highoeyazmuhudee Posted September 12, 2008 Report Share Posted September 12, 2008 our reps are 316L which is what most stainless jewelery is.... 904L is in house ROLEX only. 316L is surgical grade and used in such settings... 440 i believe doesnt have the same salt water resistance as 316 but is a harder metal... why so curious?

greg_r Posted September 12, 2008 Report Share Posted September 12, 2008 Reps are going to be 220 (for the real cheapies) and 316 for everything else. 904 is found in gen Rolex only, 440 is only gens - there are no reps made of 440l steel.

Tribal Posted September 12, 2008 Report Share Posted September 12, 2008 440 was taken on the older MBW Rolexes. Quote Link to comment Share on other sites More sharing options...
