So many companies make a watch that look like a Rolex of one sort or another, I'm not too bothered unless it's a true fake with Rolex on the dial and is being passed off as the real thing. I can't say with any certainty (and I don't think anyone else can either) if the watches are made in a facility that also produces fakes. In this case I doubt it. Is Seiko also making counterfeit Rolexes when they make a model that resembles a Datejust? Bulova used to make one like this also as did many other fairly major manufacturers. I don't think that watches that look like someone else's model are always produced by fakers.
I have worked on a few of the Steinhart/DeBaufre watches that resemble Rolex models. One I can think of off the top of my head is the Ocean 1 model.
Overall they are decently made watches, and the models I have had in the shop have been fitted with ETA 2892A2's - one might have been a GMT with a 2893-2. 2 or 3 of the watches that came to me were defective in some manner or another, and the warranty support was not really great from the company. No one in Canada to go to for warranty work, so they brought the watches to me and I fixed them, and they asked for reimbursement from the company - I know at least 1 person did get the money back. That was for a faulty automatic winding mechanism.
I have had 2 of these watches fail pressure testing using a proper dive watch testing process. This involves high pressure wet testing to 125% of the rating on the watch. I now refuse to do this testing on them because they fail - the only 2 I tested this way both failed. I believe personally it's because the case backs are quite thin and very flat, so they don't hold up to the pressure and deflect inwards and cause the seals to leak. Mind you this is at 37.5 bar, so not a problem for most people and they are still good for swimming if properly cared for.
I seem to get a lot of requests to remove the Cyclops off the crystals - not sure why people buy it if they don't like the Cyclops!
Anyway, not bad watches, but in no way equivalent to the watches they are "paying homage" to.
