  • Many premium wellness apps

  • Water-resistant up to 50m

The answer to this question would be “no,” if we were to answer it literally.

However, that does not imply that the Vivoactive 4 is an ineffectively made watch; just the contrary. The truth is that a lot of people think a waterproof watch is the same as one that is water-resistant.

Before you make a purchase, you must grasp the significant difference between the two phrases.

As things stand, a waterproof watch hasn’t been invented (and it’s unlikely to be anytime soon). The most that manufacturers can do is create products that are water-resistant and can endure brief submersion times.

Numerous watches, including all models in Garmin’s line-up, include water resistance (WR). The WR will differ amongst Garmin models that offer the following ratings:

  • IP65 – can survive light spray or rain
  • IP67 – can take splashes, rain or snow, and survive a dusty environment
  • 1ATM – withstands pressures equivalent to a depth of 10 meters, fine for splashes, rain or snow, showering
  • 3ATM – withstands pressures equivalent to a depth of 30 meters, fine for splashes, rain or snow, showering, jumping into the water
  • 5ATM – withstands pressures equivalent to a depth of 50 meters, fine for splashes, rain or snow, showering, swimming, snorkeling
  • 10ATM – withstands pressures equivalent to a depth of 100 meters, fine for splashes, rain or snow, showering, swimming, diving into the water, snorkeling, high-speed water sports

So, which of the above ratings is offered by the Garmin Forerunner 45?

With a 5ATM (50m) WR rating, all Garmin Forerunner 45 versions are reliable companions for showers, short swims, or even snorkeling (in the pool).

The gadget will not have any trouble with splashes, rain, or snow.

Here it’s important to note that water resistance status should be regularly monitored. Over time, gaskets and seals may deteriorate with aggressive use, which will result in a loss of water resistance.

To stay on the safe side, you should have your watch inspected regularly (eg. once a year) by an authorized Garmin dealer to make sure it keeps its 5ATM rating.
