I'm guessing 2877 and 2577, but would appreciate help from the experts. Many thanks in advance.

Need a shot of the back to see the position of the lugs.

330/332 base movements (subseconds are 30.10 mm)

351 SS are 28.10 mm as is 342 subseconds.

471 is 25mm

500 is 28mm

550 is 27.9

A check of crystal OD diameters from the crystal charts can also give an indication what case the dial will fit in. This in turn can often identify the movement.

I usually look for case/dial combinations what fit the movements I have.

My guess is it's a reference that uses caliber 505, but I don't know more than that.

I think you are right with your assumption that it is for 2577

Known dial variant for a 2577, size is also correct. I'd be very surprised if it didnt fit on a cal 351/352/354. Nice find!
