Puzzle 4:
On first sight it looks like a clock with 12 subdivisions. What does ENE mean? ENE is e.g. a romanian last name or the airport code of an airport in Indonesia. So maybe some letters of numbers nine and six in Romanian or Indonesian? However, apparently, this should be a compass rose (but shouldn't this have 16 subdivisions?) and ENE stands for East-North-East. The arrow to 1 points to West (W) and South (S) or apparently (SSS). Take the first letter of W and the second and third letter of SSS. 18__mv_T
