Under no circumstances should you buy the titanium strap QuickFit 26 Ref 010-12580-00. The locking pin on the €300 strap has broken in two years, and Garmin says it's beyond repair and not covered by the warranty.

In my case the pin used for shortening the strap fell out, I lost a crucial, irreplaceable link. At least the watch was not lost. Definitely not a great piece of engineering.

Garmin's latest response is that the titanium strap is a "consumable" item and only has a 6-month warranty :-(

That depends on the legislation of the country where you live. In the Netherlands, for example, a legal warranty of 2 years applies for all products.
And yes, the legislation of a country takes precedence over what Garmin thinks about it.

My 2018 titanium band came with my Fenix 5 Pro in 2018 and I've been using it since. It may not be the exact same band as the one you have, though, as they bands were $250 back then. I did buy a set of watch tools kit and the kit came with a bunch of locking pins of different sizes and would just use one of them if I had an issue on my band.

That said, I noticed that Abenen sells a titanium band for $39 and I like their nylon bands so I would buy one of those if I needed a replacement.
