Vintage Omega 30T2 SC Ref 2242/3 - Sector Dial / Originality

Hello everyone,


I recently acquired this vintage Omega and would love to hear your expert opinion on the dial:


Ref: 2242/3 (Steel case)


Cal: 30T2 SC (Serial number: 10,506,172, ~1945)


Dial: Two-tone sector dial with radium dots and printed numerals 12, 2, 4, 6, 8, 10.


My questions:


1. Is this sector dial 100% factory original, or do you see any signs of a refinish/redial?


2. Are the hands and crown correct for this reference?


Thanks in advance for your help!
