Finally came...
Screw-down crown, Seagull St-16 mov't, 200m resistance. The bracelent is not as bad as the price I paid led me to expect, though it still may come off for a horween strap. A little more navy than the initial ad suggested, I was expecting a brighter blue, but I will live with it.
Already ordered my next watch, the next one WILL be a GMT.
