocks last.
Note: These clasps are designed for exclusive use with our CTS Rubber Straps and do not fit any other straps, including our regular selection.
Our CTS Rubber Straps are tapered (for example, 20-16). If you want to purchase the deployant clasp for your strap, make sure you purchase the tapered width (16mm), and not the lug width (20mm). If you are unsure, drop us a message and we'll be glad to help out.
For ease of installation, you may also want to consider a spring bar tool to help you swap out the clasps.
Now Featuring the Mosaic Pattern
Extending the Mosaic Design
Building on our patterned CTS Rubber Straps, we've extended the mosaic pattern to our clasp. Whether you have the plain strap or the mosaic one, this clasp is sure to add a unique artistic flair to any outfit.
Engraved In-House
Designed and engraved in-house, the Mosaic clasp introduces a refined textured pattern that adds dimension and plays with light from every angle.
What customers say
4.8/5 — the clasp knock-offs copy but don't match: 'I ensure you they are not made with such attention to detail.' The butterfly mechanism adds elegance to any CTS rubber strap, and service earns as much praise as the hardware.
