I purchased this watch after seeing it online on Amazon and thought it looked very similar to the Rolex Submariner.  For less that $100, I thought "Why not? If it's junk I can return it or keep it as a thrasher watch."  Well, I was very surprised. The 8926 is a sharp looking watch! It's heavy, solidly built with thick solid bracelet and clean very Rolex-like dial.  This version has the Japanese automatic movement from Seiko, movement NH25A (my watch is engraved 8926A on the back case). The auto-wind rotor is etched with SII and Seiko "dot" logo on the right side and NH25A on the left side along with "twenty one jewels" on the center. There are other miscellaneous engravings on the rotor.

I own several automatic watches that I can wind manually by turning the crown. When I tried to wind this watch manually, it didn't do anything. I didn't feel it engage the  mainspring... the crown just spun freely. A look through the manual didn't mention anything about the Seiko NH25A movement so I thought perhaps the watch was defective because the crown wouldn't engage the mainspring for manual winding. I decided to check the SII website, specifically the NH25A specification and discovered that this movement doesn't have manual winding capability. It's 100% automatic and must be wound by movement of the rotor. I wonder how many people returned this watch thinking it was defective!

Anyway, I put the watch in a watch winder and let it go for 24 hours (timed auto rotation mode)and it's been running flawlessly since.  I read how some owners were disappointed that their 8926 reserve time is less than 8 hours.  I let mine wind down to see how long the reserve time is and it went a full 36 hours before it stopped.  I put it back in the watch winder and let it fully wind up and it's been running non-stop for over a month as a daily wearer. I take the watch off at night and let it sit for 8 to 10 hours per day and it hasn't stopped once.  I've pretty much stopped wearing my other watches (I have 45 of them).

My 8926A has been running very accurately.  In little over month and half, I've only reset the time twice my moving the minute hand back 2 minutes each time.  Either I got very lucky with this movement's regulation or Seiko NH25A is an excellent movement!  I like my Invicta 8926A so much and have been so impressed with Invicta quality, I went and bought more.  I now have the following...

8926 Japan Automatic S/S (stainless steel) scalloped edge bezel
9307 Swiss Quarts S/S scalloped edge bezel
9310 Swiss Quartz S/S Gold scalloped edge bezel
9937 Swiss Automatic S/S coin-edge bezel (aka Rolex style)
9938 Swiss Automatic S/S Gold coin-edge bezel (aka Rolex style)

All of them are running flawlessly.

UPDATE: 9/23/13

My Invicta 8926 has been running non-stop and flawlessly since I bought it over a year ago.  During that time, I let it wind down only three times just to see what the reserve time is and it's right around 30 - 35 hours. When I'm not wearing the watch, it's in an auto-winder.  I don't like getting my watches wet because I hate the wet clammy feeling under the watch on my wrist and I have to take the watch off anyway to dry it, so I generally won't soak the watch to begin with, especially if it has leather band. Having read the customers review that complained about the water resistance of their Invicta watches, I decided to soak mine... in the shower and in a cup of water overnight. No damage visible and watch keeps perfect time.  Maybe I'm lucky?  Now, that was before I opened the case back to regulate the watch.  The gasket still looked good when I put the case back back on but as for its water tightness now, I don't know and I don't care because I'm not going to soak it diving down to 660 feet. The watch crystal, bezel, case and most of the links still look very shiny and in excellent condition except for the clasp which is completely scratched up from being dragged across desks.  It's taken few very hard hits and hasn't suffered any shock damage. Overall, I was so pleased with my Invicta, I bought many more instead of dropping a lot of money on one Swiss-Made brand name watch... I researched a lot about the Swiss watch industry and now I refuse to fall for the marketing scam.  I work with several people who are watch snobs and they pretty much laugh at the Invicta brand or any thing else that doesn't cost upwards of $5000 and up.  Can someone tell me why Breitling, Tag Heuer, Tissot and Rolex cost so much, especially if its just stainless steel and not precious metal case??

Just a bit of rambling now.

Over the past year, I've sort of lost my mind and became a watch fanatic... I now own about 300 watches and the last tally on purchases surpassed $10,000.  I became fascinated with the whole watch industry and watchmaking/repairs and decided to study Horology as a hobby.  For one, the whole Swiss Made quality thing is a marketing scam. I delved into the whole manufacturing/marketing thing and learned that really there is only a handful of movement manufacturers in Switzerland (Swatch Group being one of the largest {ETA movements}) that supply most of the movements to other manufacturers.  Some of the EXPENSIVE name brand watches use "upgraded" movement parts that you'd find in lower priced watches. I can understand the "upgrading" of the parts but how do they justify the incredible cost? It's all in the name. I bet you'll be surprised to learn that a lot of Swiss watches are made with parts supplied by companies outside of Switzerland and "finished" in Switzerland.  As long as it's 50% cost of assembly of the movement in Switzerland, it's considered Swiss Movement.  It doesn't matter where the parts came from (China). Now, of course there are some Swiss watch manufacturers that make everything in-house and don't share anything, but it's only a handful. So, with this dose of skepticism, I bought many watches to test and evaluate, priced from about $15.00 to over $1000.00. I also bought a timing machine and various watchmaker tools and gained enough knowledge to be able to take apart and repair mechanical watches (as well as quartz watches.) Sapphire crystal is the rage on watches... so I decided to replace quite a few of them on my personally owned watches... and discovered that they aren't that expensive at all.  In Los Angeles Jewelry District, I bought many genuine sapphire crystals from dealers that supply watch parts to repair shops for about $10.00 to $35.00 per piece depending on size and thickness, most of them being in the $10 - $15 mark. It takes me less than 5 minutes to swap out the mineral glass with the sapphire glass. I also buy watch batteries for about 50 cents per piece instead of $4.00 to $5.00 per piece you'd find at repair shops. Shows you what kind of profit they are making... Using my timing machine, I have regulated my mechanical watches to accuracy within +/-5 seconds or better per day. My Invicta 8926 with the NH25A Seiko movement has been regulated to within +/-2 seconds per day. It took me about 30 minutes of measuring and adjusting the balance to get this accurate and it was done measuring the timing with dial up, dial down, 12H up, 12H down, 3H up (crown up), 3H down, averaging positional error. The watch also has 0.1 mSec beat timing error or better depending on positioning, which is good. It means the tick and the tock of the watch is timed almost perfectly.  I could have paid thousands of dollars for ONE watch bearing famous Swiss name to get this type of accuracy, but then, I would have learned that I was ripped off just for the bragging rights to say "I own a (insert expensive name watch here)."  I even bought a tourbillon watch to test it for timing accuracy and... surprise... it's no more accurate than my other $100 - $500 watches.  Now, I will admit that some of my mechanical watches were very very difficult to regulate because they just wouldn't hold adjustment.  But it was more of an exception than the rule.  Those watches I use to practice taking apart and reassembly... and I have broken a few of them.  Quartz watches, in general, are very accurate. I've been timing them using timing signal from Fort Collins, Colorado for accuracy and from my no-name $15 quartz watch to my Philips Watch (Swiss Made)and my Movados (and all in-between from Chinese, Japanese and Swiss)have all been within 5 seconds per month or better with an exception of a few that have been off my almost 8 to 10 seconds per month. In other words, in a year, the worse timed quartz watch will be off by 2 minutes.  I can live with that.  Oh, and I'm still adding to my watch collection.  Yes, I have lost my mind...  :)
