Above is the Steinhart Submariner
Although the Steinhart does not try to be anything other than what it says it is the question has to be asked why buy a fake Rolex when something like the Steinhart captures the essence of the 1970's military divers watch and is a reliable product with after sales support.
Below are two more Rolex submariners with the genuine watch on the left and the fake on the right and as you can see they are very close and anyone without experience could easily be fooled.
