I am not seeing 2577-12 in the chart of the first page.
Got this project out of the drawer since I am working on bumper movements
I have a concern that the lugs are too thin when compared to my 2576 cases. Looks like they may be a bit over polished.
The profile view looks alright to my untrained eye.
Sometimes it feels like the back does not really fit the midcase.
I did get a new case tube and clover crown for this. But these concens caused me to put it aside for a bit.
Over the years I have collected more bumper movements. I have plates with as many as 7 or 8 serial numbers. Four including this one probably fit 351/354. So I was looking at the chart to see which SN might fit best (and not confuse people when I am done with it.)
Have two really similar almost identical dials. One is marked Seamaster, but does not have swiss at the bottom. The other dial has the swiss but no Seamaster. Tasteful repaints do not bother me (since I studied how to do it.) The dials do not show signs of overpainting or furniture removal. The 'plain' dial does suffer from a fingerprint stain at the 3 which shows more in photographs. (this is shown in the bench thread relating to these parts.)
Which dial would be best in the 2577 case? I now have both a 351 and a 354 movement so same question.
I did get the 2635 case which also could take either movement.
the 2577-12 (not shown) back does have a really faint Seamaster engraving (along with the initials of a prior owner/caretaker.)
