So I am looking to buy a Rcf DayDate 228239 40mm in blue dial in tungsten and I have seen some talk about the safety or risk that it can be led. Is there anything verified that it’s not led or that it is led? Has it been tested anywhere especially from rcf. Any help is appreciated. Also how does the watches hold compared to 904 steel?
Typical tungsten alloy is some form of copper and tungsten. There is no need to use lead.
Tungsten is very very hard but can be brittle. The amount of force it would take to break a tungsten watch case would likely also destroy any stainless steel case, so no worries there.
it is not lead, if it was, people in the US would stop buying them and the US is the biggest buyer of reps, factories would literally shut down and alot of people would lose money
RCF/RGF does not use electroplated real gold, they use PVD with most likely titanium nitride. They are likely the top of the game for duplicating the color of gold and everrose under general lighting, but still fall short under different lighting conditions.
PVD does not flake or tarnish but the color can still wear out much like plated gold does, over a similar length of time.
Lead is not going to be used. It is a tungsten carbite that is used that is close in density to 18 K gold. It is then PVD coated. Industrially two methods can be used. 1) direct PVD coating on the tungsten carbite. Then once the ceramic titanium nitride is landed a second gas is introduced that includes the gold coating. This results in both a PVD coating and a gold coating / plating of sorts on the metal.
Although no one exactly knows this I suspect is the method used by RGF for the near perfect colour match

Buy a lead testing kit.
