Questions about this item

Will the 41 mm case sit comfortably next to a traditional 40 mm watch on the same wrist?

The 41 mm case is only 1 mm wider than a classic 40 mm size, so both watches share nearly identical wrist presence and will not feel unbalanced when worn together.

How can I confirm the Actua 360 display and dual-frequency GPS are active after the first sync?

Open the display settings to verify the 360-degree always-on mode is enabled, then start an outdoor workout — the workout summary will show a dual-frequency GPS lock indicator once the route is recorded.

Does the box include the side charging dock and the Obsidian Active Band, or must I buy either separately?

The Matte Black Aluminum case ships with the Obsidian Active Band already attached and the new side charging dock in the box, so no extra purchase is needed for either item.
