Looks big—an excellent tool watch with many functions but hardened titanium makes the watch both light and durable. Not scratch proof but better than stainless steel, by a fair amount. Waited a long time for a sapphire crystal and this one now has it! Plus accurate—GPS—I set my other watches, including my A0100 and Chronomaster by this piece. Perpetual calendar, timer, alarm, LED backlight (could stay on longer but it’s also Eco-drive, so no batteries or winder needed, just a little light now and again.) Oh, and all this for less than $800! Pretty spectacular, Citizen.
Watch does what it is supposed to do... keep accurate time and does it perfectly. However the extra money paid for things like slide rule bezel was not worth it. Citizen documentation to use the bezel did not support the watch itself... there were even English language errors in the documentation customer service sent to help which further complicated and added to my frustration. I returned the watch and when I am eventually refunded, I will likely purchase another citizen AT absent the slide rule bezel feature at lower price.
