Just got it yesterday. Awesome watch, easy to use functions. Great looking! No doubt in my mind that it will be typical excellent Citizen quality. Only reason for the 4 stars versus 5, crown is not a screw down. Seems really strange for this watch. Additionally, the crown is absent any shoulders for protection. Also strange.
First and foremost: Great utility watch. Altimeter and compass simple to use . Bezel spins freely but bearable. The liquid rubber strap I ditched for a Zulu nato strap which works brilliantly. The size is 46mm and wears like a 46mm so it is a pretty big watch. I like big watches . The lume on this particular watch does last glowing a blue hue for maybe 3hrs . I strongly recommend it .
I like this watch for its altitude reading, the lume in the dark, the compass with the click-free bidirectional rotating bezel, and its oxygen sensor. A good choice from the Citizen Promaster.
First time customer. Very well built and good quality. Hardened storage case is a nice feature. Ordering was pretty straightforward, and the shipping was fast!
