omega speed master broad arroow white dial

Dear members, I have been offered a speedy broad arrow white dial, a watch I really like and that I am trying to find at an affordable price for my pocket.
It seems I found one locally which is the best, I'll see it in person today, but the weird thing is that the date is in black with white numbers instead of the white withblack nmbers, never seen before and the owner do not know why, he got itthis way and demonstratedto me throught the old ad of the previous seller which is still on line.

Do any of you experts know if there'sbeen a run of black date indicators on white dial broad arrow? shall I suspect a repair with missing proper spare that lead to such a modding?

Please try to give me some suggestion thanks

hello and thanks for the reply, I attache a picture and the link to the old sale of it, the seller issued an authenticity certificate for it and made all the testing including the waterproofing, I could see all this today and had the watch on my wrist, amazing .... but your observation is wise, have to think a about it..... https://www.zeitauktion.com/it/omeg...-automatismo-orologio-da-uomo-178-0022-180120

I love the blue accents but, I've never seen one with a black date wheel. The black dial stainless version has a black date wheel (same website too):

after a torough research I could not find another with black date indicator, I think it is not a fake, the site that sold it seems pretty serious and they released many documents (in german!!) following their service , but I would not want to feel that particular out of tune if I should buy it, and moreover I'd not pay the asked price owing to the uncertainty deriving from such a peculiar "modding".... anyway apart from that the watch looks so nice....

Dear Archer, your accurate reply is much appreciated, congrats for your fine knowledge, and many many thanks for the help!

Yep my thoughts were also for a Franken one

I decided to let it go, I'd rather have something that hasn't been modified so I'll wait for another opportunity, thanks for the precious hekp, much appreciated, thanks everybody!
