Hi OF, I want to do a custom engraving on my SMP case back, but do not want to damage my current case back so I hoping perhaps any you have some used case back in your spare parts box? The condition of outer layer is irrelevant, seahorse etc - that all can be damaged, scratched etc, it does not matter as I am going to grind it to a plain surface anyway. The only thing which I care is threads, would be good if new case back would've keept WR100. Thanks
I am fairly sure the 2500/1120 caseback will differ as the watches have different dimensions. You may need to be more specific.
Yes, good point, SMPc caseback is higher than the 1120 caseback, let's specify I am chasing caseback from 2254.50/2531.80 and perhaps 2220.80 can do the job too.
