30 ATM vs 30 Metres Explained: Vaiana Express Reveals Own Listing Error

Vaiana Express corrects 129 Guess watch listings after finding a unit-conversion error confusing 30 ATM with 30 metres, clarifying water resistance ratings for watch buyers.

Staten Island, United States, September 17, 2026 /NewsNetwork/ -- Vaiana Express has completed an internal audit of its Guess watch listings and corrected a unit-conversion error affecting water resistance ratings. The company reviewed 201 Guess watches in its catalog and updated 129 listings after identifying that some product descriptions misstated depth ratings in metres as if they were rated in ATM.

The distinction matters because ATM and metres are not interchangeable units, despite how often they appear side by side on a spec sheet. One ATM equals roughly ten metres. That means a watch rated 30 ATM can withstand pressure equivalent to 300 metres, while a watch rated 30 metres withstands only about 3 ATM, a tenfold gap that can lead buyers to assume a watch handles far more water exposure than it actually does.

A rating of 30 metres generally covers splashes, rain, and hand washing, not showering or swimming, according to watch industry guidance. A 50-metre rating extends to showering and light swimming, though water sports remain outside its scope, and sources in the watch industry caution that watches rated at 30 metres should stay out of pools and open water altogether.

Even accurate ratings can overstate real-world protection because they come from static pressure tests conducted in controlled conditions. Swimming strokes, forceful impacts, and hot showers can generate pressure fluctuations that exceed a watch's stated rating, industry observers note, which helps explain why practical guidance for wearers is often more conservative than the number printed on the case back.

The error traced back to a supplier data field labeled ATM - 30, which was misread as 30 ATM instead of its intended meaning of 30 metres. Once identified, Vaiana Express reviewed all 201 Guess watches in its catalog and corrected 129 listings, adding clear metre-to-ATM equivalents alongside plain-language usage guidance for each rating.

Vaiana Express sources its watches, including TAG Heuer, Movado, Michael Kors, and Emporio Armani, through authorized dealer relationships and works to keep specifications accurate across its catalog. The company also notes that gaskets degrade over time due to age, temperature swings, and chemical exposure, which can lower a watch's real-world water resistance below its original rating; a screw-down crown, by contrast, typically signals a stronger seal than a push-pull crown found on lower-rated watches.

Buyers with questions about a specific watch's water resistance rating are encouraged to review current listings or contact customer support directly. Vaiana Express continues to audit its catalog for accuracy as part of its ongoing effort toward clear, dependable product information.
