Correct crown for Omega Seamaster 300 ref 14755-61 SC ???

While I like to think I know a few things I always question myself on crowns. Instead of ordering and hoping I was hoping someone can help. I have a 14755-61 SC with an export cal 550 that has a non omega crown and I would like to have the correct one. The replacement non Omega crown on the watch is 5.76 mm.
I saw this on fleabay
https://www.ebay.com/itm/Genuine-Omega-Seamaster-Naiad-Mercedes-Crown-6mm-1mm-thread/303182141600

and was wondering if it might be correct?
Thanks for any help. Or if there is a better source it would be much appreciated.

Original crown for vintage SM 300 is 6,7 mm. X 3,3 mm.
Service crown is 6,7 mm. X 3,1 mm.

The bag you are showing is identifying 165.014 - the second generation case, the 14755 I have is still the straight lug case and a slightly smaller case, are the crowns the same?

165.014 is a straight lug case Seamaster 300 and shares the same case, only the movement holder differs according to the movement.
Moreover the crown is the same with the asymmetric cased 165.024 and 166.024 with Naïad crown.
