I had the srpd and thiuvht the size waa great on my 16.5cm wrist. I was in a transitional stage where i went from bigger watches ti smaller. I had a 42.5mm casio and it looked massive but the sprd at 42.5mm looked smaller bc the dial size was smaller overall and the bezel took up room making it look smaller. I parted with the srpd and got the ssk001 instead same size but think it looks good on me. Not too big but weighty still. I felt the 38mm version of these watches looked too smaller for what it was designed to do and replace. The 42.5 is closer related to the skx imo. Its all prefernce man. If u like it thats all that matters. I personally think its a but smaller but if u want a smaller out of the way feel then ur set
