One of my favorite Citizen models has always been the Promaster Tough - a watch released in various versions over the years, consistently remaining an ultra-durable modern field chronometer with a date function.
When I first learned about the Citizen Promaster Land GMT, I was immediately intrigued by this model, as it essentially represents a version of the Promaster Tough with a GMT function. However, in reality, these two models differ significantly from each other. Nevertheless, the Promaster Land GMT maintains its status as a reliable tool watch with an additional dual time zone display function.
Design and Case Materials of the Citizen Promaster Land GMT
The Citizen Promaster Land GMT visually echoes the Promaster Tough in many ways, yet the differences between them run deeper than just the presence of a second time zone. Unlike the super titanium case of the Promaster Tough, the Land GMT case is made of matte stainless steel. The model is slightly smaller in size and lacks the monocoque construction with front loading, typical of the Promaster Tough - here, the case back is classic, screw-down. Despite this, the main design principles - readability and durability - remain a priority. Additionally, the Promaster Land GMT features a screw-down crown, and the water resistance reaches an impressive 200 meters.
Dimensions and Structural Features
The Citizen Promaster Land GMT case has a diameter of 39.5 mm with a thickness of 13.5 mm, including the domed sapphire crystal that protrudes above the bezel. The lug width is 20 mm, and the overall lug-to-lug length is 45 mm. Unlike the Promaster Tough, which has drilled lug holes, the Land GMT's lug sides are smooth with a linear brushed finish. The case shape is inherited from the Promaster Tough, but the fixed bezel is adorned with an engraved 24-hour scale, serving to display the second time zone.
Execution Variants and Dial Design
At the time of writing, the Promaster Land GMT is offered in two versions: reference BJ7150-09L with a blue dial and a gray nylon strap (featured here) and reference BJ7150-50W with a red dial and a matching steel bracelet. Both variants have dials that largely repeat the design of the Promaster Tough: large Arabic numerals and a date window at the "3 o'clock" position. The dial surface is decorated with a grainy texture. The hands are similar in shape to the Promaster Tough, but the hour and minute hands lack horizontal supports for the luminescent coating. The lume has a bright blue glow, ensuring excellent readability in the dark.
Movement and GMT Functionality Features
The Citizen Promaster Land GMT is powered by the Eco-Drive B878 caliber - a quartz movement that can be recharged from any light source, not just sunlight. The modern Eco-Drive B878 is equipped with a low charge indicator (the second hand starts ticking at 2-second intervals), overcharge protection, and a quick start function after stopping in low-light conditions. Eco-Drive movements are known for their accuracy and reliability; however, the B878 caliber raises some concerns due to its unconventional GMT function implementation.
Features and Drawbacks of the GMT Complication
Unlike traditional "caller-style" GMT movements, where the date and 24-hour hand can be adjusted independently, the B878 caliber combines quick date advancement with the ability to independently set the local 12-hour hand. A similar principle is used in other Citizen GMT models, such as the Promaster Nighthawk. This approach is suitable for tracking a second time zone but not ideal for travel and frequent changes of the second zone time. The date is linked to the 12-hour hand, which creates inconvenience, as the date cannot be adjusted backward like in "flyer-style" GMT.
For example, when traveling from Los Angeles to New York with a 3-hour time difference, setting the watch upon arrival is not a problem - just pull the crown out to the first position and move the hour hand forward by 3 hours. However, on the return trip, you cannot simply move the hand back by 3 hours - you will have to advance it forward by 21 hours, which will change the date. To correct it, you will need to manually scroll the calendar disk by 30 days, making the adjustment significantly more complicated compared to classic date watches.
Comparison with Traditional GMT Movements
Moreover, the Caliber B878 is less convenient for frequent tracking of additional time zones compared to traditional "caller-style" GMT movements. In the latter, the 24-hour hand can be adjusted independently without affecting the local time and date. In the Promaster Land GMT, changing the 24-hour hand is impossible without shifting the 12-hour one. Considering that Citizen produces the popular GMT movement Miyota 9075, the Japanese manufacturer clearly understands how to create convenient GMT complications, but the solution in the B878 raises questions, as it combines neither "flyer-style" nor "caller-style" GMT advantages.
Conclusion: Advantages and Disadvantages of the Model
The Citizen Promaster Land GMT could have been a real hit if it had received an Eco-Drive with a full "flyer-style" GMT function. It can be assumed that many brands would be interested in purchasing a white-label Miyota for their watches. However, the internal workings of the model are somewhat disappointing, especially considering that the rest of the watch is executed at a high level. It would be nice to see a super titanium case without a back cover, like the Promaster Tough, but adding the GMT complication is a logical extension of the ultra-durable field watch concept, and the compact case size is commendable.
Practical Aspects of Wearing and Strap Recommendations
Apart from the contentious movement operation, I have no serious complaints about the Promaster Land GMT. In the version with the blue dial, the gray nylon NATO strap seems a bit long for wrists around 16.5-17 cm (6.5-6.75 inches) in diameter. The strap has numerous adjustment holes, but its end is not long enough to thread through the first keeper. You could simply shorten the strap end to naturally pass under the second keeper, but I recommend choosing any other 20-mm NATO strap to your liking and transferring the Citizen branded buckle to the new strap.
Conclusion: Positioning and Price
Despite criticism of the movement, the Promaster Land GMT remains one of my favorite modern Citizen models. For frequent travelers, its unique GMT implementation is not ideal, but for everyone who needs reliable and well-readable watches with the ability to display two time zones simultaneously, this model has almost no alternatives. If I owned this watch, I would leave the 24-hour hand on GMT/UTC time and calculate the difference mentally or use both hour hands for the current time zone, and the 24-hour hand as an AM/PM indicator, similar to the original Rolex Explorer II concept (reference 1655).
Citizen offers a wide price range, but the brand always demonstrates a good cost-to-quality ratio. The Citizen Promaster Land GMT starts at $525 USD for the strap version (ref. BJ7150-09L) and $595 USD for the stainless steel bracelet model (ref. BJ7150-50W). This is a very competitive price for a watch with GMT and light-powered operation. Despite some shortcomings, I would gladly wear the Promaster Land GMT every day, as it expands the basic Promaster Tough concept by adding a dual time zone function.
