Do I need an adapter or tools?

Gaskets (and tools where pictured) are included. The watch module transfers from the stock case into the new case — no adapter required.

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?

Measure your watch’s lug width before ordering and pick the closest size in the options.
