I hesitated to order this item due to the low asking price, but I love mechanical watches, and being reluctant to wear my Rolex in many setting these days, I decided to take a chance. I bought through Amazon, so I knew I was protected if disappointed.

I must say that when I received the watch, I was struck by the cheezy yellow box it came in. I mean, gaudy doesn't begin to describe it, but what the heck, I didn't buy a box, I bought a watch.

When I opened the box I was awe struck by the craftsmanship of the watch case, and the dial, which I quickly examined with a loupe.

The movement is the outstandingly reviewed Seiko NH35A (Seiko 4R36 when installed in Seiko watches), so what's not to like there? A real precision movement that isn't as fancy as the Rolex, or my 45 year old Galet chronometers, but it gets the job done in fine style, with the hack feature, as well as the manual-wind feature to give outstanding reserve for idle periods.

I've only had the watch a few days, but so far, the time loss per day is about -14 seconds per day (+/- 2) so in reality the watch is repeatable w/in 2sec a day, but averages 14 sec a day slow, which CAN be adjusted. To maintain +/- 2 sec per 24hrs is better than my Rolex, and exactly equal to my Bulova Accutron "tuning fork" watch of 50 years ago. It's not as good as my Casio quartz (&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Casio-AMW320R-1EV-Marine-Ana-Digi-Watch/dp/B000GB1R5U/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Casio AMW320R 1EV Marine Ana Digi Watch</a>&nbsp;) to which I added a stainless bracelet, which manages 2 sec/month, but hey, we are talking a mechanical watch, and I'd have been happy with +/- 15sec per day!

So if you've hesitated to buy this, or any other Invicta diver with THIS movement, I think you can be sure that if I love mine, as critical as I am, the you will LOVE it just as much.

My only question is: HOW does Invicta do it for the money?

Update #1: I've now allowed the watch to "break-in" by running for a couple of months, and surprisingly, it maintained the average 14 sec/day loss within +/-1.5 sec. I took the back off the watch, and in TINY increments began adjusting the speed regulating lever. It is MUCH more sensitive than any other watch I ever regulated, with about 2/1000" of pointer movement making a 20sec/day change! It took about a dozen frustrating adjustments back and forth (then monitoring the watch for 6 hours minimum), but I now have the watch maintaining nearly perfect time to where in the first 3 full days after replacing the back and wearing the watch. By perfect, I mean it is within 1 seconds total in that time, then lost another second on the 4th day. I decided to manually wind the watch to see what would happen, and found that a full manual wind caused the watch to GAIN a second in 12 hours. So now I know that if the watch loses a second, all I have to do is to manually wind it (rather than trying to reset it), and it should re-gain the lost second. To say that this is outstanding, almost phenomenal, accuracy for a mechanical movement of ANY price is accurate! Did I mention that I LOVE this watch?

Oh, yes, one problem- The very small luminous dot at the "12 o'clock" position on the bezel fell (not inside the case), or was knocked off. The watch looks the same to me, so no big deal.

My wife found my watch attractive, so I purchased her a women's version of the same watch case, but with a Quartz movement. She has no particular interest in mechanical movements, and just wanted an accurate watch out-of-the-box. I bought her the Invicta 8942 Womens' Dive Watch, which is visually identical except that the face and the bezel is blue, rather than black. She is quite delighted, and it's been a reliable watch so far.

UPDATE #2: Since regulating the watch exactly 2 weeks ago, I have kept daily track of it's ability to be accurate, and in 14 days the watch is precisely 7 seconds slow. It has lost between ZERO and One Second per day over this period (meaning a +/- 1/2 second per day consistency), which I am blown away by. This is without playing any games (like manually winding it) and the watch is worn 24/7.
This Seiko Automatic Movement is an absolute wonder and a joy to behold, and would EASILY meet ANY Swiss Chronometer Certification (only about 4-5% of the finest Switch watches can pass the test), though of course they would refuse to even TEST it because it is not made in Switzerland, so doesn't pass the "Snob Test." [...]

UPDATE #3: Unfortunately, after enjoying almost perfect time-keeping, I failed to remove my watch when qualifying at the range, and the recoil evidently altered the regulation of my watch. It is sadly now tracking about 10 sec/day slow, so I will have to open the back, and re-regulate it. It is very consistent, so I am sure just tweaking the adjustment slightly will put it spot-on again. My most accurate watch (a "Swiss Military" chronograph with a Swiss quartz movement I've owned for 10 years) is "off" by only 2 seconds after 3 months, and HAS sustained recoil shock w/ no adverse effects, but that is a wholly unrealistic expectation from an automatic mechanical watch. I am STILL delighted with the Invicta, however.
