Hi the Watch Guy.
Do I know you ? Looks like you are from VN? If you like, I can pm you a VNese forum, where you can ask me in the language you prefer.
By looking at the logo with sharp edges, I guess it is a later version of bumper movements, maybe powered by a chronometre 354. The font is faded too much and your picture is not good enough to tell anything. But it looks correct, though.
Ref 2577 18K version ?
Best regards.
Hoi.
Hi Bill.
Yes, it could be a 2520 with a 352 but I still think it's something newer. By looking at the logo with sharp edges, I believe it is powered by something newer than 352's
Here, I have some pics of the round logo of 2520's
Best .
Hoi
