Looking for more info... Omega Constellation. Original Dial?

Hi All! I spend quite a bit of time lurking on the forum and appreciate the help I’ve received before. I recently picked up this Omega Constellation and would like some more information if anyone can contribute. I believe the reference # is 2652-17 SC and that it has a 354 movement (pretty sure it’s referred to as a bumper). The serial number is 14763521 which, I believe, puts production in the 50’s. There are a few things that I’m curious about:

1) Most of these that I see have the pie pan dial. This watch has the crosshairs but no pie pan / texture to the dial. Was that common?

2) There’s no SWISS or SWISS MADE on the dial... I realize there isn’t totally consistency in these dials, and there’s a chance I have a redial or something that’s been cleaned, but I’m curious if the absence is indicative of anything in particular?

3) I have to assume the crown has been replaced - is there a way to identify what the replacement part is? And/or is it worth doing?

Thank you for your time, I appreciate any insight you can offer! Chris

Thanks for the quick reply. I definitely had some concern regarding the lack of the Swiss / Swiss Made... I didn’t think the script varied much from other examples but that could easily be that I don’t really know what I’m looking for.

If nothing else, look at the alignment of the minute markers. They are so far off, the script was the last thing I noticed.

Nice one 😉 what’s ref and cal?

Appears there is one for sale 😀
