You need to get out your jeweler's loupe (best at 5x & 10x)... and look for the threads to "*****" (ski-rue) down your winder-stem (not a lock).
(Features a Ski-rue down crown & back case)
YOU can pretty much be assured that if the "stem" collar is malfunctioning (broken) the "water-proof" element is compromised (that's most likely the least of your troubles).
More importantly... if the STEM does not properly "tighten" it can cause further damage against gears which MUST align with it... further it can come all the way out and be lost... Not an inexpensive part.
Best direction would be to get it serviced by an authorized agent.
