Do I need an adapter?

Yes — the GA-2100 uses a proprietary lug mount, so a 22mm strap adapter is required (sold separately in the Adapters collection). Install takes about 5 minutes with a spring-bar tool.

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 26mm — match it to your watch’s lug width before ordering.
