Citizen Promaster Aqualand

In 1986 Citizen released the innovative and groundbreaking Aqualand Dive Watch with integrated electronic depth gauge. An iconic watch with analogue hands and a digital readout for the depth. The Citizen Aqualand is immediately recognisable by it’s protruding pressure sensor on the left hand side – at the 9 o’clock position.

The Citizen Promaster Aqualand

The model above is the Citizen Promaster Aqualand 200m BN2029-01E. Note the depth sensor on the left and the 70m depth display around the inner ring of the face. The blue outlined arrow hand is CURRENT depth, the small thin hand pointing to 9 is recorded MAXIMUM depth of this dive. This functional timepiece also features a power reserve indicator (it’s Eco-Drive powered) plus a rapid ascent alarm. It’s also – as you might expect – ISO6425 compliant

If you want your Promaster to come equipped with a depth meter – then search for the Promaster Aqualand. From the current collection there are several to choose from including these particular product code

  • BN2029-01E – shown above (all analogue display)
  • JV0030-19F (analogue & digital display)
  • JV0030-01E (analogue & digital display)

Classic Promaster Aqualand – JP2000

Citizen JP2000-08E

The classic style of the Promaster Aqualand is shown above. A true icon of a watch in the diving fraternity with ISO 6425 certification. Unfortunately this model – the Citizen JP2000-08E – is now discontinued after being in production since 1992. However, it is still available from stores such as (as of Feb 2019)

When buying a used model it is quite difficult to determine the year of manufacture. At we have read various threads relating to serial numbers – but none seem to be decisive / authoratitive. If you are really lucky you might find a NOS model (new old stock) – still boxed etc. Remember – the JP2000 has a quartz movement – if it’s had a battery change there is a chance the water resistancy may have been compromised.

Citizen Promaster Diver

The Citizen dive watches without a depth meter are vaguely grouped in to the category of Citizen Promaster diver. This group mainly consists of 200m dive watches equipped with Citizen’s Eco-Drive movement. There are also some legacy models that feature an automatic movement – but these are quite hard to find – they were discontinued several years ago. We have listed some popular product codes below to help you find the model of your choice.

Note – if you want accuracy from your watch then go for an Eco-Drive model. Solar energy is used to charge a battery giving quartz watch accuracy without the hassle of changing batteries every 12 – 24 month.

Four very popular models – shown above – come from the Citizen Eco-Drive Diver’s 200m range. These models feature Citizen’s much acclaimed Eco-Drive system. High quality dive watch for less than £300 / US$300. If you are buying one on eBay make sure you can’t get a NEW one for less than a used one. We’ve seen these new for less than £250 / US$250 – so shop around. Amazon sell these models at very competitive prices – check here

These watches conform to the ISO 6425 dive watch certification and being Eco-Drive means they should never need to be opened. Unlike a quartz watch that needs a battery change – an Eco-Drive watch can remain factory sealed unless it needs repairing. The benefit of buying such a model on eBay is obvious – there is no reason what it’s water resistancy shouldn’t be as good as the day it left the factory.

Promaster Diver Automatic

No longer in production – the Citizen NY0040 series of dive watch may become a modern collectible in the not too distant future. Utilising the 8203 automatic movement this model is automatically wound by natural movement of your wrist throughout the day.

Many people, myself included, appreciate the mechanical workings of this style of watch. Like all other models in the Promaster range this one is water resistant to 200m and conforms to the ISO6425 diving watch standard.

Introduction to Citizen Promaster watches

Ask a diver to think of an affordable, quality dive watch and the brand most likely quoted will be Seiko – and rightly so. Seiko have decades of history making high quality dive watches at “everyday” prices. We don’t hide the fact that are great fans of the Seiko dive watch range

Note – all images courtesy of Citizen Watches (1)

But don’t forget the other Japanese chronometer giant – Citizen. In my personal collection I have a Citizen Promaster Divers 200m BN0191-55L (price check) with Eco-Drive movement. A true alternative to the entry level and mid-range Seiko watches the Citizen range likewise offer great value for money and typically high standards of build quality.

Popular models

The Promaster dive watch range from Citizen is not as comprehensive as that offered by Seiko Prospex. However, it has two main product lines – the Citizen Promaster Aqualand and the Citizen Promaster Diver’s 200m covering most people’s requirements. The Aqualand models feature a depth sensor, either analogue (hands) or digital. The Diver models are all 200m water resistant (or more) – such as the Promaster Diver Professional – WR to 1000m and featuring a helium escape valve.

Current models – available movements

The Citizen range has a limited number of options with regard to the internal movement of the watch. Seiko cover all tastes with their Quartz, Automatic, Solar and Kinetic dive watches. Citizen offer only their Eco-Drive movements. There are some older Automatic models (such as the NY0040) on eBay and even some “new old stock” models. The NY0040 could be something of a collector’s model in the future.

Citizen Watch Movements > FAQ


A Quartz movement relies on a small coincell battery to power the watch. Depending on the particular model the battery should last between 8 – 60 months. Remember – if you have the battery changed in your quartz watch youwould be advised to ask about the water resistancy. A professional / Citizen accredited jeweller should be able to provide assurances regarding water resistancy following a battery change.

I have now had a couple of Eco-Drive watches and I have been very impressed with their reliability and accuract. Currently in my own collection of I have a Citizen Promaster 200m BN0191-55L with Eco-Drive movement. How does Eco-Drive work …. in Citizen’s own words ..

Citizen EcoDrive technology harnesses the power of light – from any natural or artificial light source – and converts it into energy, which is stored in a permanently rechargeable solar cell. An EcoDrive watches recharges itself in any kind of light, to run forever

An automatic watch relies on movement of the wrist to keep it ticking. Simply put, every time your wrist moves a semi-circular rotor spins – in effect – winding the watch’s mainspring. The movement does not have to be forced, it works from natural gestures expressed throughout the day.

Some watches also allow for “hacking” – the manual winding of the watch to give it a headstart. Unfortunately, the NY0040 is non-hacking – so it will need a wake up shake if you haven’t worn it for a couple of days. Just swing it back an forth for a couple of minutes. Waving it around frantically does NOT help – just move your arm in a slow flag wave movement.
