Discover the ultimate dive watches with expert reviews, in-depth guides, and exclusive insights.
Today, I’m sharing a reminder for everyone to refresh their knowledge on crown operation techniques. In a classic spy movie, I once saw a scene where two agents synchronized their analog watches down to the second before starting a mission. Though I can’t recall the title, this has me thinking: some people still adjust their…
Water resistance ratings vary between brands and models, typically expressed in meters (m), bars (bar), or atmospheres (atm or ata). Although scientific measurements differentiate between atm and ata, for standard diving at sea level, atm and ata can be treated the same (differences appear mainly in high-altitude diving). Pressure Equivalents: 1 bar ≈ 0.987 atm…
Let’s talk about when and where to use a Helium escape valve, both the automatic and manual types. I have a few diver’s watches with Helium escape valves, and the rest of my dive watches don’t have them. I’ve been diving since my military days, but back then, I hated it because I couldn’t see…
Continuing from the last post, let’s dive into another urban myth about waterproofing: “No matter how good the water resistance, watch out for steam in wet saunas because vapor can still get in.“ Before debunking this myth, let’s go over a few key concepts. Pressure Equilibrium In our physical world, two forces from different environments…
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…
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. The reason for including anti-magnetism in dive watches is to help divers dive safely underwater. Divers are exposed to environments where they can be affected by magnets. Many diving equipment items…
A chronograph refers to a watch with a stopwatch function. This function starts, stops, and resets the stopwatch by pressing a button on the watch case. It was originally invented for tracking celestial bodies, and later, with the need to measure horse racing times accurately, it became mass-produced and found use in various fields. So,…
Most dive watches have strong luminescence. However, some people looking for a dive watch are dissatisfied with its brightness. The main reason is that the glow duration is short; with Luminova, it typically lasts about 10 to 20 minutes. Some may think, “It fades in just a few minutes. Is it defective?“ “Why isn’t it…
