With some calculation and remembering or checking the decompression tables, with the Citizen Promaster Aqualand Depth Meter you are able to accurately determine if you should perform decompression stops. This is important as one of the main factors of staying in the no-decompression limits for a dive are your maximum depth achieved and the amount of time spent at bottom as well as overall time in water and prior dives. What makes this feature interesting for divers is the ease of knowing what max depth you have achieved during a dive as you check for your dive time. The first one indicates the current depth in meters and the other moves along but remains at the greatest depth achieved.įor instance, in the picture above, you can see that I was at about 8 meters (26 feet) depth, whereas my max depth at the time was about 10 meters (or about 33 feet). If you look carefully at the dial above, you will see that besides the two skeletonized hands in white (indicating hours) and orange (indicating minutes), there are two other smaller hands shaped as pointy arrows in blue and purple.
What makes the Citizen Promaster Aqualand particularly usable to me for diving are two unique features that are most commonly found in either dive computers or mechanical watches ten times the price of this one: a depth gauge with indication of current depth and max depth. So far, I can attest that the battery charging has worked perfectly as the watch remained pretty much fully charged (easily seen by the power reserve indicator on the dial) since I received it a couple of weeks before the trip, and the sun in Florida constantly recharged it as I used it for diving. In the model I received, containing the Eco-Drive J250 movement, one charge will typically hold the watch working for 180 days and more (by going to standby mode) if the watch is kept in a poorly lit enclosure. This makes for an accurate watch that requires very low maintenance. The great part about this technology is that watch can be powered by any light, solar, home light, and so on, and the battery is typically rated and guaranteed for a the lifetime of the watch. What follows here is a recap of three days diving with the Citizen Eco-Drive Promaster Aqualand diver.Ĭitizen is well known for their quartz watches, however, the Citizen company has a long history in horology dating back to 1924 producing pocket watches under the name Citizen but branded by Shokosha Watch Research Institute.Ĭurrently the most popular lineup from Citizen stems from their Eco-Drive watches which use a solar cell on the dial to charge a battery and fuel an accurate quartz movement. As I venture into eventually becoming a master diver, I did not hesitate when Citizen wanted to send me one exemplar for my second trip to Key Largo, FL, in the past three years to dive in the marine sanctuary there.
One of the most affordable, yet feature packed, dive watches with a depth gauge is the Citizen Eco-Drive Promaster Aqualand Depth Meter reference BN2029-01E (or Citizen Promaster Aqualand for short).
