Has anyone ever switched hands on a Seagull ST-19 manual wound chronograph movement?

I just bought an Alpha Newman Daytona with a black dial and I'm not crazy about the luminosity of the hands. I would like my watchmaker to swap them out for me for larger, more luminous hour and minute hands.

Does anyone know what size hands will fit this movement? Hands are categorized by the size of the mounting hole right?

Thanks
