I know that several forum members own this watch but after one week of wearing, I am impressed with everything about this model.
The movement is the SW200 and after 1 week of wearing the accuracy is 35 seconds fast. That is awfully good for the first week of wear.
I had ordered this watch twice before only to cancel because I was concerned about the double spring bar rubber strap and the advertised size of the watch, I believe 46 mm. After one week on the wrist, it is so comfortable, the rubber strap allows for a near perfect fit, and the elongated piston-look crown does not dig into my hand at all.
I was also concerned about star shaped caseback being uncomfortable but because of the angle of the end links, the watch rides nicely on the wrist.
I purchased the plain sstl bezel version and the colors on the dial actually are quite pronounced since the contrast is greater with the plain bezel. The dashboard design is quite unique and attractive. The guilloche type work on a portion of the dial gives it a very expensive look. I have had several people inquire about the watch and where I got it.
The rubber strap is stiff yet comfortable. The strap keeper is integrated into the double tang buckle which is also a unique design touch.
I love this watch. . . it is a great time piece by Invicta. I do wonder why an automatic three hand watch needs a tachymeter on the dial. Also, the date window at the 9 o'clock position is a bit small. Otherwise, this model is in my top 5 favorites of any watch I own and I give the company high marks. Getting it on clearance with free shipping also helped my positive opinion.
