According to the manufacturer's specifications, the adjustment strap is 110 mm long and the buckle strap is 84 mm long. An alternative would be the dive strap version: Garmin QuickFit 20 (20 mm, silicone)
Here the adjustment strap is 124 mm long. The buckle strap is 93 mm long and the long adjustment strap is 263 mm long.
The QuickFit wristband with the product ID "010-12863-02" is not specifically designed for the Garmin Forerunner 265. It is compatible with models such as the Approach S60, fenix 5, fenix 5 Plus, fenix 6, fenix 6 Pro, Forerunner 935, quatix 5 and quatix 5 Sapphire. However, there are other compatible wristbands specially developed for the Forerunner 265.
The Fenix 7X also has a 51mm case diameter, so it should also have 26mm Quickfit straps. I think that should work. I also have the 26mm straps on my Descent MK3i with 51mm diameter and also have a titanium strap on it, which was for an older model.
