Ball/Garland Chronograph with wild lugs

Curious if anyone here's seen a chronograph with a case like this before. My understanding is that Ball made Garland watches. This one's got (imo) a really fetching 2-tone black dial, it's 38mm case wears excellently, and the Valjoux 22's just been serviced so I don't have to wonder about it mechanically, but the thing that keeps blowing my mind are these lugs! I don't have anywhere near the depth as most here, so I'd love if someone with more experience than I could share if they've seen similar stuff.

Thanks as ever regardless.

Thanks! Yeah, it wasn't one I expected to clean up this nicely.
