Do I need any other parts?

No extra parts needed — this adapter converts your watch’s lug mount to standard spring bars. A spring-bar tool helps but the install is about 5 minutes.

How long does shipping take?

US and EU warehouses ship in 7–12 days; worldwide orders 12–20 days, fully tracked. Free express shipping over $39.

What strap width do I need?

This piece comes in 18/20/22mm — match it to your watch’s lug width before ordering.
