Our Rating:

How good is the watch?

As its sibling BN0150-28E - definitely one of the best buys


  • Crystal glass is quite durable
  • Simple rotating bezel
  • Stainless steel - again --> durability


  • Watch strap is kinda small and stiff 
  • Date window feels too small
  • Several cases reported that water enters the watch - not very useful if you are taking it for a dive...  

Apart from being a fantastic addition to any diver’s list to measure the time spent underwater, a good dive watch also carries out all the functions of your regular wrist watch.

Citizen Eco-Drive Men's BN0151-09L Promaster Diver Watch With Blue PU Band

Citizen is renowned the world over as the pioneers and one of the oldest brands in watch manufacturing. Some of the most innovative, finely-crafted and precise watches have been created by Citizen.

The Promaster Series launched by Citizen in 1989, has been extremely popular among professionals and these watches have been built to endure the toughest conditions and offer excellent functionality.  

About this diver's watch - Citizen BN0151

If you’re are on the lookout for a dive watch with superior technology and cool and aesthetic looks, then the Citizen BN0151 Eco-Drive Promaster Dive Watch is a great buy.

Powered by the unique Eco-Drive Technology, the Citizen BN0151 Eco-Drive Promaster gets charged when exposed to natural or artificial light and does not require batteries to run.

How does Eco-Drive technology work?

The Eco-Drive technology makes use of a thin amorphous silicon disc to convert light energy into electric energy, which is stored in the lithium-ion battery and helps to run the watch. And, once the watch is fully charged, it will glow for hours underwater. The Eco-Drive technology makes the Citizen Eco-Drive Promaster Dive Watch environmental friendly.

The Citizen BN0151 Eco-Drive Promaster is a well-built and attractive stainless-steel watch. It is quite inexpensive and provides good value for money if you’re into water sports and any (sub)marine activities. The high-quality Japanese quartz movement of the dive watch makes it very accurate and highly durable.

The dial of the watch is made of tough mineral glass, which is resistant to scratches and bumps as the glass dial is located below the bezel which has a unidirectional rotation.

The beautiful azure blue colored dial of the Citizen BN0151 Eco-Drive Promaster has a luminescent green bezel, blue non-numeral markings and a bright orange minute hand.

This makes the dial of the watch very easy to read both underwater as well as on land.

The Citizen BN0151 Eco-Drive Promaster also features a winding crown that is located conveniently at the 8 o’clock position, which prevents it from any damage due to rough handling and prevents water from entering the watch.

The strap of the watch is made of sturdy polyurethane, which is durable and lasts even in harsh underwater conditions. On the other hand, it is actually quite stiff and you will have to get used to wearing it for a longer periods of time. Obviously, durability comes with a consequence of lower comfort.

The non-reflective coating on the dial cuts down the glare when you’re in the water and the matte finish adds to the sophisticated looks of the watch.

The Citizen BN0151 Eco-Drive Promaster is ISO-certified (read more about ISO certification in our dive watch guide).

Together with 20-bar water pressure rating and the water resistance of up to 200 meters (660 feet) makes the Citizen BN0151 Eco-Drive Promaster a fantastic buy for those who love diving, snorkeling and enjoy other water sports.
