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.
