Apple quietly published a patent for new waterproofing tech back in April this year, which now makes sense due to watchOS9’s advanced fitness metrics and multisport capabilities.
The patent, which we covered at the time it was published, showcases a ‘smart water detector’ which uses a thin membrane to detect if water has entered the device. This system would be more accurate than Apple’s current water resistance technology, allowing it to safely shut down or run water-ejection programs automatically.
Apple Watch Series 7 currently has a water resistance rating of 50 meters under ISO standard 22810:2010 (opens in new tab). In theory, the new water detection systems would allow Apple Watch users to plumb even further depths, or spend even more time in the water with increased security.
Based on what we saw in watchOS9, it sounds as though Apple’s making a move into the adventure watch space, taking on the likes of Casio G-Shock and Garmin. We’ve already written about Apple’s move into Garmin’s space with its running metrics.
