This may be more of a personal perspective because it fit me, but I was looking for more of a fitment like the RLX Daytona and it felt too large when making that comparison.
Since I am here, I will weigh in on your other questions: I, for one, will not wear my watches in any wet environment (including a shower), unless they have a resistance rating of 100m (10atm) or better. Supposedly, 3atm is okay for showering, but I don't feel comfortable with that, especially with a piece that costs north of $50k.
As far as pricing, I don't know about this particular piece, but I have an opinion about FPJ in today's market. I believe these pieces are still undervalued and a fair comparison can be made to any artist who is renowned in his lifetime, such as Picasso. After he passed away, the work he did became extraordinarily valuable. While you may no longer be able to flip an FPJ for a quick profit in a year or two, if you hold it for the long term, it is still a value play as I see it. Also, there is an argument that relative to the dress pieces by Francois, the sport pieces are still somewhat undervalued because he entered the market making dress pieces and veteran FPJ collectors have resisted the ones like you are asking about here.
