The PC I found sits up quite chunky for its size...maybe it's partly an optical illusion because it's all dial, but also I think it's quite flat and just stands tall for me. But. As a chrono I prefer it nevertheless. If a bit more meat and less formality is fine, then I think the PC has a very clear and pleasing identity. It's more distinctive and interesting.
There are JLC Masters that are prettier than the Master Chrono, I think. Not that this isn't pretty, it's just a bit unsure of its personality in my mind. If you want a dress watch with a chrono in it, then this is a nice subtle one. I just think it's very much that way around.
