Advice Needed: Period-Correct Crown for Omega Seamaster 2494-3

Hi! I’m starting the restoration of my Seamaster ref. 2494-3 with cal. 351 and I need advice on sourcing the correct crown. From the service documentation I’ve found, case ref. 2494 should use crown 42025. However, I’ve also seen examples fitted with crown 42023. For a period-correct restoration, should I strictly look for 42025? I’ll attach pictures of the watch without crown, the caseback with reference number, and the relevant extract from the Omega service documentation. Any insight from collectors would be highly appreciated before I commit to buying the crown.
