About Dive Watches

Dive watches are trendy because you can trust they will not be easily dented, scratched, or broken. Dive watches are built to withstand these conditions, making them perfect for professional divers and adventurers.

Citizen Promaster 1000M Professional Diver Review

The first thing that catches your eye when you first see this Citizen watch is the case. This 52.5mm x 21.4mm case is built with Citizen’s “Super Titanium” alliance for scratch resistance, lightweight, and durability.

The bezel is coated with Diamond-Like Carbon (DLC), and the sapphire crystal has an anti-reflective coating. The bezel has a ‘saw blade’ design, so it can be rotated easily, even when wearing thick diving gloves. This unidirectional bezel features an elapsed time display and lock.

The locking mechanism prevents the bezel from accidentally bumping and affecting the accuracy of the elapsed time display. You may see an orange strip when the lock is unlocked. This visual indication tells you exactly when the bezel is locked in place. A similar orange strip can be seen when the screw-down crown is loosened.


This dive watch has a date display at 3 o’clock and a power reserve indicator at 9 o’clock. The power reserve indicator lets divers dive worry-free because they know precisely how long the watch runs without lights. The Citizen Promaster 1000M Professional Diver watch also has a helium release valve at 10 o’clock on the side of the case.

This helium release valve releases helium gas that enters the watch during deep diving, preventing damage or rupture of the movement. As you may have noticed, the hour markers are pretty significant.

The added lumens and increased size make the time easy to read, even in less-than-ideal conditions. The outline of the minute hand is bright orange, making it easy to distinguish between the hour and minute hands.

Citizen bn7020 17e Movement

As for the movement, this dive watch has a solar-powered movement with an accuracy of +/- 15 seconds per month. This Eco-Drive One movement can convert any light (natural or artificial) into energy, which is stored in a power cell.

Because the watch can store energy, the watch will continue to work even if kept in the dark (at least six months). The best thing about solar watches is that you don’t have to worry about replacing batteries.

ISO compliant

If you’re looking for a tested dive watch, you’ll be happy to know that the Citizen Promaster 1000M Professional Diver is ISO-compliant.


The Citizen Promaster 1000M Professional Diver watch can be a bit heavy, but it’s stylish in a way that’s industrial and mechanical can. A watch with an adventurer motif makes you feel as if you are discovering the world.

What is ISO compliant, and what are its Requirements?

ISO watch is a certified diving watch tested to ensure it is resistant to saltwater and reliable even underwater. ISO 6425 certification also performs tests for resistance to magnetism, impact resistance, external force resistance, and thermal shock resistance.

Finally, there is a test to see if the watch continues to work after spending 15 days in a pressurized chamber. This chamber contains a mixture of helium and oxygen (or 100% helium gas) and returns to atmospheric pressure within 3 minutes after high-speed decompression.

If the watch passes these stringent requirements, it may display a depth rating after the word “diver.” In this case, the Citizen Promaster Diver is marked “Professional Diver’s 1000m” on the side of the case.

ISO Certification Requirements:

  1. The watch must be equipped with a device that allows the user to preselect a time of up to 60 minutes. This can be a rotating bezel or a digital display.
  2. Timing devices must be protected against accidental manipulation.
  3. The bezel should have a scale showing 60 minutes, with an indicator showing every 5 minutes.
  4. The markings on the dial must be visible and in harmony with the markings on the preselection device.
  5. The time should be visible, and the minute hand should be easily distinguishable from the hour hand.
  6. The time set on the preselector must be precise as an indication that time is passing (this requirement is usually met by a glowing hand and an hour mark).
  7. A battery-operated watch must have a visible low-battery indicator.
