Not so long ago, I became the owner of this watch.
I'm ask for help in determining their authenticity. Is the dial original? I haven't seen such an inscription on the 503 caliber rotor. I would be grateful for any information!!
Are the marks on 12, 6 and 9 original? In those photos of 2992-1 that I find they are different. Or were there different options? And yet, I do not find completed sales of 2992-1 in the ebay archive. How much can they cost?
Thank you in advance!
