Citizen has produced, over the years, and still does, watches featuring cutting-edge technology and excellent product reliability, geared towards the accessible market segment. The Japanese have set industry standards, especially among sports watches, that many other watch companies have then successfully applied. The Citizen Promaster collection's most recent evolution.

We are a few days away from Baselworld 2019's opening ceremony, and I'm willing to share with you a few notes about the untold story behind the origins of the Promaster collection and what we might expect Citizen to launch on this extraordinary occasion, including some product previews. If you love Citizen watches, whether they are those powered by an Eco- Drive movement or a robust (and virtually unstoppable) Miyota mechanical movement, there's no doubt that the Citizen Promaster collection is the technological pinnacle of the brand's offering, and a successful story that turns 30 this year.

The movement isn’t breaking any records, but at its core is supporting the professional focus of the watch, providing a workhorse power supply for its timekeeping and dive-ready functionality.The history of the Citizen Promaster collection is one of the most exciting in the history of Citizen watches and the world of diving and sports watches too. The movement is accurate to +/- 15 seconds per month, and is capable of running for two continuous months when fully charged and removed from light. Powering the professional diver is the Citizen Caliber B740, an Eco-Drive movement powered by light. Overall, the dial is clearly aimed at the serious professional diver, with a chronograph scale limited to recording a 50-minute dive time and no longer intervals its depth gauge featuring depth increments commonly used by divers (3, 6, 9, 12, and 15 meters, etc.), and its hands and color accents designed for legibility even in the murkiest of conditions. The dial also features a 6 o’clock subdial for running seconds, with an on-brand design inspired by a submarine’s sonar screen. A 24-hour indicator on the left side sits parallel to the 3 o’clock date window. The watch’s chronograph functionality is front-and-center, both in the red-tipped seconds counter at the center of the dial and in a 50-minute subdial placed near the 12 o’clock position.The indicator for the aforementioned depth gauge, capable of measuring up to 50 meters underwater, curves along the outer edge.

At first glance, it’s obvious the dial is designed with professional divers’ use in mind: its contrasting features place the foremost attention on legibility and functionality, rather than on trendier stylistic elements found in many other dive watches.


Underneath the sapphire crystal is an an equally distinctive dial that matches the hardy look of the case. The other details of the 200-meter water-resistant case include a bold-looking 60-minute unidirectional diving bezel, where we find the first major pop of color: its three three distinct colorways are blue, DLC red, and DLC green.
