Ternos Ceramic Automatic 200m Blue Diving Watch 16155540

The best way to measure your wrist size is not to measure it at all – and we’re explaining to you why.
Wrists and arms come in many shapes and structures, from thin to large, from flat to round, so the key to check if the watch fits is to determine how it suits your arm.
To calculate it, rest your arm on a flat surface like your desktop, without pressing down, and measure your wrist size end-to-end with a caliper. That’s the recommended maximum size of the watch, calculated on the full extension of the lugs (not the case diameter). Anything more is too much: it would seem like you’re wearing your big brother’s watch. Anything less is instead acceptable: remember that man’s dress watch size in the Fifties was around 32 mm (so, a smaller vintage watch would fit a larger wrist without looking lost). The perfect fit is when the ends of the lugs touch the silhouette of your wrist.
While in the Noughties watch size increased absurdly, reaching almost unwearable dimensions over 50 mm, the primary trend of the industry is to return to a smaller scale: the last launches of the major Maisons were around 41 mm, which usually optically “fills” the majority of wrists.

• “How deep can a diver watch go?”

Most of the watches usually show on their dials or their backs an indication like “XX meters water-resistant.”
The cardinal rule is that this is true, but only under specific conditions.
This measurement refers to the pressure that the sealing gaskets of the watch can withstand if subject to a static position. This means that if you attach a 30-meter water-resistant watch to a wire and slowly uncoil it, the watch could resist the water pressure that happens at a depth of 30 meters – that is, 3 bar.
However, it does not take into consideration the dynamic pressure that a watch is subject to. For example, the simple pressure of the water from your bathroom faucet is around 3 bar, and the pressure from your shower head reaches 4.5 bar.
A swimmer who swims freestyle submits his watch to a pressure of around 5 bar.
So, if you want to buy a watch, please remember that the minimum water resistance to be used around water safely is 100 meters (10 bar). If you plan to do apnea skin-diving, it is advised a water-resistance of 150 meters. If you plan to do recreational diving, 200 meters are better. And finally, if you are a pro diver, consider professional diver watches with a water resistance of 300 meters or more and a helium escape valve.

• “How to use a diver watch bezel?”

The rotating diver watch bezel was designed to help divers check how much time they can pass underwater.
Its function is simple: before the diver starts his dive, he aligns the 12 o’clock bezel marker with the minute hand to visually show the descent’s elapsed time to be read on the bezel (up to 60 minutes). Consider that most dives take less than 50 minutes: as every descent is carefully planned before, a diver knows how much autonomy he has, including the mandatory decompression stops.
Coupled with the unidirectional construction of the bezel, this ensures that your watch would not display an incorrect measurement, making the stay underwater more than the time allowed by the air in your tanks.
Most diver watches bezels show a highlighted zone on the first 15 to 20 minutes on the bezel inlay: this is the moment when divers usually start their return to the airworld.
Some older watches’ bezels report different indications: divers used them to calculate decompression stops on the fly.
Today, they represent more a legacy to the old times of scuba diving than a necessity, as diving computers have replaced watches. Still, a professional diver’s watch is a mandatory backup for a diving computer – and it looks much nicer on the wrist when you relax at the bar with your friends after your dive.
