Our Citizen Promaster BN0151-09L Review

The Citizen BN0151-09L is the kind of watch that will definitely come to your liking as soon as you set your eyes on it. Apart from the fact that it’s an I.S.O certified dive watch, this watch is an absolute beauty. Even if you’re not into diving, this watch will surely up your outfit game whilst complimenting your wrist perfectly. Without further ado, let’s dive into the facts that make this watch one of the best watches under $500

The Design

One of the main reasons this watch took place on our favorites list is its magnificent design. The blue colored dial (azure blue to be specific) accompanied by the dark blue bezel is definitely eye soothing. The stainless-steel case certifies that the watch can take a beating. Moreover, the perfectly positioned markers and the luminous watch hands make sure you can read the time even under the direst circumstances.

The case diameter is 44m and the anti-reflective coated mineral crystal glass makes it scratch-resistant. The case diameter makes the lug of the watch short but not too short so it hugs your wrist perfectly. The date marker and the crown are positioned at 4’o clock, giving it a unique vibe. The position of the crown makes it really convenient to use. However, we felt that the date window could’ve been a bit larger.

The basic model comes with a blue molded polyurethane strap with stainless steel buckle. We’ve used generic leather straps and NATOs to check and they both fit in perfectly. So, it is safe to say that even though the Promaster doesn’t come with strap variants, you can use any straps that have a width of approx. 19 millimeters. However, we prefer the basic one that comes with the watch over others.

Additionally, if you’re looking for a different color, the BN0150-28E model of the same series comes with a black dial and a black strap (offers the same functionality).

Another great feature of the Citizen Promaster is the accuracy of the watch. The BN0151-09L not only provides us with an accurate time but also provides accurate dive tracking.

It comes with a Japanese Quartz movement and claimed to be capable of +/- 15 seconds per month accuracy. Since the watch runs on ECO-Drive technology, it can last up to 6 months with a full charge. The watch even has a two-second interval mode that is automatically activated when it’s low on the power reserve.

The Promaster BN0151-09L comes with a unidirectional bezel with markers that are perfectly synced with the chapter ring. The bezel contains both ten-minute and five-minute increments for accurate dive tracking. The outer area of the bezel comes with a unique design that provides a better grip for the users. However, unlike the watch glass, the bezel gets easily scratched.

Citizen Eco-Drive

While Citizen has done a great job designing the BN0151-09L, the most unique feature that we found during our research for the Citizen Promaster Diver review is the ECO-drive technology. We are huge fans of Citizen Eco-Drive technology and believe that it's one of the best things that happened to the world of horology.

The Citizen Promaster comes with the E168 version of the Eco-Drive. As a result, you don’t have to worry about battery life at all. How the technology works is that it uses a rechargeable battery and stores power from any kind of light inside. Even keeping it under a table lamp for a few hours will fully charge the battery.

The BN0151-09L has some light amorphous silicon discs under the dial that act as energy converters. Although they are situated right underneath the main dial, they are invisible to the naked eye. So, another thumbs up for Citizen!

Comfort and Ease of Use

Considering the fact that it’s a dive watch, the Citizen Promaster is pretty light. And the 12mm thickness of the case gives it a slim profile, making it comfortable to wear throughout the day. Moreover, users can even wear it comfortably on top of diving gloves.

As we’ve already mentioned before, the dial is meticulously designed so that it’s convenient for the user to read the time. In addition, the three distinctive hands (hour, minute, and second) help out in this regard as well. The unique markers positioned at 3,6,9, and 12 make it easy to check the time quickly at a glance.

The position of the crown makes it very user-friendly. Although most of us are habituated with using the crown at the 3’o clock position, the 4’o clock crown makes it easier to set the date and time. Just like other quartz watches, the crown moves the date at the first unscrewed position and alters the time at the second. Additionally, the signature Promaster arrow logo can be found engraved on the crown.
