Help with Omega part numbers

Good evening all,

I recently purchased a beautiful silver linen 1967 Seamaster DeVille 165.008 with "automatic" (lowercase) cal. 711 movement.

I am searching for the Omega part number for the sweep center seconds hand and I'm coming up empty. I took a guess and bought one that looked to be a match but had the wrong diameter pinion hole. The one I bought was 250-B 17 1/2 (wrong). The original hand is black, and is very low profile with no nipple on the underside. I'm hoping to find a blued one that fits.....I think that would just make the watch pop!!!

Can anyone refer me to any reference material where I might find this info? Any help is greatly appreciated.

Thanks in advance,
Jay

066TZ1346 is the reference for the grey seconds hand for 165008
