呢度有 Jörg 講條 gap 嘅用處
https://forums.watchuseek.com/f36/crack-case-my-new-stowa-flieger-993000.html
Please note, that the "gap" at the 6 o´clock position in the case is on each and every case of our watches. (besides the Marine Original) This "gap" has the following technical background:
Its function is to open the case (for cleaning the movement or for repair) easily for the watchmaker without making scratches to the case surface.
We can guarantee, that this "gap" is only a technical purpose and not a production error or a defect.
