A while back before I knew bettter, I bought a sterile watch case on ebay that was advertised to suit eta 2836/2824 and ST2130. As I now understand it ; if a case is built for a 2836 - a 2824 movement we'll not work ( due to stem hole not lining up properly with stem mvt ) and conversely, if the case is made for a 2824, the 2836 obviously won't work due to the fact that it is too thick.
Now, to all those who know more about this, is there a way to tell for which of the two eta mvts the case is made for. Without having to buy both movements and try them out. I emailed the seller whom I have purchased more times to ask if he had more details about what he sold me and honestly said he did no know apart that all he knew was that it was 2836/2824.
I measured the internal with a Vernier caliper where distance from dial seat to stem hole centre was 2.2mm and to the edge of the case from dial seat was 5.5mm. If these figures mean anything??? Thanks in advance!!
