I have a few rolexes and seikos and older protreks . I've been eyeing these new protreks for a while. when casio released the bonfire edition I had to get it. it's been the only big watch I can tolerate while riding a mountain bike. the others have always destroyed (made me bleed) my wrist.. I actually tore a garmin watch off my wrist during one ride and threw that $400 piece of trash into the woods. this model protrek is square , not round and it is light weight AND it has a rubber strap that keeps it where it is supposed to be. It has solar power, radio atomic automatic whatever time keeping that adjusts itself every day... my rolexes ... honestly are garbage compared to this when it comes to accuracy and actual time keeping. this watch is awesome. AND IT HAS A FRIGGIN light on it so I can check the time after I turn the lights out... it has red lime on the face and hands too which is dope... but can't beat a light and you know this man... if you have had watches with just lume on them you know that stuff sucks.. I don't care if it's tritium or "really bright lume" it still sucks compared to a light and you know it. the way that this watch operates is really hands on and is satisfying to manipulate the functions and change settings. the way casio has combined analog and digital is next level with this one. "but it doesn't have a heart rate monitor or a step counter boo hoo"... I know when my heart rate is in the red because I ride a mountain bike every day... I don't give a flip how many steps I have taken in a day because I'm not obese enough to worry about it. "but it doesn't have GPS"...I've had garmin watches with GPS... they suck. everyone of you that owns a garmin watch with gps knows this too. use your phone gps...screen is bigger . this watch is as durable as any G-shock , it's a tank. if you are looking at casio protrek watches , this is the one. pick a color combo and buy it, you will love it.
