A nice four watch Citizen collection could be a Promaster Land, Sea, Air and maybe an automatic like the Tsuyosa or Zenshin. For the Air, I was drawn to the idea of a Blue Angels watch. I give this one a 95 out of 100. Any watch with this many complications will have some trade offs in legibility. The high points are the radio control time accuracy with perpetual calendar (set and forget), highly legible analog time, legible slide rule, eco-drive power meter, UTC analog subdial and second city digital option. One trade off is that you can either display the second city, or the date (the date is for UTC). The leather band is very good, and very dark blue. This watch wears well with black, tan, blue, brown, white or grey, so it is highly versatile.
This watch has a lot to recommend. 1. It looks great 2. it's 100% accurate 3. Battery never needs to be replaced 4. Powerful features, including Universal Time, 12- or 24-hour time 5. Calendar with day and date 6. 42 world regions 7. LED lights 8. Looks great 9. Great strap in leather 10. For the price, great value
My second Blue Angle watch, first one bought by my daughter and wife 27years ago. It finally became OBE. My new one is gorgeous but not as easy to use, I’m sure I’ll learn.
This watch is amazing. I haven't had any issues since I received it 7 months ago at Christmas time... best time piece yet.
