Which chronograph to get?

I'm going to get a mech/auto chronograph for me burfday. Looking at 8R48/NE88 options, Lorier Olympia and Pitzmann 3 are top contenders. Size is a factor as I have spindly wrists, so 38-40mm preferred. The Seikos are a bit large at 42mm but still considering them. Any other good options for a mechanical chrono that isn't enormous?
Thanks!
