Is the Bunker compatible with my Galaxy Watch?

The Bunker is only compatible with Samsung Galaxy Watch Ultra (2024 and 2025). It is not compatible with other Galaxy Watch models.

Is the Bunker easy to install?

Yes. Its proprietary attachment system can be installed in seconds on compatible Galaxy Watch Ultra models, with no tools required.

Can the Bunker cause irritation if I sweat a lot?

The Bunker's silicone is treated to remain comfortable with prolonged contact. To avoid any discomfort, rinse it after exercise, adjust it slightly looser, and let your skin breathe once a day. These actions significantly reduce the risk of irritation sometimes encountered with silicone.

Why choose the Bunker?

A thick, textured silicone that takes on rough terrain without getting marked by rocks or a backpack strap.

Despite its thickness it stays supple, and it does not stiffen in low temperatures.

Three outdoor colors: black, orange and white. A rinse after a muddy outing is all it needs.

Every model is checked on the listed watches before it goes on sale. That is what separates a strap you chose from a strap you happened upon. You buy your first strap to see if it holds up. You choose the second one for style.

Wear it for two weeks. It is up to the strap to prove itself, not you.

THE FIGURES, NOT THE PROMISES

Plenty of choice. No doubt.
