Thanks for tha tag
@Feefo, I would like to start by saying that whilst I do love Daytonas and frankly obsess over them day to day, I am by no means an expert on the subject, and there are plenty of other members on the forum more knowledgeable than I.
Now to answer your question, I would need a little more info as to what exactly you are after, and what your budget is?
If price isn't an issue and you really want the best of the best, I don't think to many would object to Clean as being your main option. BTF also produce some great quality Daytona reps but I think that Clean's more gen like YG plating and (imo) superior dials makes them the obvious choice out of the 2. I have a Clean 116518ln black dial on a custom leather strap that I absolutely adore, and have owned the 116518ln with the gold dial/black subdials which is honestly one of the best rep Daytonas I have ever owned OTB.
There are a couple of mid range options available however these are all based off of the A7750, which from experience is not a great movement for the Daytona, they are prone to failure, chrono does not work like gen and the case is a little fatter too. If the 116508 is a watch you really want to own then I think spending the extra to get a Clean version is absolutely worth it. BTF as a viable second choice if you can get a good deal on one.
