If you are looking for an affordable and beautifully designed dive watch that is accurate and robust, the Citizen BN0151-09L Eco-Drive is definitely a watch to consider. The Citizen BN0151-09L can instantly be recognized as a sporty dive watch, but this is not because it looks like a Submariner. In fact, it has a unique design, but it offers everything you may need in a dive watch, and it offers this at a very attractive price. It has a great water-resistance, has large applied markers and hands, a generous amount of luminous material, and a unidirectional rotating bezel.
The Citizen BN0151-09L has a robust and sporty stainless steel case with a diameter of 44mm. Including the crown, the diameter is 48mm. The case design is quite simple with short lugs and a satin finish both on the upper side and the side of the case. Unlike many other watches, it does not have polished sides, but considering its sporty look, satin-brushed sides are appropriate. The watch has a lug-to-lug
Sitting on top of the case is a bezel with large knurled edges on some parts around it. Casio chose not to do knurled edges around the whole bezel, but those that exist help you get a good grip when operating it. The watch has a blue aluminum bezel insert with silver markers. In some lights, this bezel insert looks black, and in others a brighter blue. At 12 o'clock, it has a lume pip so you can read it in the dark.
Positioned at 4 o'clock, we find the screw-down crown. This is protected by small crown guards. Due to the small crown guards, the crown is not fully protected, so this could potentially put the crown at risk. At the same time, The 4 o'clock position means that it does not sit as exposed as a crown at 3 o'clock. The small crown guards also help make the case less bulky, and the shape of the case to remain round.
The case has a thickness of 12mm and a lug width of 20mm. With all of the case's dimensions in mind, it is a large watch, but it is not huge. The good thing is that because the lugs are relatively short, they rarely point out from the wrist unless you have very small wrists, which is the primary reason why certain watches look too big on people.
The watch offers a water-resistance of 200M which is enough for diving, swimming and doing all sorts of water activities. It is also ISO-certified.
Moving on to the dial of this watch, we find that the dial has everything you need in a dive watch. The dial is slightly matte and dark blue which prevents reflects but also helps add some texture. The watch has applied metal markers, with triangle-shaped markers at 3, 6, 9, and 12, and circular markers for the rest of the hours. The markers have a generous amount of luminous material applied to them which provides a strong and bright glow in the dark. The hands are broad and easy to read. To help distinguish them, the minute hand has been painted orange. This creates a nice contrast against the otherwise blue watch and is the only additional color used. The hand has an arrow tip. The watch is presented on a dark blue polyurethane strap and not a bracelet. Similar to rubber or silicone, it is very soft and suitable for a dive watch. The strap looks great on this watch and definitely adds to its dive-watch look.
If you are looking for high quality and original dive watch that offers great value for money at an affordable price, the Citizen BN0151-09L Eco-Drive Promaster is definitely a watch you won't be disappointed with.
