How to Read and Understand Water Resistance Ratings for Watches
Water resistance ratings vary between brands and models, typically expressed in meters (m), bars (bar), or atmospheres (atm or ata).

Series : Urban Myths About Watches – Waterproofing, Part 1
I’m going to address some urban myths related to wristwatches. For this first part, I’ll talk about two myths concerning waterproofing. “If you move your hand in water or underwater, it puts tremendous pressure on the watch.” This is a well-known myth in both the East and the West. The origin of this idea is…
Dive Watches and Anti-Magnetism
The certification standards for dive watches include anti-magnetic properties. Referring to the well-known ISO 6425 diver’s watch standard, there are requirements concerning magnetic resistance.
