The story of The Little Prince was dreamed up by Antoine de Saint-Exupéry, a national hero to the French, a beloved author to children, and a pioneering pilot to aviation enthusiasts. It turns out he'd have an impact on horology as well.

Watch Water Resistance: A Definitive Guide to the Rating A Guide to Water Resistance - Bob's Watches Tariff troubles aside, are happy days really here again for Swiss watchmakers? The folks with the data, there and here, seem to think so.

A watch rated at 10 ATM is equivalent to 100 meters of water resistance. This means it can withstand the pressure of water at a depth of 100 meters, which is approximately 330 feet. However, it's important to note that this rating is based on static testing in a lab environment, and actual usage may vary. For practical purposes, a 10 ATM watch is suitable for swimming, snorkeling, and similar activities, but not for deep diving replica Richard Mille rm 22 Now I will say, this is a very easy watch to love in most respects; it's a living, ticking memorial to a kind of quiet excellence in watchmaking that's become increasingly rare, as mechanical watches have increasingly become luxuries, and high luxuries at that – and which in consequence need more and more to overtly signal their cost and exclusivity. Jul 18, 2025 · The ‘10 Bar Water Resistant’ is also commonly referred to as 10 ATM, meaning that the watch can withstand the equivalent of 100 meters of water. Sounds impressive, but the ‘100 meters’ is the result of a static test in a lab, not that you can actually dive to a depth of 100 meters with it. ISO 6425is an international standard for dive watches that was introduced in 1996 by the International Organization for Standardization (ISO). This standard specifies requirements for watches intended to be used underwater. The most important one is that it must be at least 100 meters water - resistant , which means that it must be able to withstand p... The watch’s water resistance rating indicates how much pressure the watch can withstand before water seeps in. It’s usually measured in ATM (atmospheres) or meters of depth, but other units are used as well, such as feet and bar. The water resistance rating is usually marked on the caseback of watches but sometimes features on the dial as well. So,... Now we know that if a watch is “waterproof,” it will withstand the stated water pressure. But what about water - resistant watches that aren’t waterproof? To what extent can, for example, a 30m water - resistant watch be in contact with water ? Or what about the 200m watch? Although water - resistant watches are not waterproof to indicated depths, they st... When a watch is waterproof, it is sealed from the water intruding into the mechanism. Such a watch has been rigorously tested and comes with watertight gaskets that prevent the water from entering. So, a waterproof watch with a 200m rating ensures the timepiece can withstand the pressure in real-life conditions 200m deep in the ocean. However, it m... What a “ water - resistant ” rating on a watch actually meansis that a sample of brand new models have received a pressure test in still water for a limited period of time. As a result, not every watch goes through the procedure. To take the matter further – water - resistant watches haven’t been tested in real-life conditions, i.e., in salty and moving...

1) Don’t wear your watch when showering– unless you like to take cold showers without using any shampoos or shower gels, it is not a good idea to take your watch with you. The thing is that watches and hot water don’t go well together because when the water cools down, the moist air absorbs into the watch case. When done constantly, the movement st... So, what to make of the watch’s water resistance rating? First off, the resistance stated on the caseback and dialis not the depth you can submerge the watchbecause it is not tested in real-life conditions. The actual limitations are far more stringent when a 30m water - resistant watch withstands only splashes of water , and a 100m water - resistant wa... Sep 3, 2024 · For a watch, 10 ATM means that it can withstand a pressure of 10 bar or the pressure of a water column of 100 meters. In practice, this corresponds to the pressure of a flowing jet of water when washing hands, showering or bathing. 10 ATM means the device can withstand pressure equivalent to a depth of 100 meters or 330 feet. A watch with a 10ATM rating is suitable for swimming, snorkeling, and other water sports that do not involve high-speed water or deep submersion. Jan 15, 2026 · Water resistance in watches comes in three interchangeable measurements: ATM (atmospheres), meters , and bars. Here’s the simple math: 1 ATM = 10 meters = 1 pressure bar. To make the complicated water resistance ratings and their suggested ways of use easier to understand, have a look at the following chart. 2 days ago · What Does “ ATM ” Mean? ATM (atmospheres) refers to the pressure a watch can withstand. 1 ATM ≈ pressure at 10 meters (33 feet) of water. So a watch rated for 10 Bar is the same as 330 feet or 100 meters. Below is a chart that shows what you can expect your watch to handle based on its depth rating: If you watch doesn't specify, or is a vintage piece, for the most part these fall into the 'no water' category.
