First, your write up is well presented and covers a few of the flaws.
In some ways I like the case. The curves make it almost like a Ressence branded watch. It helped a bit with the size. The crown shape doesn’t impress me - I prefer the older version.
The things that likely make the platinum a showstopper for me (I have the steel and the platinum on order):
1. No German silver movement. Harder to work with so I assume they cut costs but officially they tell me it doesn’t age the way they want with white cases. This was a marketing selling point in the old models so why the change in sentiment?
2. The chrono hands on the platinum other than the second hand are silver like the time hands. Why did they do this?? The gold by the way has blued hands aligned to compromise functions and silvered for time. This is different than every Duometre chrono they have made. I hate this change on the platinum.
3. The salmon is slightly off colour to me. Not sure why my eye doesn’t love it but it isn’t my favourite hew.
4. Another sticking point. JLC stopped putting deployant buckles in precious metal watches many years ago (they used to). Here they are using the white gold pin buckle on the platinum watch. They make a pin buckle in pt but aren’t using it. Feels like another short cut.
