Well, I purchased my first replica watch. Since I've owned a 126660 Deep Sea, I decided to get a replica of that since I'm very familiar with the model, weight, size & details. I found a site that promised "1 to 1" copies of the original version. It was "on sale" for 180.00. Obviously my expectations were fairly low going in but I really wanted to see what it truly was. It finally arrived & I was first impressed with the weight, feels exactly the same on my wrist as the original did. The case & dial really are very nice. The thickness of the numbers on the rotating bezel seem to be a bit thinner than original. The bezel action is very smooth & has almost zero backlash. The band doesn't have the glide lock nor the divers extension but since it's not waterproof, the extension would be useless. The clasp is honestly, junk. Very flimsy& cheap. I've since ordered a black rubber band for it. They also advised me to remove it when washing my hands. Lol. It actually keeps fantastic time, much better than my original even after they serviced it under warranty. After one week, it is 6 seconds fast. If you shake it enough, you can actually hear it winding itself but, if it's on the watch winder, it does not wind & will stop after 36 hours. I honestly couldn't tell you which "factory" version this is, there is nothing in the paperwork to identify that. So overall, it appears pretty close to an original, keeps great time & passed the sniff test wearing it to a business function. We'll see how long it lasts. Have a great day. Edit, I forgot a couple of things. The PIP? Pretty bad. It looks like a raised pimple if you know what it truly should look like. The Lume? What lume? Lol. It doesn't matter how long it's charged with a light source, there is no lume.
