Only in the study of several customer reviews I got it, that this clock, deceptively similar to the other case back with glass window, the Invicta brand logo and a few other little things, a famous Swiss luxury clock for around 10,000 EUR looks, but without a Replica to be.
A view of the rotor through the glass window in the screwed caseback shows the Seiko factory NH35A SII. Only this offers the advantage of an extra lift, which makes a watch winder superfluous.
A first test over several days resulted in an accuracy of + 15 sec. / Day. That's not bad, but can be by a watchmaker enhanced by fine adjustment.
Even with critical examination I could not detect any defects in workmanship. The clock is a gem! There remains the hope that it is also waterproof for swimming and snorkeling. According to various tables the indicated water depth is 200 meters mandatory for this application.
The clock came with a label with price tag $ 345.00 and cost of Amazon Free Shipping 99.99 EUR. This low price can actually be only explained by the fact that it is according to Amazon to an outdated model.
The included universal manual in English does not fit with this clock. The additional hand wound is not mentioned. For the enjoyment of 1-year warranty on the clock Invicta needs to be returned to Hollywood / USA. That you can forget (shipping, if applicable customs, etc.). One can only hope that the warranty case never occurs.
Delivery by Amazon was as usual very fast. Two days after ordering the clock was there.
Supplement for accuracy:
Meanwhile, the clock was re-adjusted by a watchmaker. You can compete with a quartz watch now quite. She is now in 4 days just 1 second before.
