The Citizen Promaster Diver, or EcoZilla as it’s affectionately called, is a massive watch in every way. It’s tall, it’s wide, it’s chunky, but… similar to the Seiko Tuna it wears pretty trimly. I believe this is largely to do with how compact it is lug-to-lug. The strap descends immediately down from the lug (or lug adaptor) instead of arching across your wrist. In my experience this makes the watch wear smaller than it “should.”
It’s a no-nonsense tool watch and that’s what it lives for.
The Eco-Drive technology that Citizen uses is something that they have been developing for a long time. It’s part of their efforts to make watches that are powered strictly by the sun. In 2007 Citizen estimated that they have avoided the disposal of over 10m watch batteries by using the Eco-Drive movement, a remarkable feat if that figure is accurate.
The movement itself is pretty straightforward, quartz regulated, with a date complication. The Citizen Calibre B873 boasts an impressive 180-day power reserve, so… if the watch was exposed to bright sunlight it would take 11 hours to fully charge, on a cloudy day 40 hours, and 8” under a 30w fluorescent bulb 130 hours. Which seems like a lot until you realize that unless you lock it in a light-tight box, it will always be passively absorbing some energy. Anyway, very cool tech, and a good workhorse of a movement. According to the writing on the case-back, it’s anti-magnetic as well.
