To this day, it has remained faithful to the original. It was designed and built by Charles Von Bren at a time when diving watches were just beginning to appear, with its 50 atm of pressure resistance, guaranteeing peace of mind to all underwater exploration enthusiasts. The crown at four oclock Functionality in every detail The position of the crown at four oclock has over the years become one of the trademarks of the SQUALE brand. Much more than just an aesthetic detail, it was designed in this way to avoid accidental knocks during a dive, which could cause it to become unscrewed, damaging the watch. The bezel with 120 click adjustment Maximum precision for diving safety The one way, 120 click non slip ridged bezel guarantees maximum safety during diving: this allows you to adjust the time with maximum precision by aligning the triangle of the bezel to the desired minute. The orange minute hand Maximum visibility in extreme conditions The minute hand is most important for a diver, as it allows you to monitor the minutes spent underwater, essential information to be able to accurately calculate decompression times during ascent. For this reason it is essential that it is easily distinguishable from the other hands due to its unique colour. The choice of orange is not accidental: it is in fact the colour that is best seen in low light conditions with poor visibility.
