Rolexman Posted January 13, 2007 Report Share Posted January 13, 2007 (edited) I own a gen Breitling Steelfish and I was wondering what makes this watch waterproof up to 2000m / 6600 ft? There are 3 possible water entry points right (not including the HEV)? - Crystal - Crown/ stem - Case back So why is this watch waterproof up to 2000m and a replica Submariner for example at most 50m? Both have steel case, rubber gaskets, pressed crystal and a specific torque needed to fasten the case back and crown... Any experts on this area?

vmena Posted January 13, 2007 Report Share Posted January 13, 2007 Manufacturing, assembly, post-production quality controls... raw materials, how rep parts match when assembled. A rep is manufactured very fast, and those key parts for waterproofing are not so good quality (in most of them). Example: a crystal not correctly assembled it's a water entry point. Not having inside O ring in case tube facilitate water visiting your mechanism... etc. My MBW 16610 came without tube inner O ring (although it was 50 mtr. resistant). Now it is near 100 mtr. after: inner O ring added, genuine crown and tube, crystal pressed. Maybe this can give you a clue. Quote Link to comment Share on other sites More sharing options...
