Materials & Build
Each adapter is milled from solid 316L stainless steel to ensure it survives daily bumps and exposure to the elements. We maintain a tolerance of 0.05mm to ensure the locking pin clicks securely into your Apple Watch every time. The silver version features a brushed finish to match the aluminum or steel cases, while the black version uses a vacuum-plated PVD coating that resists scratches and maintains its deep matte look.

FAQ
Will this fit my Apple Watch Ultra 2?
Yes, the 42/44/45mm size option is fully compatible with the 49mm Apple Watch Ultra and Ultra 2. The locking mechanism is identical across these larger case sizes, ensuring a flush and secure fit for your rugged outdoor adventures.
Is it waterproof and shower-safe?
Absolutely. Since these are made from 316L stainless steel, they will not rust or degrade when exposed to fresh water, salt water, or sweat. We recommend rinsing them with fresh water after a swim to keep the finish looking clean and prevent salt buildup.
How do I install the adapter?
Installation is a two-step process. First, slide the adapter into your Apple Watch until you hear it click. Second, use a standard spring bar tool to attach your chosen watch strap to the adapter bridge. It works exactly like a traditional watch lug once it is clicked into the case.
What if it doesn't fit my strap?
We offer a 30-day return policy if the adapter does not meet your needs. Most standard straps use 20mm or 22mm widths, but if you have an unusual strap size, please measure the width before ordering to ensure the spring bar will fit through the adapter loop.
Does the metal cause skin allergies?
We use 316L stainless steel, which is the industry standard for surgical equipment and high-end horology. It is low-nickel and generally safe for those with metal sensitivities. The PVD coating on the black version provides an additional barrier between the steel and your skin.
