As I mentioned before the issue around the distortion is a detail that is getting more and more misunderstood in terms of replication.
Since the Fiddy was introduced the issue of distortion amongst gen owners has been high on the list of complaints.. indeed OP had to try and justify the design and Bonnetti spent a lot of time answering those complaints.
There have been a number of Fiddy crystal versions at least 4 and possibly more due to replacement but certainly 4 during the 1950 run. All of them suffered distortion to varying degrees and there was talk at one time of OP changing the dial design by moving the indices in by 3.5mm to offset the level of distortion.
There were also variations in the AR, it is commonly accepted that the AR hue remained constant in terms of colour however several Risti reported that their own Fiddy’s had a greenish AR… though this was never confirmed but was agreed by several owners.
I have never seen a green hue but that doesn’t mean it doesn’t exist, however I have had enough gen Crystals in my hand to know that the distortion and Purply hue did vary..I also had a Fiddy OEM replacement which was clear or grey at worst.
There was a comparison on Risti some time back of 3 Fiddy’s one in the 600s, one in the 1000’s and one in the 1600s…all of them were different in distortion and AR.
However none of them varied in actual shape when viewed from the side and from the top.
There are hundreds if not thousands of posts by gen owners and buyers (I shit you not) who have complained about the distortion of the Fiddy crystals. So if you are making this decision on the basis of a personal view then that’s fine But if you are making it on the basis of being gen like then you are completely wrong to do so.
The idea that anyone here with a rep Fiddy gets hung up on distortion is a trap to be avoided, the key is the shape.. the distortion is minor in comparison. As we are talking about those ‘that know’ (not the guessers) I guarantee that anyone viewing the watch on your wrist will spot the shape before they can possibly judge the distortion. The fact is distortion on the gens especially in the first batches was terrible and just, if not more distorted than the Noob crystal.
Another key point to remember in judging crystals is that pictorial reference is generally misleading, as with a lot of rep comparisons. But you can only really know this once you have held a few gen crystals in your hand. The thing to remember with those pics is that they are taken on the whole to reduce the level of distortion or AR..to highlight the dial etc. So 99% of what you see is trying to hide the level of distortion on the gens.
As an aside back in 2005 there was talk of the Fiddy value dropping from RRP due to the distortion first noted..some guys even sold at reduced prices which I am sure they now regret !!

. Other owners actually replaced their crystals with custom crystals or Rad crystals. I recall a guy called Tieg or Fieg that offered gen owners replacement flat crystals.
Of course there is the other major part of the rep crystals compared to the gens and that is simply the material and method of construction.
There are as I am sure some of you will know a myriad of crystal materials for watch crystals and in respect of the OP Fiddy crystal these were a high quality corundum crystal manufactured from a single piece of grown crystal. It was a multi stage process which relied on some serious machinery and processes to complete to the standard required… then there is the rep crystal…this is of course a cheaper and more opaque crystal which is synthetically grown …the consistent key to any rep crystal is not the quality but is the effect the crystal gives compared to gen and if it looks close and is cheap to produce then its good enough…you cannot underestimate just how much of an importance this is to any rep crystal but especially the Fiddy crystal.
Any good rep crystal should have the look of the gen in terms of shape and opacity then you look at the way the crystal sits against and from the top of the bezel and the angle of lay against the watch case …the distortion is a fools folly in respect of those other details.
A good crystal should more than anything have that crystal within a crystal look and when light hits it you should see almost a round area (like a round table sitting on a crystal wall) stopping instantly at the drop points of the crystal..you should not see the light follow round the walls of the crystal…
As you view the crystal from the angle you should see a thick edge of crystal from the top of the crystal sitting against the walls of the crystal… like one of those Damin Hirst models that he sits in glass…
The truth is none of the crystal made for reps is good enough ..we all know that… however to compare a WSO crystal or DSN crystal or the like with the Noob on the basis of distortion is a mistake and wholly incorrect. On that basis it is simply a ‘six of one and half dozen of another’……
Remember though the above is not relevant so much to the MM crystal that is another story.
Note the way the light reflects against the curviature of the crystal...
