What is a Diver Watch and which are its characteristics?

Hello everyone,

The arrival of spring and the first coffees at a sunny terrace remind us of summer, that is about to come. We are sure that many of you will decide to spend the holidays in a place where you can disconnect and freshen up nearby the river or sea. Because of this, it is time to switch the urban automatic watch and the diver watch ready to resist all your adventures. Do you know which are the main characteristics of a diver watch?

which are the differences between a diver watch and a water-resistant watch?

First of all, it is necessary to emphasize that not all water-resistant watches are a diver watch. A waterproof or water-resistan watch is distinguished by having a certain level of resistance to the humidity and preassure of aquatic immersions. The hermeticism of the quartz or automatic watch will define its features and resistance, as well as the materials in which it is made. As an example, we must highlight that only stainless steel watches will resist salt water immersions.

However, the technical features of a diver watch are far more complex and they must comply with certain regulations and standards, such as the ISO 6425.

ISO 6425 STANDARD OF A Diver WATCH

ISO 6425 is a regulation that defines the characteristics of diver watches and ensures that it has been tested in order to guarantee its correct functioning and quality. Among the required features are:

  • Water resistance depth.The hermetic nature of a diver watch must be at least 100 m, this is, 10 atm. AS an example, the Alpina Seastrong Diver 300 automatic watch resistance is 30 atm.
  • Time measuring system to control the time of immersion. A diver watch must have a scale minutes gyratory bezel that can be locked to avoid involuntary rotations. By lining up the bezel with the hand at the moment of the immersion, we will be able to know the time we have been underwater only taking a look at the bezel.
  • If we want to distinguish the hands and numbers of the watch, it must incorporate lume components to glow in the dark. Moreover, according to ISO 6425, the watch should be readible in the dark at a 25 cm distance.
  • Other feature of diver watches is the magnetic resistance. As an example, the Ball Engineer Master II Diver Worldtime Automatic Watch has an antimagnetic 4800 m/A system.
  • Every diver watch must have been subjected to shock tests in order to ensure its shock resistance. This is the case of the Sinn Diver EZM 3 automatic watch.
  • Of course, it must be salt water resistant. To test this, manufactures use to leave the watch in a NaCl solution for 24 hours. That is the reason why a commonly used material in the case and bracelet of diver watches is stainless steel, as the Seiko Prospex Special Edition Automatic Watch.
  • In a diver watch it must be indicated in the dial DiverWatchas well as its hermiticism values.
Other remarkable features of a diver watch
  • Diver watches usually incorporate a screw-down crown
  • Some professional diver watches have an helium release valve to make up for the preassure differences during the diving ascent. These watches have been designed to resist outer and inner preassure changes while diving, to prevent the crystal from breaking or shattering. To avoid the decompression syndrome of professional divers, the manufacturers introduced a helium escape valve inside the watches.
