I believe its ceramic, thats one part I havent looked too much into 

I would personally say the PRX. I dont think the Gentleman has enough going for it. In a way I feel like it almost looks too simple and generic to justify the price tag. Just my thoughts though 

I must say the power reserve is one of my main reasons for considering it. Watches like my Seiko SRPE53 go dead far too often

I see what you mean about the Royal Oak but I think that's probably contributed to a large amount of the PRX's sales. Definitely like your choice going for the black dial version 

Now they are incredibly intriguing. The 40mm of the PRX from last year seemed Ok but with such a large lug to lug size it just didn't work for me. Definitely looking forward to these releasing properly 

I agree, Tissot's value for money is really up there with the likes of Seiko and Orient

Thats fair enough, I can see why it wouldn't be for everyone
