Great watch! My only quartz pro diver, which is handy since it's always ready to go without winding and setting. I miss having a date function when I wear it, but for me it's actually for the better since I store/display watches in rotations with the crown pulled to save the battery. All I have to do is quick set time w/o worrying about date or am/pm.

Quality: top grade stainless steel and solid links. This looks like a $1000 watch. I get stares and comments all the time. One nice thing about this pro diver, if you have any other invicta divers, it does not have the INVICTA engraved on the side. The chrono is not the type that has the sweep second rest at 12 until stop watch is used. I prefer that since I'd rather see the big sweeping second hand running than a little mini dial. Although I never need a stop watch chrono it's fun to have. If I ever need to time something I use the unidirectional bezel. The movement itself is a Seiko quartz.

Testing: good idea to test the limits of every watch when you first get it so if it fails within its specifications you can return it immediately. All watch brands can send a lemon or have broken seals.
I have not taken this particular watch swimming but had it in boiling hot tub, left for 24hrs in 125g aquarium (~3 feet), 12hrs in saltwater tank without rinsing after to watch for corrosion of inferior stainless. There is none. After each water test it goes right in refrigerator (80 degrees to 33) to check for fogging under crystal. Passed all tests! Don't worry about non screw down crown. There are gasket seals that do fine.
The "flame fusion" crystal may be a weird marketing name but it works great! Not one scratch and by all means should have. Beads off water droplets quick too!
Definitely a buy! Make sure you add a 22mm NATO strap to the order too for when you want to change the attitude of the look.
