I'm no expert but here's my two cents. The Open 'U' logo would suggest a Cal 218, which means that there shouldn't be "MICROTOR" printed on the dial and not to mention that the "R" is wonky. Overall font is off. Lume plots are awfully white. So yup, redial for me.
The seller tells me it's a 204610/2 case reference with 2'053'xxx serial. I've seen earlier 204610 with Cal 215 and so the "Microtor" text could be correct. The "pointy U" can be found on Cal 215 and Cal 218. That said, the text and cross hair printing looks off and the lume looks too fresh. It's more common to see these with chocolate dials, gold coloured text and aged lume. Also look where the cross hair meets the top of the U - it finishes inside the U itself and does not finish cleanly - you will not see that on original dials.
