I have had the privilege to own both the 5146 in J & G with the same coloured dial,as in your photo. It is a great piece and one that I wish in many ways I had hung onto, the subdials give it that, imo, a more vintage feel. And as Carl has pointed out, I find the PR a more useful complication then the 24 hr hand, which only main use, again imo is when setting the watch. The luminous hands, may appear out of sorts with the rest of the watches vintage look, but nonetheless I found it most useful at night.
Now, the 5205, which I have discussed on many occasions, is the more modern version of the 5146 with the exact same movement, apart from having a silicone part installed (apologise, as I can't remember its name!) & virtually the same module fitted on top, I say virtually because you have to take into account the PR over the 24 hour hand.
I very much like the layout of the dial, especially the apertures, and the case, with its "Torpedo Tube" as I call them, design, is a first and was designed by, I believe Thierry's wife.
The colour of the dial has been discussed many, many times by both me and others. The black dial is absolutely gorgeous and is normally my favourite. However recently the legibility of the black with the W/G hands has caused me a few niggles. And if I remember correctly, I did touch upon that item, in a previous review that I wrote about the watch.Last week I got to see again the lighter dial and it was an immediate hit with me. And hopefully while my 5205 is with the service centre, will get the dial changed.
Also bear in mind that the 5146 comes with a deployant clasp over a tang buckle.
If I had to choice between the two, it would be a very, very difficult decision, but if pushed, the lighter dial 5205 would possibly win, but only possibly.
At the end of the day Anders, whichever one you go for, imo, YOU JUST CAN"T LOOSE
