Materials & Build
We manufacture this clasp from solid 316L stainless steel, a grade chosen for its durability and resistance to rust. Each component is precision machined to ensure the hinge operates smoothly without any rattling or loose play. The black version uses a vacuum plating process to resist scratches, while the silver option features a deep polish that matches most steel watch cases. Every edge is rounded and smoothed to prevent digging into your skin during long days at the office or formal events.

Sizing & Fit
This clasp is available in 18mm, 20mm, and 22mm widths. To find your size, measure the width of your strap at the point where it meets the buckle, as many straps taper and are narrower than the watch lugs. The mechanism accommodates straps with a thickness between 2mm and 3.5mm at the attachment point. Once installed, the clasp adds approximately 8mm of total length to your strap setup, which is easily adjusted via the strap holes.

FAQ
How do I know which size to buy for my watch?
You need to measure the width of the strap at the buckle end, not the lug end where it connects to the watch. Many 20mm straps taper down to an 18mm buckle. Use a caliper or a metric ruler to confirm the exact width of your current buckle before ordering to ensure a perfect fit.
Will this work with a thick dive strap?
This butterfly buckle is designed for straps with a thickness of up to 3.5mm at the tip. Most standard leather and silicone straps fit perfectly. However, very thick "chunk" style leather straps or heavy-duty rubber dive bands might be too thick to slide through the locking bridge of the clasp.
Is it difficult to install this clasp myself?
Installation is straightforward and usually takes less than five minutes. It uses a standard spring bar to attach to the strap, just like a regular buckle. You can use a basic spring bar tool to pop out your old buckle and click this one into place. It is a simple DIY project for any watch owner.
Does the clasp come with the necessary hardware?
Yes, each Stainless Steel Watch Clasp Butterfly Buckle includes the required spring bar for attachment. You will receive the complete assembly ready to be mounted onto your existing strap. We recommend keeping your original buckle in a safe place if you ever wish to switch back to the factory look.
Will the black finish fade over time?
The black finish is applied using an advanced PVD (Physical Vapor Deposition) process. This is much more durable than standard paint or powder coating. While it is highly resistant to scratches and fading, heavy contact with abrasive surfaces like metal desks may show wear over several years of constant use.
